1. Introduction
Figure 1-1. SDM-CD16ACA face panel
The SDM-CD16ACA has 16 AC/DC relay control ports (see Figure 1-1 [p. 1]). Each relay port can be
controlled by a data logger or controlled manually with a manual override toggle switch.
The toggle switch has three positions: ON and OFF for manual override, and AUTO for data
logger control. In the ON position, the common (COM) and normally open (NO) contacts are
closed (see Figure 4-1 [p. 6]). In the AUTO position, the state of the relays are controlled by the
data logger control ports.
The SDM-CD16ACA is a synchronously addressed data logger peripheral. Three ports on the data
logger are used to address the SDM-CD16ACA, then clock out the desired state of each of the 16
control ports. Up to 15 SDM-CD16ACAs may be addressed, making it possible to control a
maximum of 240 ports from the three data logger ports.
Compatible Campbell Scientific data loggers use the CRBasic instruction SDMCD16AC() to
control the SDM-CD16ACA.
NOTE:
The SDM-CD16ACA is an improved version of the SDM-CD16AC with better individual
contact ratings. Both the SDM-CD16ACA and the SDM-CD16AC are controlled with the same
CRBasic instruction, SDMCD16AC().

SDM-CD16ACA 16 Channel AC/DC Controller 2

3. Power considerations
The SDM-CD16ACA power requirements are large compared to most Campbell Scientific
products. For most applications, an external power supply (see Figure 3-1 [p. 3]) is recommended
to power the SDM-CD16ACA.
For some applications, it may be convenient to use the data logger supply to power the
SDM-CD16ACA (see Figure 3-1 [p. 3]). For long-term applications, the lead acid power supply
available with Campbell Scientific data loggers should be used, allowing the batteries to be float
charged. It is not recommended that the data logger alkaline supply be used to power the
SDM-CD16ACA for long-term applications due to its large power requirements.
Figure 3-1. Connection block diagrams
SDM-CD16ACA 16 Channel AC/DC Controller 3

4. Installation
lThe SDM-CD16ACA must be installed in an enclosure that provides a pollution degree 2
environment (normally, only nonconductive pollution; however, a temporary conductivity
caused by condensation may be expected). All Campbell Scientific enclosures meet this
requirement.
lUse copper conductors only.
lWire Range: 30 to 14 AWG
lTightening Torque: 5 to 7 in/lb
lUse minimum 60/75 °C wire.
lInput power must be connected to a class 2 supply only. All Campbell Scientific power
supplies meet the class 2 supply requirements.
CAUTION:
Cables connecting the data logger and SDM device should be kept as short as possible to
minimize the risk of corruption of the signals and damage from induced surges. Where long
cable runs (>3m) are unavoidable and the cables run outside, some extra protection may be
required for the SDM control ports. Please contact Campbell Scientific for further advice.
When connecting wires to the SDM signal ports, please ensure they are at ground potential
before making the connection by touching them to the earth terminal.
For data logger connections, see Table 4-1 (p. 5).
Multiple SDM-CD16ACAs may be wired in parallel by connecting the data logger side of one
SDM-CD16ACA to the next. The CABLE5CBL-L or an equivalent cable is used to connect the
module to the data logger. A 0.3m (1ft) cable length should be sufficient when both data logger
and SDM-CD16ACA are housed within an ENC12/14; a 0.6m (2ft) length may be required if the
data logger and SDM-CD16ACA are housed at opposite ends of an ENC16/18 enclosure.
CRBasic data loggers should use the SDMSpeed()instruction if the cable length is longer than
6m (20ft).
NOTE:
SDM cables in noisy environments need to be suitably shielded.

NOTE:
The CR6 allows SDM operation through terminals C1,C2, and C3 as shown in Table 4-1 (p. 5).
In addition, the Uterminals on the CR6 may be used in the same manner. U1–U3,U5–U8, and
U9–U11 are usable in the same Data,Clock,Enable order as the Cterminals.

Figure 4-1. Switch operation
In most applications, the SDM-CD16ACA acts as a switch (controllable break) in one wire of the
circuit powering the controlled device. One side of this break may have power (hot). Figure 4-2
(p. 6) shows an example.
Figure 4-2. Typical wiring application
4.1.3 Motor control
The SDM-CD16ACA is a UL approved Start/Stop motor controller. In Figure 4-3 (p. 7), a typical
5Amp 115VAC relay contact circuit shows how to control a three phase motor starter in a Motor
Control Centre (MCC). Typically, the data logger will automatically command the appropriate
relay to energize the motor starter. The relay in the SDM-CD16ACA will remain latched until the
data logger program commands that the motor be turned off, at which time the relay will open
the circuit to the motor starter and the motor will stop.
SDM-CD16ACA 16 Channel AC/DC Controller 6

The SDM-CD16ACA can be used to control three phase pump motors, air blowers, and large
control valves in the same fashion.

5. Address selection switches
Each SDM-CD16ACA can have 1 of 15 addresses (0 to 14). Address 15 is reserved for the
SDMTrigger() instruction. Shipped from the factory, the address is set at 00. The following
table shows switch position and the corresponding address (see Figure 5-1 [p. 8]).

6. Data logger programming
In CRBasic, the SDMCD16AC() instruction is used to control the SDM-CD16ACA. Data loggers
that are programmed with CRBasic include the CR6, CR3000, CR1000X, CR800, CR850, and
CR1000. The SDMSpeed() instruction should also be used if the cable length is longer than 20ft.
SDM-CD16ACA 16 Channel AC/DC Controller 8

6.1 CRBasic programming
6.1.1 SDMCD16AC() instruction
Syntax
SDMCD16AC(Source, Reps, SDMAddress)
Remarks
A port on an SDM-CD16ACA is enabled/disabled (turned on or off) by sending a value to it using
the SDMCD16AC() instruction. A non-zero value will enable the port; a zero value disables it. The
values to be sent to the CD16AC are held in the Source array.
The SDMCD16AC() instruction has the following parameters:
Source: The Source parameter is an array which holds the values that will be sent to the
SDM-CD16ACA to enable/disable its ports. An SDM-CD16ACA has 16 ports; therefore, the source
array must be dimensioned to 16 times the number of repetitions (the number of SDM-CD16ACA
devices to be controlled). As an example, with the array CDCtrl(32), the value held in CDCtrl(1) will
be sent to port 1, the value held in CDCtrl(2) will be sent to port 2, etc. The value held in CDCtrl(32)
would be sent to port 16 on the second SDM-CD16ACA.
If the Source parameter is defined as a Long variable, but it is dimensioned less than 16X Reps,
Source will act as a binary control for the instruction whose bits 0…15 will specify control ports
1…16, respectively. In this situation, Source (1) will be used for the first Rep; Source (2) will be used
for the second Rep, and so on.
Reps: The Reps parameter is the number of SDM-CD16ACA devices that will be controlled with
this instruction.
SDMAddress: The SDMAddress parameter is used to define the address of the CD16AC that will
be controlled with this instruction. Valid SDM addresses are 0 through 14. Address 15 is reserved
for the SDMTrigger() instruction. If the Reps parameter is greater than 1, the data logger will
increment the SDM address for each subsequent device that it communicates with.
6.1.2 SDMSpeed() instruction
The SDMSpeed() instruction is used to change the speed at which data is clocked to and from
attached SDM devices. Slowing down the clock rate may be necessary when many SDM devices
are connected to the data logger, or even when a single SDM device is connected over a long
cable.
SDM-CD16ACA 16 Channel AC/DC Controller 9

lMany applications do not require the use of SDMSpeed().
lIf intermittent communications with several devices connected at once is experienced, or
when using long cables, use SDMSpeed() to increase the bit period above the default. Try
doubling the bit period until a stable link is achieved.
lTo maximize communication speeds because of skipped scans, decrease the bit period.
Changing the clock rate is accomplished by changing the bit period of the clock signal. A short
bit period equates to a faster clock rate and faster data transfer. A long bit period equates to a
slower clock rate and a slower data transfer more suitable for long cable lengths or many
connected devices.
The syntax of this instruction is as follows:
SDMSpeed(BitPeriod)
The BitPeriod argument can be a constant or variable integer. If the SDMSpeed() instruction
is not included in the program, the default bit period for the clock line will be used. If the bit
period specified is smaller than the minimum or larger than the maximum, the data logger will
default to the minimum or maximum bit period, respectively. Refer to CRBasic Editor Help for the
default, minimum, and maximum bit period for each data logger.
7. Theory of operation
The SDM-CD16ACA is a synchronously addressed peripheral. C2 and C3, driven high by the data
logger, initiate a cycle. While holding C3 high, the data logger drives C2 as a clock line and C1 as a
serial data line. The data logger shifts out a data bit on C1 (LSB first) on the falling edge of the C2
clock. The SDM-CD16ACA shifts in the C1 data bit on the rising edge of the C2 clock.
The first 8 bits clocked out represent the SDM-CD16ACA address. If the address matches the
SDM-CD16ACA address, the SDM-CD16ACA is enabled. If enabled, the next 16 bits are shifted
into the SDM-CD16ACA, each bit controlling one port, the first of which controls port 1.
When the 16 control bits are clocked in, C2 is held high while C3 is pulsed low then high to latch
the control bits. The data logger then lowers both C3 and C2 to complete the cycle.

8. Program examples
8.1 CRBasic examples
The three program examples discussed in this section are downloadable at
www.campbellsci.eu/downloads/sdm-cd16ac-example-programs. The programs
demonstrate controlling two SDM-CD16ACAs, controlling temperature and fans in greenhouses,
and using an integer instead of an array to set the SDM-CD16ACA control outputs. While the
programs are written for the CR1000X, they will work with other Campbell Scientific data loggers
with little or no modification.
8.1.1 Controlling two SDM-CD16ACAs
The program, SDM-CD16AC-two-sdms.dld, demonstrates using two SDM-CD16ACA modules to
control pumps and heaters based on water level and temperature thresholds.
8.1.2 Control temperature and fans
In program SDM-CD16AC_greenhouse-control.dld, the SDM-CD16ACA is used to control the
temperature between 23 and 28°C in each of five greenhouses. In each greenhouse, the
SDM-CD16ACA controls a heating unit, a refrigerating unit, and an air-mixing fan according to
the following conditions.
Heating unit: Activate when temperature < 23.5 °C. Deactivate when temperature > 25.5 °C
Cooling unit: Activate when temperature > 27.5 °C. Deactivate when temperature < 24.5 °C
Mixing fan: Activate whenever the heating or cooling units are activated. Activate for 5 minutes
out of every 15 minutes.
The program assumes the temperature measurements have been made, and the average
temperature for each greenhouse is computed and residing in the appropriate variable.
Input Location assignments are as follows:
Variable array Description
Temp(5) Avg temp, greenhouse 1..5
Heat(5) Heater control, greenhouse 1..5 SDM-CD16ACA
