Current Output
Field Transmitters Note 1. All 2100-A16 analogue inputs are
differential. Exceeding 18V peak between
any 2 inputs, or any single input will cause
errors on ALL channels.
In example 2, the peak voltage is
calculated by multiplying the max mA out
of any transmitter, by the sum of the
resistances in the transmitter loop, then
adding any common peak voltages.
eg:(refer to Connection Example 2)
If the transmitter has a 35mA max, the
2100-A16 has 25input resistance; and if
achart recorder has250inputresistance:
There is a 2V peak common voltage.
=>35mAx(25+ 250) +2V = 11.63V peak.
This is fine, as it is less than 18V.
Note 2. For mAinputs a jumper must be installed.
Failure to install a jumper will cause errors
onALL channels. J1 for channel 1, J2 for
channel 2, etc. The jumpers are located
directly behind the 3 terminals for each
respective channel. They can be installed
without removing the cover.
Note 3. Inputs can be used as digital inputs for
sensing a clean, voltage free, field contact.
Note 4. All cables must be screened, and the
screens earthed at one end only.
Note 5. Voltage freecontactvaluesmustbebrought
in through ‘tags’in the Scada Software.

Note 1. AllT/C inputs are differential.Exceeding18V peak between
any 2 inputs, or any single input will cause errors onALL channels.
Note 2. It is recommended that theT/C’sbeisolatedfromeachother
and earth. Isolated junction, mineral insulated T/C’s are recommended.
Note 3. For accurate T/C measurement, especially low temp: *The
cover must be fitted. *Avoid drafts and temperature differences across
terminals. *Once installation is complete, close the cabinet door and allow
the cabinet to reach equilibrium. This may take several hours. *Place all
theT/Cprobesintoacalibrated thermal bath attemperatureofinterest.
Any errors can be zeroed out in software.
Note 4. All T/C’s are referenced to the on board cold junction
compensation(CJC)temperaturesensor. PriortoRev 1.3theCJC sensor
islocatedbehindterminal24.FromRev1.3onwardstheCJCtemperature
sensor is locatedbehind terminal1. Alternativelyone of inputs 1 to 8 can
be selected in the Scada software as an RTD CJC for inputs 1 to 8,
and one of inputs 9 to 16 can be selected in the Scada software as an
RTDCJC for inputs9 to16.Themounting orientationof the 2100-A16,
(eg vertical or horizontal) affects the CJC accuracy of different inputs.
The affects are more noticeable on small temperature ranges. For
examplemountingthe2100-A16horizontalwill cause the all the upper
terminals to be warmer compared to all the the lower terminals. Any
errors can be zeroed out in software.
Note 5. Cables must be screened & screens earthed at one end only.
Note 1. All RTD inputs are single ended. ie all the
2nd ‘B’ terminals are internally connected.
Note 2. It is recommended that theRTDsbe isolated
from each other and earth.
Note 3. Inputs can be used as digital inputs for
sensing a clean, voltage free, field contact.
Note 4. All RTD cables must be screened, and the
screensearthed at oneendonly.All thethree
wires must be the same resistance. (ie. the
same type and size.) Refer to ‘Wiring and
Installation’for recommended types.
Note 5. To minimise lead resistance errors, 3 wire
RTDs should be used. If 2 wire RTDs are
usedsmall offseterrorscan be compensated
for in software.
Note 6. For voltage free contactsuse RTD60 to 850

1/ Power must be off before installing the 10 way ribbon cable and 2100-ARI board
supplied with the 2100-R2.
2/ Remove the cover off the 2100-A16.
3/ An exchange cover, with a precut slot for the ribbon cable, is available free of
charge from your supplier. P/N: 2100-A16-COVERSLOT.
Alternatively you may wish to modify the existing cover:
Cut a 1mm slot, 20mm deep, just below terminal numbers 1, 2 & 3.
Carefully smooth the edges of the cut so the ribbon cable does not get damaged.
4/ The 2100-ARI is supplied with the ribbon cable attached. Use antistatic precautions
when installing. Carefully orientate the 2100-ARI board as shown above. Locate the
two plastic standoffs over the corresponding holes in the 2100-A16, and the 10 pin
connector. Once all three are aligned, push the 2100-ARI firmly into the 2100-A16.
5/ Connect the other end of the cable to the 2100-R2. Ensure both ends of the cable are firmly connected.
6/ Slide the cable into the slot, and replace the cover on the 2100-A16.

2100-A16 Rev1.3 Relay Output Expansion - Using 2100-R2 Relay Expansion.
Output relay expansion is available using the 2100-R2, 16 relay output expansion module. This allows the 2100-A16 to
stand alone as a 16 channel controller / alarm unit. The 2100-R2 relay outputs can be used for any combination of
control and alarm functions. The control parameters for each of the 16 controllers is downloaded from user friendly
Microscan Software, and stored in permanent memory on the 2100-A16. These parameters include Setpoint (SV),
Output Switching Differential,Auto / Manual, Manual Output Setting, DualAction Control, SingleAction Control, Heat /
Cool, Heat Only, Cool Only. The 16 controller / alarms will operate unaffected by computer power downs, reboots, etc.
The relay outputs can also be accessed directly from the Scada.

2100-A16 Analogue Signal Converted to Frequency for a PLC, using a TWI-FO.
Description.
The TWI-FO converts 4~20mA from a 2100-AO to a frequency output. (Typically 10~1010Hz, but this is rangeable.)
A PLC with two digital outputs and one digital input can receive sixteen multiplexed analogue inputs.

‘Read Only From 2100-A16’ and ‘Read and Write to 2100-A16’Protocols are both available from Intech Instruments in
‘WORD’ format, free of charge.
Read Message is PLC compatible read DM area. 2100-A16 protocol is the protocol used by Microscan to access data
in stations. Both protocols useASCII, except 2100-A16 uses IEEE754 to represent floating point numbers.
2100-A16 ‘Modbus RTU/TCP’ Communication Protocol.
Note 1: This section only applies to an 2100-A16 with Modbus RTU Protocol.
Note 2: Can be used on Modbus TCP with a Modbus TCP to RTU Bridge. ie Schneider Electric ‘174 CEV 300 20’.
Note 3: 2100-ME Memory Board cannot be used when Modbus RTU protocol is used.
Modbus RTU Comms Specifications:

2100-A16 Rev. 1 PLC RTX Fail Safe System
The PLC uses one channel of the 2100-A16 to verify that theA16 is reading the channel correctly,AO1 is working and
the clock and reset/BCD channel select is working.
Test Channel = spare channel on 2100-A16, set to RTD 0-850C.This has a PLC relay connected which is used to short
out A-B, under the PLCs command. Do not use channel 1 as the test channel.
Sequence of operation.
1. The PLC reads the required channels as normal.
2. The PLC then advances to the test channel (the next free channel or channel 16)
3. The test channel is read.
4. The relay changes state to alter the reading of the test channel.
5. 1. to 4. are repeated. If the reading on the test channel does not alternate between 4 mA and 10 mA as the relay
changes state, within the specified tolerances as listed below then there is a fault in the system. The PLC software
should be setup to detect these values as the relay changes state.
