DESCRIPTION
The Model C48 Timer is available in Single or Dual Preset models. The
C48T features a 7 segment, 2 line by 6 digit reflective or backlit LCD display.
For the backlit versions, the main display line is red and shows the timer value.
The smaller secondary display line is green, and can be used to view the preset
values or output time values.
The C48 timer can be configured for a variety of different operating modes
to meet most timing application requirements. Twelve timing ranges are
available from thousandths of a second to hours and minutes. Decimal Points
are used to separate the time units (hours, minutes, seconds). Timing can be
cumulative or can reset and start upon each power cycle. “On Delay” or “Off
Delay”, “Single Shot”, “Repetitive auto cycling” modes are all supported.
The Timer can also be configured to Continue or Stop timing upon reaching
Preset. The display can be programmed to stop at the preset value (Reset to Zero
mode) or zero (Reset to Preset mode), or automatically reset to zero or preset
and hold. Once stopped, the timer can be restarted by manually resetting it, or
it can be programmed to restart when power is reapplied.
The C48 Timer has a Run/Stop Input, 3 programmable User Inputs, and a
programmable front panel function key. The Run/Stop and User Inputs can be
configured as sinking (active low) or sourcing (active high) inputs via a single
plug jumper. The user inputs and the front panel function key can be configured
to provide a variety of functions.
Four front panel push-buttons are used for programming the operating modes
and data values, changing the viewed display, and performing user
programmable functions, e.g. reset, etc. The C48T can be configured for one of
two numeric data entry methods, digit entry or automatic scrolling. The digit
entry method allows for the selection and incrementing of digits individually.
The automatic scrolling method allows for the progressive change of one
through all digit positions by pressing and holding the “up” or “down” button.
The Dual Preset models are available with solid-state or Relay outputs. The
Single Preset model has a solid-state and relay output in parallel. All solid-state
outputs are available in a choice of NPN current sinking or PNP current
sourcing, open-collector transistor outputs. All relay output boards are field
replaceable.
The optional RS-485 serial communication interface provides two-way
communication between a C48 and other compatible equipment such as a
printer, PLC, HMI, or a host computer. In multipoint applications (up to thirty-
two), the address number of each C48 on the line can be programmed from 0 to
99. Data from the C48 can be interrogated or changed, and alarm output(s) may
be reset by sending the proper command code via serial communications. PC
software, SFC48, allows for easy configuration of controller parameters. These
settings can be saved to disk for later use or used for multi-controller down
loading. On-line help is provided within the software.
The unit is constructed of a lightweight, high impact plastic case with a
textured front panel and a clear display window. The front panel meets NEMA
4X/IP65 specifications when properly installed. Multiple units can be stacked
horizontally or vertically. Modern surface-mount technology, extensive testing,
plus high immunity to noise interference makes the C48 Timers extremely
reliable in industrial environments.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons
or equipment in the event of a fault to the unit.

2. POWER REQUIREMENTS:
AC Versions (C48CXXX0X):
AC Power: 85 to 250 VAC, 50/60 Hz, 9 VA max.
DC Power: 11 to 14 VDC @ 150 mA max. (Non PNP output models)
Note: Models with PNP current sourcing outputs must be powered from AC.
DC Versions (C48CXXX1X):
CONTINUOUS:
DC Power: 18 to 36 VDC; 5.5 W max.
AC Power: 24 VAC ±10%; 50/60 Hz; 7 VA max.
Note: The +10% tolerance range on AC input voltage must be strictly
adhered to. DO NOT EXCEED 26.4 VAC.
PEAK (START-UP CURRENT):
AC or DC Power: 500 mA peak start-up current for 10 msec max.
DC OUT (VSRC IN) - Terminal 10
For units which do not have PNP current sourcing outputs, this terminal
provides a DC output for sensor power (+12 VDC ±15%). The
maximum sensor current is 100 mA.
For units with PNP current sourcing outputs, this terminal serves a dual
purpose depending on the application’s PNP output voltage level and
current requirements.
1. The terminal may be used as a +12 VDC output for sensor power.
In this case, the PNP output voltage level will be +12 VDC
(±15%). A maximum of 100 mA is available for the combination
of sensor current and PNP output sourcing current.
2. If a higher PNP output voltage level or additional output sourcing
current is desired, an external DC supply may be connected
between the “DC OUT (VSRC IN)” and “COMM.” terminals. This
supply will determine the PNP output voltage level, and must be
in the range of +13 to +30 VDC.
An external DC supply can also provide the additional output
sourcing current required in applications where two or more PNP
outputs are “ON” simultaneously. However, the maximum current
rating of 100 mA per individual output must not be exceeded,
regardless of external supply capacity.
3. MEMORY: Nonvolatile E2PROM retains all programmable parameters and
timer values.
4. SENSOR POWER: +12 VDC (±15%) @ 100 mA max.
5. INPUTS: Run/Stop, Usr. In1, Usr In2, and Usr. In3.
Configurable as current sinking (active low) or current sourcing (active high)
inputs via a single plug jumper.
Current Sinking (active low): VIL = 1.5 VDC max, 22 KWpull-up to 5
VDC.
Current Sourcing (active high): VIH = 3.5 VDC min., VIN max = 30 VDC;
22 KWpull-down.
Run/Stop Response Time: 250 msec max.
User Input Response Time: 5 msec max.
6. TIME ACCURACY: ±0.01%
7. OUTPUTS: (Output type and quantity are model dependent)
Solid-State:
NPN Open Collector: ISNK = 100 mA max. @ VOL = 1.1 VDC max; VOH
= 30 VDC max.
PNP Open Collector: ISRC = 100 mA max.(See note); VOH = 12 VDC
±15% (using internal supply); VOH = 13 to 30 VDC (using external
supply).
Note: The internal supply of the C48T can provide a total of 100 mA for
the combination of sensor current and PNP output sourcing current.
The supply voltage is +12 VDC (±15%), which will be the PNP output
voltage level when using only the internal supply.
If additional PNP output sourcing current or a higher output voltage
level is desired, an external DC supply may be connected between the
“DC Out/In” and “Comm.” terminals. This supply will determine the
PNP output voltage level, and must be in the range of +13 to +30 VDC.
An external supply can provide the additional output sourcing current
required in applications where two or more outputs are “ON”
simultaneously. However, the maximum rating of 100 mA per individual
output must not be exceeded, regardless of external supply capacity.
Relay: Form A contact, Rating = 5 A @ 250 VAC, 30 VDC (resistive load),

MULTIPLE UNIT STACKING
The C48T is designed for close spacing of multiple units. Units can be
stacked either horizontally or vertically. For vertical stacking, install the panel
latch with the screws to the sides of the unit. For horizontal stacking, the panel
latch screws should be at the top and bottom of the unit. The minimum spacing
from center line to center line of the units is 1.96” (49.8 mm). This spacing is
the same for vertical or horizontal stacking.
Note: When stacking units, provide adequate panel ventilation to ensure that the
maximum operating temperature range is not exceeded.

RELAY OUTPUT BOARDS
ONE SHOT TIMING CYCLE
Proper wash down mixture for a food processing plant is an important
factor in maintaining the clean environment required. A disinfectant solution
is added to the mixing/holding tank used for the wash down cycle. When the
holding tank is near empty, a level transducer activates the filler pump. A
C48TS is used to turn on the disinfectant solution pump for a preprogrammed
amount of time during the filling process of the holding tank.
When the filler pump starts, a momentary contact closure activates User
Input 1, resetting the C48 Timer. The timer begins the timing cycle since the
run terminal is connected to common. The normally open relay contacts close
at the timer reset signal activating the disinfectant solution pump. When the
programmed preset is reached, timing stops and the relay deactivates, turning
off the pump controlling the disinfectant solution. The C48 Timer’s preset
cycle time may be changed according to the manufacturer’s concentration
level of the disinfectant.
