Laird`s TC-XX-SR-54 Temperature Controller

TC-XX-SR-54
Temperature Controller
The TC-XX-SR-54 temperature controller is a microcontroller based device that can be incorporated
into a thermoelectric assembly (TEA) to add integrated temperature control. The TC-XX-SR-54 is a
bi-polar temperature controller for cooling/heating of thermoelectric assemblies requiring precise
temperature control accuracy. The TC-XX-SR-54 has 3 programmable fan outputs, alarm output relay,
alarm condition LEDs. The parameters will be programmed at the factory according to the customer
requirements. Custom configurations are available, however MOQ applies.
FEATURES
• Operation in cooling and heating modes
• Regulation mode is ON/OFF, PID, Power
• Input power range can accommodate
16 to 60 VDC, nominally 16 to 48 VDC
• Preprogrammed set points
• Contacts are available for fans,
thermoelectric modules, NTC thermistor
sensor, overheating thermostat switch,
alarms; some features sold on custom
configurations only
• USB communication interface
MARKETS
• Battery Backup Cabinets
• Medical diagnostics
• Analytical instrumentation
• Chillers (liquid cooling)
PERFORMANCE
BENEFITS
• Standalone operation
• Control temperature, from -20°C to +100°C
(-4°F to +212°F) with the standard NTC sensor
• Temperature resolution of max 0.13°C (-10°C to
+50°C)
• Use with NTC sensors only
• Pulse width modulation of output: (Base
frequency of 8 kHz)
• Control stability of ±0.13°C (-10° to +50°C)
• Three alarm temperature sensor inputs with
adjustable alarm set points
• Alarm relay output, normally closed (will open
on alarm): 1A at 125VAC/110VDC
• Adjustable fan speed
• Tachometer sensor inputs provided to measure
the speed of one external and two internal fans
• Overheating thermostat switch input available
to sense an over temperature condition that will
turn off power to TEA/fans and microcontroller;
a thermostat is required for operation
• Alarm LED outputs available indicate type of failure

SPECIFICATIONS
Alarms
Low Voltage
Alarms if the input voltage is lower than the programmed minimum level
High Voltage
Alarms if the input voltage is above the programmed maximum level
Battery Delimiter
Turns on the modules and fans only if battery voltage is above DELIM_H
value and turns off everything if battery voltage drops below DELIM_L
Tachometer Int Fan 1 & 2,
Ext Fan
If the RPM signal is lower/higher than the programmed minimum/
maximum level, error is indicated and outputs can be turned off
Fan Failure/Missing
If fan rotor fails, fault is indicated
Fan Overcurrent
If fan draws over current, fault is indicated
Temperature Sensors 1,2/3
short/open/out of range
If the temperature sensors are short/open or out of range,
fault is detected and outputs can be turned off
TEM Over Current/Missing
Fault is indicated and fans outputs can be turned off
Note: All programming of parameters are conducted by Laird. For any or all of the above fault condition/s, controller can be
programmed to trigger the alarm relay and TEM/ Fan outputs can be programmed to be turned off
Temperature Regulation
ON/OFF mode (dual set
point)
Controller switches the TEM output between full power and zero
power at the programmed set point and hysteresis
PID mode ( single set point)
Controller can be selected to switch between P, PI, PD or PID modes
PID mode ( Dual set point)
Controller can be selected to switch between P, PI, PD or PID modes
Power mode
Depending on the value of external potentiometer the output
can be controlled
Programmable Control
Set Point/s
Can be programmed at any value between -40°C to +100°C
