Single Function Relays

TCR9C

Temperature Controller

Description

The solid-state TCR9C series relays are designed for dedicated temperature control of resistive loads. These relays

feature a single setpoint controller with high-current, solid-state output. The TCR9C relay is a low-cost, modular approach

to accurate temperature control and supports loads up to 20 A. The efficient mounting surface allows for utilization

of equipment as the heat sink.

Operation

Setpoint Control: TCR9C is a single setpoint temperature controller. When the thermistor resistance is high (above the

setpoint), the solid-state output is ON. When the thermistor resistance decreases (temperature increases) to the setpoint

or below, the output turns OFF. It should be noted that temperature differential (under and overshoot) is largely due to

the system as a whole. The mass of the system, size of the heaters, and sensor all play an important part. Single setpoint

control is best when there is little or no lag time between the heater and sensor, and when the heater is not oversized.
