1 Functional description
The TRM500 is a versatile temperature controller with switching current up to 30 A. The device has a
universal input for a wide range of resistance thermometers and thermocouples as well as a digital
input. It is provided with a relay output, an alarm output, a DC logic output. The outputs can be
configured for different tasks (see Appendix A). The controller can be quickly configured by using three
keys.
Functions:
– On-Off or PID control (see Fig. 1)
– Manual control
– 20 mm, 4 digit display, 2nd display optional
– Digital input filter with an adjustable time constant
– Custom 2-point linearization
– Digital input (remote start/stop or setpoint change) (see Appendix D)
– Temperature range alarm
– Auxiliary alarm output
– Additional logic output (SSR)
– Configurable outputs (see Appendix A)
– Autotuning function (see Appendix C)
– Cold junction compensation
– Input calibration (see Appendix E)
– 9 status LEDs

2 Safety precautions
Make sure that the device is fully disconnected from auxiliary power before
starting any commissioning or repair work.
CAUTION Connect the power supply only after the wiring has been completed.
DANGER Do not use the device where it is subjected to flammable or explosive gas.
