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.

Safety precautions

Make sure that the device is fully disconnected from auxiliary power before

WARNING

starting any commissioning or repair work.

Connect the power supply only after the wiring has been completed.

CAUTION

DANGER

Do not use the device where it is subjected to flammable or explosive gas.
