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.
