TR600 RS485 thermal relay

The Pt 100 thermostat TR600 is a temperature controller and monitors up to six Pt 100 sensors at the same time. Six switching points and six relays permit almost any combination of switching action. It also can select the highest temperature of a group of three or six sensors. Programming is very variable and simple.

Due to the fact that 6 type Pt 100 sensors can be connected, the unit is especially suitable for temperature monitoring wherever up to 6 different measuring points must be monitored simultaneously:

• motors and generators with simultaneous monitoring of bearings and coolant.
• transformers with additional monitoring of the core temperature also.
• power machines and plants

Approval
