Pt 100-Temperature Relay Model TR400, 4 Sensors, 4 Limits, digital, 2 analogue outputs (Ordering Code T224380)

Site for Programming TR400

The Pt 100 thermostat TR400 is a temperature controller and monitors up to 4 Pt 100 sensors at the same time. 4 switching points and 4 relays permit almost any combination of switching action. It also can select the highest temperature of a group of 3 or 4 sensors. The temperatures of two sensors or groups of sensors can be issued to 2 analogue outputs i.e. for remote displays or further evaluation. Programming is very variable and simple.  Due to the fact that 4 type Pt 100 sensors can be connected, the unit is especially suitable for temperature monitoring wherever up to 4 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
