Pt 100-Temperature Relays Type TR
Pt100-Temperature-Relay Type TR600
Digital, 6 Sensors, 6 Limits
TR600 Temperature Relay for 6 Sen- outputs i.e. for remote displays or further evaluation.
sors Pt100 Programming is very variable and simple.
The Pt100-temperature relay
TR600 monitors up to six sensors Due to the fact that 6 type Pt100 sensors can be con- 1
Pt100 (RTD) at the same time. Six nected, the unit is especially suitable for temperature
switching points and six relays monitoring wherever up to 6 different measuring points
permit almost any combination must be monitored simultaneausly:
