TPR-6

Advantages at a glance

Monitoring 6 to 14 RTD / Thermistor temperature inputs.The TPR-6 accurately creates "Thermal Levels" of theheat increase to protect the motor from abnormal heat in the windings and or bearings. Self test procedure protects against disconnected sensors and operator faults. (see below)

*Advanced microprocessor based circuitry
*Display of RTD's or Thermistor's Operating Data, Fault and Statistics
*Programmable inputs and outputs
*RS 485 communication, MODBUS protocol, for remote setting and supervision
*Easy installation & friendly operation
*Two protection levels for Alarm and Trip
*Selection between Trip and Trip fail-safe
*Analogue Output related to any input or inputs combination
*RTD / Thermistor selection via Dip Switches
*Disconnected sensor protection
