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. *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
