Three-Wire RTD Inputs
Note:
Three-wire inputs such as thermistors and RTDs can be handled by
switching the two common wires and connecting the third wire of each
sensor to the TP terminal and to the temperature meter.
• Connect like color leads to terminals 1A & 1B, 2A & 2B, 3A & 3B, etc.
• Connect odd color leads to terminal TP.
• Connect outputs A, B and TP to the temperature meter.
Thermocouple Inputs
