Description

Short description:

WAGO’s RTD TC temperature signal conditioner for RTD sensors, potentiometers, resistors and thermocouples monitors and reports signals of up to two switching thresholds. The sensor and status information that is collected is also converted to a standard analog signal.

Features:

  • A relay with changeover contact reacts to configured measurement range limits (on/off switching delay and threshold value switch function can be configured with up to two threshold values)
  • Configurable Pt factor
  • Adjustable software filter
  • Simulation of input/output response via interface configuration display
  • Input of customer-specific sensors via interface configuration software
  • Safe 3-way isolation with 3 kV test voltage per EN 61010-1
  • Analog unipolar/bipolar signals (current/voltage) at output
  • Additional digital signal output for configured measurement range limits
  • Adjustable transfer characteristic
