- Brand: Wago
- Product Code: 2857-533/000-001
Description: Short description: WAGOs RTD threshold value switch for RTD sensors, potentiometers and resistors monitors and reports signals for up to two switching thresholds. Features: Both digital signal output and relay with make contact react to configured measurement range limits (on/off switching delay and threshold value switch function can be configured with up to two threshold values). Configurable RTD factor Adjustable software filter Input/output response simulation via configuration display Safe three-way isolation with 4 kV test voltage per EN 61010-1 For railway applications
