2857-535/000-001 - Temperature signal conditioner; Configuration via software; Supply voltage: 24 VDC
- Brand: Wago
- Product Code: 2857-535/000-001
Description: Short description: WAGOs RTD TC temperature signal conditioner for RTD sensors, potentiometers, resistors and thermocouples monitors and reports signals for up to two switching thresholds. The sensor and status information that is collected is also made available to a higher-order device (e.g., a PLC) via a bus connection. 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 the interface configuration software Safe 3-way isolation with 3 kV test voltage per EN 61010-1 Output-end RS-485 interface with Modbus protocol Terminating resistor can be adjusted at the output Adjustable transfer characteristic
