WAGO 857-531 — Signal Conditioners

Short description: This threshold value switch for analog signals monitors standard analog signals and reports signals exceeding a preset threshold. Configurable digital switching output: GND switching: The digital output (DO) is switched to “GND” for all input values that are smaller than the lower switching threshold or greater than the upper switching threshold. U s switching: For all input values that are smaller than the lower switching threshold or greater than the upper switching threshold, the digital output (DO) adopts the value of the supply voltage. The preset switching thresholds are 0 % and 100 % (±0.25 V / ±0.5 mA) of the input measurement range. The switching thresholds can be adjusted via the interface configuration software. Features: PC configuration interface Changeover relay output Calibrated measurement range switching Threshold value configuration via DIP switch and teach-in function via push/slide switch 3-way electrical isolation with 3 kV test voltage
