What is the Wago 857-401?

Short description:

This configurable signal conditioner converts, amplifies, filters and electrically isolates standard analog signals.

Digital switching output (DO):

The digital switching output (DO) allows signaling of a message. Two switching behaviors can be selected for the edge:

GND switching: For all values below the lower threshold or above the upper threshold, the digital output switches to “GND.”

U s switching: For all values below the lower threshold or above the upper threshold, the digital output (DO) matches the supply voltage level.

The preset switching thresholds are 0% and 100% of the input measurement range. These thresholds can be adjusted via the PC configuration interface. The switching threshold hysteresis is 5 mV/5 µA.

Features:

PC configuration interface

Calibrated measurement range switching

Analog unipolar and bipolar standard signals at the input

Clipping capability

for analog signal limitation to output end values

3-way electrical isolation with 2.5 kV test voltage

Notes

Safety InformationInput and output must be safely isolated from any hazardous live parts!
NoteAdditional setting options via the WAGO Interface Configuration Software, Terminals 4 (GND 3) and 8 (GND 3) are internally bridged. Current carrying capacity between terminals 4 and 8: max: 1 A
