What is the Wago 857-500?
Short description:
WAGO's frequency signal conditioner collects 0.1 … 120 kHz signals from NAMUR, NPN or PNP sensors and converts them into a standard analog signal.
Features:
PC configuration interface
Signal acquisition from NAMUR, NPN or PNP sensors
Calibrated measurement range switching
3-way electrical isolation with 2.5 kV test voltage
