What is the Wago 857-809?
Short description:
WAGO's potentiometer signal conditioner records resistance signals (e.g., from potentiometers) and converts them into a standard analog signal. The device is supplied with 24 VDC (nominal voltage). It is set via DIP switch or push/slide switch.
Features:
PC configuration interface
Calibrated measurement range switching
Automatic maximum value identification fot the connected potentiometer
Specifications
Notes
| Safety Information | Input and output must be safely isolated from any hazardous live parts! |
| Note | Use shielded signal cables!Only use shielded signal cables for analog input and output signals.This ensures the device maintains its specified accuracy and immunity to interference, even when external disturbances affect the signal cable., Additional setting options via the WAGO Interface Configuration Software |
