Item description

Short description:

The Potentiometer Position Signal Conditioner records resistance signals (e.g., from potentiometers), and converts them into standard analog
signals. The device is supplied with 24 VDC (nominal voltage). It is set via DIP switches or push and slide switches.

Features:

PC configuration interface

Calibrated measurement range switching

Automatic potentiometer identification

Safe 3-way isolation with 2.5 kV test voltage per EN 61140

Note:

Additional setting options via interface configuration software or interface configuration app
