ARR600 User Manual

The device has eight digital inputs which all share a common reference pin. The inputs are intended for general-purpose digital I/O interfacing.

Note: Digital inputs are designed for reading the status of the feeder (open, traveling, closed) and not for detecting short-duration changes.

The inputs are optically isolated and work with voltage (bipolar) levels from 5 to 60 V and this range is guaranteed to be interpreted as a logical high state. Voltage levels less than 2 V are interpreted as a logical low state.
