Digital input (IO-1)

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

Digital output (IO-1)

The digital output of the device is optically isolated and can be used for controlling
low current external devices. The output is a CMOS relay which is protected by a
