The digital inputs can be connected directly to the PRH module
using the SCHUNK V4-M8-M12 distributor. The distributor has the
advantage that it collects all incoming signals and carries them in a
cable. Furthermore, at each of the four M8 connection sockets of
the distributor, the 24 V DC voltage supply is available (e.g. for
sensors) and the switching condition of the connected
components can be controlled directly at the distributor via the
integrated LEDs.
