Compact M12 digital module.

The Holjeron MicroBlock I/O Module for a Smart Distributed System (SDS) handles small amounts of I/O in a limited amount of space. The device provides two inputs and two outputs in a compact enclosure. Both inputs and outputs use bus power, eliminating the need to connect additional power.

Small footprint for SDS remote I/O.
Industry standard M12 connections.
Inputs and outputs use bus power, eliminating the need for separate control power.
LED indication for each input and output for easy verification of I/O state.
