I/O Wiring Diagram

ATTENTION Determine the maximum possible current for each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current exceeds the maximum rating, the wiring could overheat, causing serious damage to your equipment. For safety reasons, we recommend an average cable size of 22 AWG. However, depending on the current load, you may want to adjust your cable size (the maximum wire size for power connectors is 2 mm).


The inputs belong on channels DI0-DI7. Please follow the diagram below in order to understand how to connect an input device into the Moxa ioLogik E1212 device:


A Dry Contact is a contact that does not provide voltage.

A Wet Contact is a contact that will provide voltage when closed.


The outputs belong on channels DIO0-DIO7. Please follow the diagram below in order to understand how to connect an output device into the Moxa ioLogik E1212 device:


Note: A “load” in a circuit schematic is a component or portion of the circuit that consumes electric power. For the diagrams shown in this document, “load” refers to the devices or systems connected to the I/O unit.
