The optionally available I/O communication module (e.g. as part of the EXTENDED package of the EasyNOₓ) provides the EasyNOₓ with analog and binary inputs and outputs. Depending on the application, these inputs and outputs can be assigned differently, for example for the input and output of measured values or for signaling warnings, errors, or certain operating states from or to a master control. Up to two I/O communication modules can be connected to the EasyNOₓ via the CAN bus interface CAN1.
For more information on the I/O communication module, read the section I/O Communication Module.
