OMRON NX1W-MAB221 Analog I/O Option Board for PLC

The OMRON NX1W-MAB221 (NX1W-MAB221) is an analog I/O option unit designed for programmable logic controller (PLC) systems. Engineered to expand the analog capabilities of compatible automation controllers, this unit provides dedicated input and output channels directly on the host controller. It features two analog inputs and two analog outputs operating over a 0 to 10 V signal range, allowing direct connection to industrial field equipment. This option board supports signal conversion and integration with sensors, measuring devices, and analog-controlled actuators such as drives and valves. By reading standard voltage inputs from field instrumentation and generating analog outputs for command signals, the unit provides accurate process monitoring and control across factory automation applications. Its compact option-board format mounts securely onto the controller to optimize control cabinet space, making it an efficient choice for machine builders and automation panel installations.
