CP1W-MAD42 Analog I/O Expansion Unit 4AI/2AO 1/12000 | Omron

The Original New Omron CP1W-MAD42 is a 4-input, 2-output analog I/O expansion unit designed for CP series PLC systems (CP1E, CP1L, CP1H). It accepts voltage (±10V, 0-10V, 0-5V, 1-5V) or current (0-20mA, 4-20mA) signals with 1/12000 resolution, and provides two configurable analog outputs for precise control of actuators, drives, and process instrumentation. The module features photocoupler isolation between I/O and internal circuits, open-circuit detection for 1-5V and 4-20mA ranges, and a rapid 1 ms per channel conversion time.
