Industrial CM3-SP04EAO Programmable Logic Controller

CM3-SP04EAO-A is a four‑channel analog input module for CIMON’s CM3 PLC‑S family, delivering precise signal acquisition for industrial automation. Each channel accepts either a current input (0–20 mA) or a voltage input (-10 V to +10 V), all mapped to a 14‑bit ADC for fine measurement of sensor signals. The module uses screw‑terminal connectors for straightforward field wiring and integrates with the CM3 backplane to extend the analog I/O capability of the PLC‑S system. It requires an external 24 V DC power supply. Typical applications include reading 4–20 mA process sensors, voltage sensors, and other instrumentation signals in factory automation, process control, and data acquisition tasks. This CM3‑SP04EAO‑A analog input module is part of CIMON’s CM3 analog I/O lineup, designed to build compact, scalable control architectures by combining with other CM3 modules.
