Product Description
The EM 235 is an analog expansion module for SIMATIC S7‑200 systems, providing four differential analog inputs and one analog output for ±10 V DC signal ranges. Designed for use exclusively with S7‑22X CPUs, it integrates a 12‑bit converter to deliver reliable measurement and control for industrial processes such as level, pressure, and temperature transmitters with voltage output. Its compact form factor supports dense panel installations while maintaining clear wiring access. Typical applications include adding analog acquisition to small PLCs, scaling and conditioning voltage signals, and driving a single analog actuator. The module supports straightforward configuration within the S7‑200 programming environment and is suitable for retrofit and maintenance of existing S7‑200 deployments. Package contents include the EM 235 module; cabling and terminal accessories are typically supplied separately. This unit serves technicians seeking stable analog performance on legacy S7‑200 platforms where ±10 V interfacing is required.
