Product description

The Siemens SIMATIC S7-200 EM 235 (Part Number 6ES7235-0KD22-0XA0) is an analog expansion module designed for the S7-22X series of PLCs. It provides four analog input channels and one analog output channel, both supporting a +/-10 V DC range with a 12-bit converter for signal measurement and control.

This module is intended for use with older Siemens S7-22X CPUs, enabling basic analog data acquisition and control functions in applications such as temperature monitoring, level control, and speed regulation. It's a cost-effective solution for extending the analog capabilities of these legacy systems.
