Siemens 6ES7235-0KD22-0XA0 Analog Input Module

Siemens 6ES7235-0KD22-0XA0 is an EM 235 analog I/O module for the SIMATIC S7-200 family, designed specifically for S7-22X CPUs. It provides four analog inputs and one analog output with 12-bit conversion, supporting DC voltage and DC current measurements within a ±10 V input range and a ±10 V output range. Each voltage input channel has a 30 V destruction limit, and each current input channel has a 32 mA destruction limit, protecting the module in fault conditions. The EM 235 is powered from the backplane’s 5 V DC supply and typically consumes about 2 W. This module extends analog sensing and actuation in compact S7-200 installations where four simultaneous analog measurements plus a single analog output are required on a single EM235 card, offering precise resolution and straightforward integration with S7-22X CPUs.
