The Siemens 6ES7232-0HB22-0XA0 Expansion Module (EM 232) adds two analog outputs to SIMATIC S7-200 controllers. Sold as a spare part, it is compatible only with S7-22X CPUs and provides two AO channels with a bipolar ±10 V DC range and a 12-bit converter, allowing direct voltage signaling to actuators or other analog devices from the CPU. Designed to extend the I/O options of the S7-200 family, EM 232 integrates into the S7-200 expansion lineup to deliver precise analog outputs for process control tasks.
