Siemens 6ES7232-4HB32-0XB0 SIMATIC S7-1200 SM 1232 2AO Analog Output Module

The Siemens 6ES7232-4HB32-0XB0 is a SIMATIC S7-1200 SM 1232 analog output module with 2 channels, each selectable as -10 V to +10 V voltage or 0 to 20 mA current output. Voltage outputs resolve to 14 bits and current outputs to 13 bits, with a basic error limit of ±0.3% at 25 °C on both ranges.

Selection Notes

Two independently configurable channels let this module drive one voltage and one current reference simultaneously, for example a 0-10 V setpoint to one drive and a 0-20 mA signal to a positioner, without needing two separate single-range modules. The 14-bit voltage / 13-bit current resolution and ±0.3% basic error limit are adequate for standard process setpoints; applications needing tighter accuracy across temperature swings should budget for the additional temperature error specified above 25 °C. Because the current output range is fixed to 0-20 mA rather than 4-20 mA, a downstream device expecting live-zero 4-20 mA needs the offset applied in the PLC program or an external signal conditioner.

Applications

Analog setpoint output for variable frequency drives, control valve positioners, and process instrumentation loops connected to an S7-1200 CPU.
