Siemens 6ES7232-4HD50-0XB0 SIMATIC S7-1200 SB 1232 4 AO 14-Bit Signal Board

The Siemens 6ES7232-4HD50-0XB0 is a SIMATIC S7-1200 SB 1232 signal board with 4 analog output channels on a single CPU-mounted board, each switchable between ±10 V DC, 0-20 mA, or 4-20 mA at 14-bit voltage / 13-bit current resolution. It fits a compact 15 x 62 x 63 mm footprint, weighs 28 g, and reports wire-break and short-circuit diagnostics per channel.

Selection Notes

The SB 1232 4AO packs 4 analog output channels into the CPU signal-board footprint (15 x 62 x 63 mm, 28 g) instead of a full SM 1232's rack slot, worth the tighter wiring access when panel space is the constraint rather than channel count. Unlike the single-channel SB 1232 signal board, it also supports 4-20 mA current mode in addition to 0-20 mA and ±10 V DC, matching standard 2-wire transmitter loop conventions directly. At 3 W typical power loss -- double the single-channel SB 1232's 1.5 W -- confirm the CPU's total power budget when stacking this alongside other signal boards and modules.

Applications

4-loop analog output on space-constrained panels using standard 4-20 mA transmitter loops, damper or valve positioning, or drive setpoint signals where a full SM 1232 rack module isn't justified.
