  • Description

The Siemens 6ES7231-4HA30-0XB0 is a SIMATIC S7-1200 signal board (SB 1231) adding one analog input channel, selectable for +/-10 V, +/-5 V, +/-2.5 V voltage ranges or 0-20 mA current, with 11-bit plus sign resolution. It plugs directly into the CPU housing without using rack space, wired through a required front connector.

Selection Notes

One parameterizable channel covering both voltage (+/-10 V down to +/-2.5 V) and 0-20 mA current inputs lets this board read a single transmitter without dedicating a full analog expansion module to it, which matters on S7-1211C/1212C CPUs with only one signal-board slot. Pick a multi-channel analog input module instead once the panel has more than one analog signal to bring in, since this board's 11-bit-plus-sign resolution and single channel are sized for adding one measurement point, not a full analog I/O bank.

Applications

Reading a single analog transmitter or sensor (0-10 V, 4-20 mA loop within the 0-20 mA range, or a smaller +/-2.5/5 V signal) directly into a compact SIMATIC S7-1200 CPU without adding an expansion module.
