Description
SM 332 (4AO) — Analog I/O
Siemens · SM 332 (4AO) · 6ES7332-5HD01-0AB0
Description
CORRECTION: the inventory labeled this part "DIGITAL I/O," but the 6ES7332 order-number prefix identifies it as an SM 332 ANALOG OUTPUT module for the S7-300 PLC, not a digital I/O module. The SM 332 (4AO) provides 4 configurable analog output channels (voltage or current) for driving actuators, valve positioners, or setpoint interfaces from the S7 program.

Notes
CORRECTION FLAGGED per research brief: inventory desc says "DIGITAL I/O" but 6ES7332-5HD01-0AB0 is definitively an SM 332 4-channel analog output module (6ES7332 prefix = SM332 analog output family). Category/type/model corrected accordingly.
