Siemens 6ES75221BH010AB0 — SIMATIC S7-1500 16-Channel Solid-State Digital Output Module
Overview
This module installs on a DIN rail within a SIMATIC S7-1500 rack and provides 16 solid-state output channels for switching 24 V DC loads in industrial control cabinets. The catalog entry lists 16 solid-state outputs, an operating range of 30 °C to 60 °C, DIN Rail mounting, and ROHS3 compliance; output voltage, per-channel current rating, and isolation values are not present in the supplied fields.

- Power dissipation -Dimensions and weight
Integration / Installation Notes
The unit mounts on a DIN rail as part of a SIMATIC S7-1500 PLC system. Load wiring, bus connector, and fusing details are not specified in the supplied fields. The solid-state output type implies no moving contacts, which affects load compatibility (lamps, solenoids, contactors) compared to relay outputs; verify against the datasheet whether flyback diodes or other load-side protection are required.
Selection / Substitution Guidance
The alternate 6ES75221BH100AA0 shares identical spec values and appears to be a same-family variant; substitution is plausible but must be verified against the datasheet to confirm pinout, address settings, and firmware compatibility. Modules with different output counts (64-channel variants 6ES75221BP000AA0, 6ES75221BP500AA0) are not direct substitutes. The 8-relay variant 6ES75225HF000AB0 uses a different output technology (relay vs. solid-state), which changes load-handling characteristics and lifecycle behavior.

Why they are similar:
- 6ES75221BH100AA0 matches on output count (16), output type (solid-state), series, mounting, operating temperature, and encapsulation; both carry the same ROHS3 and Active status. The data source does not indicate what distinguishes the -010AB0 suffix from the -100AA0 suffix; consult the datasheet for firmware, address switch, or labeling differences.
- 6ES75221BP000AA0 shares the same series, solid-state technology, and DIN Rail mounting, but scales to 64 channels and ships in a Box package rather than Bulk; the expanded output count changes backplane current draw and may require a different power budget.
- 6ES75225EH000AB0 matches on 16 solid-state outputs and S7-1500 compatibility, but lists a wider voltage range (24–48 V AC/125 V DC) and operates from 0 °C rather than 30 °C; it is not a drop-in replacement without confirming voltage and address compatibility.
FAQ
Q: What supply voltage does the 6ES75221BH010AB0 require? A: The catalog entry does not include a supply voltage field. The title references 24 V, but this must be verified against the official Siemens datasheet for the SIMATIC S7-1500 DQ 16×24 V DC module before finalizing the power budget.
Q: Can 6ES75221BH100AA0 substitute for 6ES75221BH010AB0? A: The two share identical spec values and similarity 1.0 in the data source. Whether the suffix difference affects address configuration, firmware, or mechanical fit must be confirmed with the datasheet and engineering review.
Q: Does this module include short-circuit protection? A: The supplied fields do not contain a protection or breaking-capacity entry. Selection must not proceed on assumptions; refer to the Siemens equipment manual for solid-state output protection characteristics.
