Siemens 6ES75221BH010AB0 — SIMATIC S7-1500 Solid-State Output Module
Catalog Context and Output Family
The 6ES75221BH010AB0 is a 16-channel solid-state output module in the Siemens SIMATIC S7-1500 series. The "6ES7" prefix denotes the Siemens automation catalog family; the "521" digit pair identifies the DQ (digital output) function block. This module ships in bulk packaging and mounts on DIN rail within an S7-1500 rack.
Key Specifications
| Parameter | Value |
|---|---|
| Series | SIMATIC S7-1500 |
| Number of Outputs and Type | 16 — Solid State |
| Mounting Type | DIN Rail |
| Operating Temperature | 30°C to 60°C |
| Encapsulation / Package | Bulk |
| For Use With/Related Products | SIMATIC S7-1500 |

Solid-state construction implies no moving contacts in the output stage, which affects current-switching life characteristics compared to relay outputs.
Functional Characteristics
Output Topology
The module provides 16 solid-state output points operating at 24 V. Because the records do not specify per-channel current rating or total aggregate current, those parameters cannot be quoted here.
Thermal and Environmental
Operating temperature is rated from 30°C to 60°C. This range is narrower on the cold side than some alternate S7-1500 DQ modules that start at 0°C. The 30°C lower limit should be evaluated against the expected cabinet ambient in the intended installation.
Physical Integration
- DIN Rail mounting is the sole stated mechanical option.
- The module is packaged in bulk (no individual box or tray).
- No IP rating, cutout dimension, or bus-connector detail appears in the records.
In-Catalog Comparison
The table below presents side-by-side screening of the seed and two highest-similarity catalog peers. Similarity scores are catalog-derived and do not constitute interchange approval.
| MPN | Series | Outputs | Type | Operating Temp | Encapsulation | Similarity |
|---|---|---|---|---|---|---|
| 6ES75221BH010AB0 | S7-1500 | 16 — Solid State | SS | 30°C~60°C | Bulk | — |
| 6ES75221BH100AA0 | S7-1500 | 16 — Solid State | SS | 30°C~60°C | Bulk | 1.00 |
| 6ES75221BP000AA0 | S7-1500 | 64 — Solid State | SS | 30°C~60°C | Box | 0.96 |
Why These Are Catalog-Peers
- 6ES75221BH100AA0 shares identical output count (16), output technology (solid-state), thermal band, and bulk packaging. The MPN edit similarity and shared parameter set make it the closest in-catalog match; the "BH1" versus "BH0" mid-prefix variation suggests a minor variant, but the reason string does not disclose the functional difference.
- 6ES75221BP000AA0 extends the same solid-state S7-1500 architecture to 64 channels while retaining DIN Rail mounting and the 30°C–60°C operating window. The package shifts from Bulk to Box, and the higher channel count changes backplane current draw and slot occupation.
Lower-similarity rows include an even wider 64-channel sink variant (6ES75221BP500AA0), a 16-channel universal-voltage unit with 0°C start temperature (6ES75225EH000AB0), an 8-relay relay-output variant (6ES75225HF000AB0), and two 16-channel digital input modules (6ES75211BH000AB0, 6ES75211BH100AA0) plus a mixed DI/DQ module (6ES75231BL000AA0) that carries both input and output counts.
FAQ
What is the output current rating per channel for 6ES75221BH010AB0? The per-channel current rating is not present in the available catalog data for this MPN.
Does the 6ES75221BH010AB0 support 0°C operation? No. The stated operating temperature is 30°C to 60°C. Alternate S7-1500 DQ modules such as 6ES75225EH000AB0 offer a 0°C lower limit but differ in output count and technology.
Can the 6ES75221BH100AA0 replace the 6ES75221BH010AB0 without further qualification? The two share identical stated specs and a similarity score of 1.00, but any substitution requires the user's own engineering review per the target application's requirements.
