Siemens 6ES7133-6BH00-0BA0 SIMATIC ET 200SP DI8x/DQ8x 24V DC/0.5A ST Remote I/O Module

The Siemens 6ES7133-6BH00-0BA0 is a SIMATIC ET 200SP digital combined module providing 8 inputs and 8 outputs at 24 V DC, with outputs rated 0.5 A each in standard (non-high-speed) mode. Inputs are sinking (P-reading) type and outputs are PNP source, both parameterizable, with substitute-value output on the DQ side and module-wise diagnostics for short circuit and wire break.

Selection Notes

This is the standard-speed combined I/O module, at 100 Hz max switching frequency on resistive loads, versus separate dedicated DI-only or DQ-only ET 200SP modules; picking it over two single-function modules saves a slot when a station needs both input and output points but not high channel counts on either side. Outputs support parallel switching of two channels for redundant load control, which the equivalent single-type module may not offer the same way. Wire-break diagnostics on the inputs can be tuned with an optional 25-45 kOhm protective circuit for simple encoder contacts that would otherwise false-trigger the diagnostic.

Applications

Fits ET 200SP stations needing a compact mixed I/O point, such as sensor inputs paired with valve or indicator outputs on a single machine section, or as a low-channel-count expansion slot where a full 8-input or 8-output module would be underused.
