Product details

Module identity and key figures

The Siemens 6ES7133-0BH01-0XB0 is an ET 200S digital I/O module combining 8 inputs and 8 outputs on a single unit, rated for 24 V DC control and carrying an I²t specification of 0.05 A²·s with starting current inrush — a detail that supports fuse coordination on the output side. The backplane communication runs at up to 12 Mbit/s, and the module includes RUN and bus fault (BF) LEDs, plus SYNC and FREEZE capabilities for deterministic update schemes.

Rating meaning and installation constraints

Output currents are derated by installation orientation: the module delivers a maximum of 2 A per output when mounted horizontally up to 60 °C; that limit drops for vertical or other positions, so plan air flow accordingly. The I²t figure (0.05 A²·s) is useful when designing output-circuit protection — it gives a guideline for the let-through energy the semiconductors can withstand during short-duration inrush events. Input thresholds follow standard 24 V logic: signal "0" spans -30 to +5 V, signal "1" spans 13 to 30 V, with a typical sink current of 4 mA at rated voltage. Maximum cable length for unshielded wiring is 100 m, and the module supports 2-wire proximity sensors directly.

Frequently asked questions

What does the I²t rating of 0.05 A²·s mean for this module?

The I²t value of 0.05 A²·s (with starting current inrush) indicates the thermal energy the module's output semiconductors can handle during short-circuit events. Use it to select upstream protective devices that limit let-through energy below this threshold.

Can the 6ES7133-0BH01-0XB0 replace the SIPLUS variant 6AG1123-2DB03-2AX0?

Electrically they are identical (same I/O count, same 24 V DC ratings), but the SIPLUS version adds wider temperature range and conformal coating. If the installation environment does not require those extras, the standard module is a drop-in replacement for the base function.

What is the maximum output current per channel?

Each digital output can handle up to 2 A for resistive loads, but that figure is only valid for horizontal mounting up to 60 °C. Derating applies for other orientations or higher ambient temperatures.
