Siemens 6ES7131-6BH01-0BA0 DI 16x24VDC ST (6ES7131-6BH01-0BA0) CAN Electric — Industrial Automation Parts Supplier

A 16-channel digital input for the ET 200SP station

The electronic module carries 16 sinking (PNP) 24 V DC inputs that read sensors, pushbuttons, limit switches and two-wire proximity devices. It is a standard (ST) module with configurable input delay from 0.05 to 20 ms, so the same part serves both fast response and noise-filtering duties.

Mounts on a BU-type A0 base unit, not standalone

The module has no terminals of its own. It locks onto a BU-type A0 base unit (colour code CC00), which carries the push-in connections, the supply distribution and the station backplane bus. A server module closes the row at the end.

Joins the controller through an interface module

An ET 200SP station is headed by an IM 151 interface module (PROFINET PN or PROFIBUS DP). The DI module, the base units and any DQ / AI / AQ modules share the backplane and appear as distributed I/O to an S7-300 / S7-1200 / S7-1500 controller.

Data per the Siemens Industry Mall entry and the ET 200SP product information; confirm the current data sheet before wiring or configuring the module.

16 inputs in a 15 mm slice

Sixteen 24 V DC sinking inputs pack into the 15 mm ET 200SP width, so a high-density input row stays narrow and the cabinet stays compact — ideal where panel space is tight but channel count is high.

Built-in diagnostics without extra hardware

Wire-break and supply-voltage monitoring are integrated, and the module supports I&M0-I&M3 identification data, so faults are reported to the controller and maintenance gets actionable detail without adding diagnostic modules.

Current ET 200SP production module

The 6ES7131-6BH01-0BA0 is PM300: Active, the current 16-channel standard DI for the ET 200SP platform. It drops onto the same BU-type A0 base units as the rest of the station and is configured in TIA Portal from V14.

Pick by channel count and feature level: the 6ES7131-6BH01-0BA0 on this page is the current 16-channel standard DI on BU A0 (CC00); the 6ES7131-6BF01-0BA0 gives 8 channels for smaller points; the 6ES7131-6BF00-0CA0 high-feature variant adds per-channel diagnostics and isochronous mode; and every ET 200SP station still needs a 6ES7155-6AU01-0BN0 interface module (PROFINET) or a DP equivalent to talk to the controller.

Distributed I/O at the machine

Mounted in a field cabinet or on a machine, the module collects signals from sensors, pushbuttons and limit switches close to the action, then passes them to the controller over PROFINET or PROFIBUS — keeping long sensor wiring short.

Conveyor, packaging and assembly lines

Sixteen inputs cover the position, jam and safety-switch feedback of a station in one slice; the configurable input delay filters contact bounce on mechanical switches while still catching fast pulses from encoders.

Expanding an existing ET 200SP station

Because it uses BU-type A0 base units and the same backplane as sibling DI / DQ / AI / AQ modules, the 6ES7131-6BH01-0BA0 slots into an installed station to add 16 more inputs without re-architecting the rack.

Why the -6BH01 is the current module

The 6ES7131-6BH01-0BA0 is the current PM300: Active 16-channel 24 V DC standard DI; the earlier 6ES7131-6BH00-0BA0 was the prior ST variant. Both are 16-channel standard inputs on BU-type A0 (CC00), so the swap is hardware-compatible at the base-unit level.

What stays the same

The base unit (BU A0), the colour code (CC00), the 24 V DC sink input behaviour and the ET 200SP backplane are unchanged, so the wiring and the station layout carry over; reconfigure the module in TIA Portal from V14.

When to choose the -6BH01

For any new or spares requirement on a current ET 200SP station, standardise on the -6BH01. If you still maintain a legacy station built on the older -6BH00, tell us on the quote and we can advise on like-for-like sourcing.

An independent trader that states condition in writing

We are not Siemens and not a factory-authorized distributor; what we are is transparent. Every unit supplied is genuine new, and that new condition is written on every quote, never implied.

Stock you can plan a project around

Because we trade a broad Siemens inventory, the Related Siemens list on this page shows live USD list prices with EXW Hong Kong terms, and each quote states the exact quantity available so your bill of materials stays forecastable.

Export handling on one thread

Cross-border requests are routine: a single thread covers the quote, the compliance note and the dispatch arrangement, so buyers in India, Egypt, the Netherlands, Thailand, Malaysia, the Middle East and South America do not chase separate teams.

The module locks onto a BU-type A0 base unit (colour code CC00) and joins an ET 200SP station headed by an IM 151 interface module (PROFINET PN, e.g. 6ES7155-6AU01-0BN0, or PROFIBUS DP). It is configured in STEP 7 / TIA Portal from V14 (also STEP 7 V5.5 SP3, PCS 7 V8.1 SP1). The DI module, neighbouring DQ / AI / AQ modules and the server module share the BU backplane and appear as distributed I/O to an S7-300 / S7-1200 / S7-1500 controller.

• State the condition you need — only genuine new units are supplied; the new condition is written on the quote, never implied. Units from current stock ship factory-sealed.
• Prices are USD and shipments go out from Hong Kong by DHL. If your ET 200SP station also needs a base unit (BU-type A0) or a PROFINET / PROFIBUS interface module, ask for them on the same request.
