Description
Bachmann LM201 | M200 PLC Dummy Filler Module
Product Introduction
Not every module in a PLC rack performs a control function. The Bachmann LM201 is a purpose-built dummy module for the M200 control system, used to fill an unused slot and protect the backplane. Bachmann’s official datasheet explicitly states that the LM201 contains no electronic components.
This makes the LM201 a mechanical and protective system component—not an I/O card, processor, or communications module. It is typically relevant when maintaining an existing M200 rack, preserving unused slots for future expansion, or replacing a missing filler module. The official order number is 00009494-00.

Global Sourcing & Incoming Inspection SOP
The is a passive filler module, so acceptance focuses on correct identification, mechanical condition, and fit. It should not be subjected to powered I/O testing.
5.1 Inbound Verification
- Photograph the module and all visible markings.
- Confirm the model is .
- Check the order number, where marked, against 00009494-00.
- Inspect the housing for cracks, deformation, or damaged retaining features.
- Check the module’s insertion surfaces and mechanical guides.
- Confirm that the supplied item is a dummy module, not an active card.
- Record supplier, condition, serial or lot information if available, and quantity received.
5.2 Mechanical Fit Check
- Confirm the intended rack is part of the Bachmann system.
- Compare the ’s mechanical profile with the rack’s available slot.
- Inspect the backplane area for damage or contamination before installation.
- Verify that the module seats correctly without excessive force.
- Confirm that retaining or locking features engage as designed.
- Do not modify the filler module or rack to force a fit.
5.3 Final Preparation
- Record the inspected model and order number.
- Photograph the module before packing.
- Protect the module’s insertion surfaces and housing from impact.
- Use suitable packaging to prevent deformation during transit.
- Clearly identify the item as a dummy/filler module, not an active PLC function card.
Field Engineer’s Pitfall Guide
❗ The is not an active PLC module
The contains no electronics and provides no processing, I/O, or communication function. Do not list or install it as an operational PLC card.
❗ Verify the rack fit
The is documented for the Bachmann control system. Do not assume mechanical compatibility with other Bachmann families or unrelated PLC racks based on appearance alone.
❗ Do not apply power or perform signal tests
The is a passive filler module. Its acceptance criteria are correct identification, physical condition, and proper fit—not energized functional performance.
Intent-Driven FAQ
What is the Bachmann ?
The is a Bachmann dummy module used to fill an unused slot and protect the backplane.
Does the contain electronic components?
No. Bachmann’s official datasheet states that the contains no electronics.
What is the Bachmann order number?
The official order number is 00009494-00.
Is the an I/O module?
No. It has no I/O channels or signal-processing capability. It is a filler module.
Does the require a power supply or configuration?
No independent operating power or application configuration is identified for this passive dummy module.
Is the obsolete?
Current lifecycle status was not independently established. Bachmann continues to provide an official datasheet, but that alone does not confirm current production or stock availability. Check with Bachmann or an authorized channel for lifecycle and supply status.
What should I verify before buying?
Confirm the model, order number 00009494-00, rack compatibility, physical condition, and whether the listing is for the filler module alone.
Bottom Line for Buyers
The Bachmann (00009494-00) is a passive dummy module intended to fill one unused slot and protect the backplane. It does not provide PLC processing, I/O, or communications.
For procurement, verify the exact model and mechanical fit. A visual inspection and fit check are the relevant acceptance steps; powered functional testing is not applicable to this module.
