TM5ACBM01R Modicon TM5 Bus Base for PDM and Receiver Modules

The TM5ACBM01R is a grey Modicon TM5 bus base designed for compatible power distribution modules and receiver modules.

Its main function is to mount the electronic module, connect it to the TM5 bus and isolate the incoming 24 V DC I/O power segment from the left side.

This left-side isolation allows a compatible power distribution module to start a separate I/O power segment without carrying the previous field-power circuit into the new section.

TM5ACBM01R does not generate power, process I/O signals or provide Ethernet communication. It is one component of a complete TM5 slice.

Key Features

• Bus base for PDM and receiver modules
• Left-isolated 24 V DC I/O segment
• Grey TM5 mechanical coding
• TM5 power and data continuity
• DIN-rail mounting
• No address-setting switches

Typical Applications

• Starting a new I/O power segment
• Installing TM5 power modules
• Mounting TM5 receiver modules
• Distributed I/O stations
• Machine cabinet expansion

Left-Isolated I/O Power Segment

TM5ACBM01R interrupts the incoming 24 V DC I/O power segment from the module installed on its left.

A compatible power distribution module can then introduce a new externally supplied 24 V DC segment for downstream I/O modules.

The TM5 communication and internal bus connections continue through the base according to the system architecture.

Compatible Module Types

TM5ACBM01R is intended for compatible grey modules, including selected:

• TM5SPS1 power distribution modules
• TM5SPS2 power distribution modules
• Fused PDM versions
• TM5 receiver modules

The exact electronic module and terminal block combination must be verified before installation.

TM5ACBM01R vs TM5ACBM05R

TM5ACBM01R

Left-isolated I/O power segment

No address-setting switches

TM5ACBM05R

Left-isolated I/O power segment

Includes address-setting switches

Choose TM5ACBM05R only when manual module-address configuration is required by the station design.

TM5ACBM01R vs TM5ACBM11

TM5ACBM01R

Grey base

Used with PDM and receiver modules

I/O power segment isolated on the left

TM5ACBM11

White base

Used with compatible standard 24 V DC I/O modules

I/O power segment passes through

These two bus bases are not interchangeable.

Part of a Complete TM5 Slice

A complete TM5 slice normally contains:

• Bus base
• Electronic module
• Compatible terminal block

TM5ACBM01R is the bus base only. The electronic module and terminal block may need to be ordered separately.

Installation Notes

Before installation:

• Disconnect all TM5 and field power
• Confirm the electronic module reference
• Match the grey component coding
• Verify the terminal block reference
• Check the intended power-segment boundary
• Mount the base securely on the DIN rail
• Never mix incompatible component colors
• Restore power only after checking polarity and wiring

FAQ

Q1: What is TM5ACBM01R?

A1: It is a grey Modicon TM5 bus base for compatible power distribution and receiver modules.

Q2: Does it supply 24 V DC power?

A2: No. It routes system connections and supports a new externally powered I/O segment, but it does not generate 24 V DC.

Q3: What does left-side isolation mean?

A3: The incoming 24 V DC I/O power segment from the left does not pass through the base into the new section.

Q4: Does it have address-setting switches?

A4: No. TM5ACBM05R is the corresponding version with address setting.

Q5: Can it replace TM5ACBM11?

A5: No. TM5ACBM11 is a white pass-through base for standard 24 V DC I/O modules.

Q6: Is the electronic module included?

A6: TM5ACBM01R is the bus base only unless the seller specifically supplies it as part of a complete assembled slice.
