TM5ACBM15 Modicon TM5 White Bus Base with Address Setting

The TM5ACBM15 is a white Modicon TM5 bus base with integrated address-setting switches for compatible 24 V DC electronic modules.

It supports the electronic module and terminal block while carrying TM5 communication data, internal bus power and the 24 V DC I/O power segment through the station.

Its defining feature is manual address setting. This allows compatible TM5 modules to retain a configured physical address independently of their position where the system architecture supports address-based configuration.

TM5ACBM15 is not a power supply and does not increase the speed of the TM5 bus.

Key Features

• White 24 V DC TM5 bus base
• Integrated address-setting switches
• I/O power-segment pass-through
• TM5 data and bus-power continuity
• DIN-rail mounting
• Used with compatible standard I/O modules
• Part of a complete TM5 slice

Typical Applications

• Addressed TM5 I/O stations
• Digital and analog I/O slices
• High-speed counter modules
• Remote transmitter modules
• Modular machine-control cabinets

Address-Setting Function

The built-in address switches allow a compatible electronic module to use a manually assigned physical address.

This can help with:

• Module replacement
• Fixed machine configurations
• Position-independent identification
• Repeated modular machine sections
• Controlled commissioning

The address must match the controller project configuration.

Power and Data Pass-Through

TM5ACBM15 carries three system connections:

TM5 Data Bus

Transfers module communication data.

TM5 Power Bus

Supplies internal electronic-module power.

24 V DC I/O Power Segment

Carries field-side power to compatible downstream modules.

The base does not generate or regulate any of these supplies.

Compatible Module Types

TM5ACBM15 is used with selected white 24 V DC electronic modules, including:

• Digital input modules
• Digital output modules
• Mixed I/O modules
• Analog input modules
• Analog output modules
• Temperature modules
• Counter modules
• Remote transmitter modules

Compatibility must be confirmed from the assembly information for the exact electronic module.

TM5ACBM15 vs TM5ACBM11

TM5ACBM15

White bus base

24 V DC power segment pass-through

Includes address setting

TM5ACBM11

White bus base

24 V DC power segment pass-through

No address setting

The address-setting function is the main difference between these two bases.

TM5ACBM15 vs TM5ACBM05R

TM5ACBM15

White coding

Power segment passes through

Used with standard 24 V DC modules

TM5ACBM05R

Grey coding

Incoming I/O power segment isolated on the left

Used with PDM and receiver modules

Includes address setting

The two bases perform different power-segment functions and are not interchangeable.

TM5ACBM15 vs TM5ACBM12

TM5ACBM15

White base for compatible 24 V DC modules.

TM5ACBM12

Black base for compatible AC electronic modules.

Always match the base, electronic module and terminal block according to the approved color and compatibility table.

Complete TM5 Slice

A complete TM5 slice normally contains:

• TM5ACBM15 bus base
• Compatible electronic module
• Compatible terminal block

TM5ACBM15 alone does not provide digital or analog I/O channels.

Installation Notes

Before installation:

• Disconnect TM5 and field power
• Confirm module compatibility
• Record the required physical address
• Set the address before commissioning
• Match white slice components
• Verify the terminal-block reference
• Check the I/O power budget
• Mount the base securely on the DIN rail
• Confirm the project address before restoring operation

FAQ

Q1: What is TM5ACBM15?

A1: It is a white Modicon TM5 bus base with manual address-setting switches for compatible 24 V DC electronic modules.

Q2: Does it improve TM5 communication speed?

A2: No. It carries the standard TM5 data bus. Its distinguishing feature is address setting, not higher communication speed.

Q3: Is it a 24 V DC power supply?

A3: No. It passes the existing 24 V DC I/O power segment through the slice but does not generate power.

Q4: What is the difference from TM5ACBM11?

A4: TM5ACBM15 includes address-setting switches, while TM5ACBM11 does not.

Q5: Does it isolate the incoming I/O power segment?

A5: No. The 24 V DC I/O power segment passes through from left to right.

Q6: Can it be used with TM5SPS2?

A6: No. TM5SPS2 uses a grey left-isolated base such as TM5ACBM01R or TM5ACBM05R.

Q7: Are the electronic module and terminal block included?

A7: No. TM5ACBM15 is normally supplied as the bus base only.
