Description
The Schneider Electric TM5 Bus Base Modules are the foundational backbone components of the Modicon TM5 distributed I/O system, used in conjunction with Modicon M340, M580, and Premium PLCs. These base units provide the communication bus (Ethernet, CANopen, or SERCOS) and the physical mounting platform for TM5 digital/analog I/O modules, specialty modules (counter, weigh scale), and interface cartridges. Selecting the correct base—Bus Coupler Base, Expansion Base, or End Base—is essential for proper system architecture.
Key Features
- System Foundation: Forms the mechanical and electrical backbone of TM5 distributed I/O islands.
- Hot-Swap Capable: I/O modules can be replaced without powering down the entire island (requires proper configuration).
- DIN Rail Mountable: 35mm top-hat rail installation.
- Color-Coded: For easy visual identification of bus type and function.
- Interconnects via Ribbon Cable: Bases lock together; communication passes through the integral bus.
Model Descriptions & Technical Specifications
Model | Description | Function | Key Notes |
|---|---|---|---|
TM5ACBM01R | Bus Coupler Base (Ethernet / CANopen ready) | First base in island; accepts TM5 bus coupler (e.g., TM5ACSEIP-2, TM5ACCNO1) | Power & comms fed here; must be first in chain |
TM5ACBM11 | Expansion Base (Intermediate) | Accepts any TM5 I/O module; sits between coupler base and end base | Passes bus signals downstream |
TM5ACBM3FS | Fiber Optic Expansion Base (Special) | Expansion base with specific fiber-ready markings; used in extended-distance TM5 links | Check compatibility with your fiber interface cartridge |
TM5ACBN1 | End Base (Terminator) | Closes the TM5 island; contains bus termination resistor | Mandatory last module in every TM5 island |
