TM5SPS2 Modicon TM5 Power Distribution Module 24V DC 10A

The TM5SPS2 is a Modicon TM5 Power Distribution Module designed to supply both the internal TM5 power bus and a 24 V DC I/O power segment.

Its primary role is to introduce or renew power inside a modular TM5 I/O island.

The module can provide up to 10 A to the 24 V DC I/O power segment while generating up to 1136 mA for the internal TM5 power bus.

This dual-supply function distinguishes the TM5SPS2 from a simple field-power terminal or a standard external 24 V DC power supply.

The module is commonly installed where a growing TM5 station requires additional power capacity or where a new electrically isolated I/O power segment must begin.

The TM5SPS2 electronic module must be assembled with a compatible TM5 bus base and terminal block. It is not a complete standalone power supply and does not operate independently outside the TM5 system.

Dual Power Distribution Function

The TM5SPS2 performs two power-distribution tasks within one module.

TM5 Power Bus

Supplies the electronics of downstream TM5 modules.

24 V DC I/O Power Segment

Supplies field-side I/O circuits and connected output loads within the permitted current limit.

This dual function is the main characteristic that separates TM5SPS2 from modules that only distribute field power.

10 A I/O Power Segment

The module can provide a maximum current of 10,000 mA to the 24 V DC I/O power segment.

This power segment may serve downstream devices such as:

• Digital input modules
• Digital output modules
• Analog I/O modules
• Sensor circuits
• Relay interface circuits
• Solenoid-related output circuits

The actual usable current depends on:

• External power-supply capacity
• Downstream module consumption
• Field-load consumption
• Wiring size
• Terminal ratings
• Ambient temperature
• Installation conditions

The 10 A rating is a segment limit, not the current consumption of the TM5SPS2 itself.

1136 mA TM5 Power Bus Supply

The module generates up to 1136 mA for the internal TM5 power bus.

The TM5 power bus supplies the electronics of downstream modules rather than their external field loads.

When designing a station, calculate the total TM5 bus current required by all modules installed after the TM5SPS2.

A new PDM may be required when:

• The existing bus supply is insufficient
• Additional I/O slices are added
• The station length is expanded
• Downstream electronics exceed the available bus-current budget

Power Segment Isolation

The TM5SPS2 is used with a left-isolated bus base.

This allows the module to begin a new 24 V DC I/O power segment that is separated from the segment to its left.

This arrangement is useful when:

• Different load groups require separate protection
• High-current outputs need an independent supply
• Sensitive inputs must be separated from noisy loads
• Machine sections require independent disconnection
• Voltage-drop management is necessary

The isolation applies to the power-segment arrangement and should not be described as channel-by-channel electrical isolation.

Required Bus Base

The TM5SPS2 electronic module must be mounted on a compatible bus base.

Supported references include:

TM5ACBM01R

24 V DC I/O power-segment bus base with left isolation.

TM5ACBM05R

Left-isolated bus base with address-setting capability.

The bus base is a separate component and should be confirmed before shipment.

Required Terminal Block

The module uses the TM5ACTBM12PS 12-pin terminal block.

This terminal block provides the external power and wiring connections required by the PDM.

Before installation, confirm:

• Terminal block is included
• Bus base is included
• Terminal coding is correct
• Power conductors are correctly sized
• Polarity is correct
• Protective devices are installed

The electronic module alone is not a complete TM5 slice.

External 24 V DC Supply

The TM5SPS2 receives power from an external regulated 24 V DC source.

The external supply must be selected according to:

• Total I/O load current
• TM5 bus demand
• Startup current
• Cable voltage drop
• Branch protection
• Machine power architecture
• Applicable electrical standards

The module does not convert AC mains voltage into 24 V DC.

Not a Standalone Power Supply

The TM5SPS2 should not be described as a general-purpose 24 V DC power supply.

It does not:

• Accept AC mains input
• Generate 24 V DC from AC
• Replace a cabinet power-supply unit
• Operate independently from the TM5 system
• Provide network communication
• Control a machine program

It distributes an externally supplied 24 V DC source within the TM5 architecture.

Not a Communication Module

The TM5SPS2 does not provide Ethernet, CANopen, Sercos or other fieldbus communication.

TM5 data exchange continues through the system bus and the relevant interface or controller.

Its function is power distribution and power-segment management.

Status LEDs

The module provides LED indication for operating and fault conditions.

Run LED

Indicates power state, reset, preoperational state or normal operation.

Error LED

Indicates conditions such as low input voltage, insufficient I/O segment voltage or TM5 bus overload.

Load LED

Indicates whether the TM5 power bus is within the acceptable current range.

These indicators help distinguish power-distribution faults from communication or I/O channel faults.

TM5 Bus Overload Monitoring

The module monitors the internally generated TM5 power-bus supply.

An overload indication may occur when:

• Too many downstream modules are installed
• Total electronic current demand is too high
• A downstream module has a fault
• Wiring or assembly is incorrect
• The external input voltage is insufficient

The downstream module current budget should be recalculated before replacing the PDM.

TM5SPS2 vs External 24 V DC Power Supply

TM5SPS2

Distributes power inside the TM5 I/O system.

Supplies both TM5 bus electronics and the I/O power segment.

Requires an external 24 V DC source.

External 24 V DC Power Supply

Converts mains power into regulated 24 V DC.

Supplies the TM5SPS2 and other cabinet loads.

These products perform different functions and are normally used together.

TM5SPS2 vs TM5 Bus Interface Module

TM5SPS2

Manages power distribution.

Does not establish fieldbus communication.

TM5 Bus Interface Module

Connects the TM5 I/O island to a controller or communication network.

Does not replace the PDM when additional bus or I/O power is required.

The two module types are not interchangeable.

TM5SPS2 vs I/O Module

TM5SPS2

Provides power to downstream TM5 slices.

Digital or Analog I/O Module

Reads field signals or controls external loads.

The PDM contains no standard process input or output channels.

Expansion Planning

A TM5SPS2 may be added when:

• More I/O modules are installed
• The power bus reaches its current limit
• A separate 24 V DC load group is required
• High-current outputs need independent protection
• Long stations require power renewal
• Machine sections need separate power isolation

Its installation location should be selected using the complete TM5 power-budget calculation.
