TM5SPS3 Modicon TM5 Interface Power Distribution Module 24V DC 10A

The TM5SPS3 is a Modicon TM5 interface power distribution module used with compatible CANopen or Sercos III fieldbus interface assemblies.

It distributes an external 24 V DC supply to the I/O power segment and provides power for the interface bus electronics.

The module supports up to 10 A on the 24 V DC I/O power segment and supplies up to 750 mA to the TM5 bus under normal horizontal installation conditions.

TM5SPS3 does not perform CANopen or Sercos III communication. The adjacent fieldbus interface module manages communication, while TM5SPS3 provides the required power distribution.

Key Features

• Interface power distribution module
• Supports CANopen interface assemblies
• Supports Sercos III interface assemblies
• 24 V DC external supply
• 10 A I/O power segment
• Up to 750 mA TM5 bus output
• Separate external fuse circuits
• Grey TM5 system coding

Typical Applications

• CANopen remote I/O stations
• Sercos III I/O islands
• Packaging machinery
• Distributed machine control
• Motion-control installations

Interface Power Function

TM5SPS3 supplies power for two separate system areas:

24 V DC I/O Power Segment

Provides field-side power for compatible downstream I/O modules and connected sensors or actuators.

Interface and TM5 Bus Electronics

Provides operating power for the compatible communication interface and downstream TM5 electronics.

It does not create or process network data.

CANopen and Sercos III Support

TM5SPS3 can be used in compatible TM5 assemblies associated with:

• CANopen fieldbus interfaces
• Sercos III interface systems
• Motion controllers
• Logic controllers

The actual network connector, address and protocol processing are provided by the compatible communication interface, not by TM5SPS3.

Output Capacity

Maximum I/O Segment Current

10 A

TM5 Bus Output

750 mA from -10 to 55°C

TM5 Bus Output with Temperature Derating

500 mA from 55 to 60°C

The total current demand of the connected electronics and field loads must remain within these limits.

External Fuse Protection

The wiring arrangement requires external time-delay fuse protection.

I/O Power Circuit

10 A maximum time-delay fuse

Internal Electronics Supply

1 A time-delay fuse

TM5SPS3 does not contain the same integrated 6.3 A fuse arrangement as TM5SPS2F.

TM5SPS3 vs TM5SPS2

TM5SPS3

Used with CANopen or Sercos III interface assemblies.

Supplies interface-bus electronics and the 24 V DC I/O segment.

Provides up to 750 mA bus current under normal conditions.

TM5SPS2

Used to renew power within a standard TM5 I/O station.

Supplies the TM5 internal power bus and the 24 V DC I/O segment.

Provides a different TM5 bus current capacity.

The two modules should not be selected only because both distribute 24 V DC power.

TM5SPS3 vs Communication Module

TM5SPS3

Distributes electrical power.

Has no independent network communication function.

Does not assign CANopen addresses or exchange process data.

Communication Interface Module

Connects the I/O island to the fieldbus.

Processes network data.

Provides the actual CANopen or Sercos III interface.

Both components may be required in a complete remote I/O assembly.

Installation Notes

Before installation:

• Disconnect all external power
• Verify the exact system architecture
• Confirm CANopen or Sercos III interface compatibility
• Calculate the TM5 bus power demand
• Calculate the I/O load current
• Install the required external fuses
• Use an isolated 24 V DC PELV supply
• Check polarity before energizing
• Do not connect the module directly to line voltage

FAQ

Q1: What is TM5SPS3?

A1: It is a Modicon TM5 interface power distribution module for compatible CANopen or Sercos III I/O assemblies.

Q2: Is TM5SPS3 a CANopen communication module?

A2: No. It supplies power to the interface assembly; the communication module handles CANopen data.

Q3: What is the maximum I/O power current?

A3: The 24 V DC I/O power segment supports up to 10 A.

Q4: How much current does it provide to the TM5 bus?

A4: It provides up to 750 mA at temperatures up to 55°C, derated to 500 mA from 55 to 60°C.

Q5: Does it include an internal fuse?

A5: The documented wiring uses external time-delay fuses rather than the integrated fuse arrangement found in fused PDM models.

Q6: Can it be used as a standalone 24 V DC power supply?

A6: No. It distributes power from an external isolated 24 V DC source.

Q7: What distinguishes it from TM5SPS2?

A7: TM5SPS3 is intended for fieldbus interface assemblies, while TM5SPS2 renews power within a standard TM5 I/O station.
