Schneider TM5SPS2 Power Distribution Module 24V DC

TM5SPS2 – Reliable Power Distribution for Modicon I/O Systems

Why the TM5SPS2 Matters for Your Control Cabinet

Power distribution is critical for any automation setup. The Schneider TM5SPS2 module provides a dedicated 24V DC supply to both I/O channels and the TM5 communication bus. It works seamlessly with Modicon M258 and LMC058 controllers. You can use it to separate I/O power from logic power, which improves system stability.

Key Technical Specifications

Rated supply voltage: 24V DC.
I/O power segment output: 10A.
TM5 power bus output: 1136mA (maximum).
Typical current consumption: only 25mA at 24V DC.
Maximum power dissipation: 1.91W, keeping heat low.
Short-circuit protection: requires an external 10A fuse (not included).
Electrical connection: screw or spring terminal block for flexible wiring.

Additionally, the module supplies two different bus currents: 1136mA and 740mA depending on load conditions. This ensures you can match the power to your specific I/O configuration. Furthermore, the TM5SPS2 supports hot expansion without rewiring the main power feed.

Mechanical and Environmental Ratings

Housing colour: grey.
Dimensions: 12.5mm (W) x 99mm (H) x 75mm (D).
Product weight: 0.03 kg (module only).
IP rating: IP20 for protected environments.
Operating temperature:

• -10…55°C (horizontal, no derating)

• 55…60°C with derating factor

• -10…50°C (vertical installation)
  Storage temperature: -25…70°C.
  Relative humidity: 5–95% non-condensing.
  Vibration resistance: 3.5mm (5–8.4Hz) and 1gn (8.4–150Hz) on DIN rail.
  Shock resistance: 15gn for 11ms.
  Pollution degree: 2.
  Operating altitude: up to 2000m.

Installation and Mounting Guidelines

First, mount the TM5SPS2 on a standard DIN rail. Next, connect the 24V DC main power to the I/O power segment terminals. Then, the TM5 bus automatically receives power through the internal bus connector. For short-circuit protection, always install an external 10A fuse on the I/O power input.

Specifically, this module is designed for horizontal installation to maintain full temperature range. However, vertical mounting is possible up to 50°C. Therefore, always check your cabinet's cooling when placing the TM5SPS2 near high-power devices.

Compatibility and System Integration

The TM5SPS2 is fully compatible with:

• Modicon M258 logic controllers

• Modicon LMC058 motion controllers

• All TM5 digital and analog I/O modules requiring 24V DC

Moreover, it supports mixed I/O configurations. For instance, you can combine input modules, output modules, and specialty modules on the same power segment. Meanwhile, the TM5 power bus remains isolated from field power, reducing noise interference.

Frequently Asked Questions (FAQ)

1. Can the TM5SPS2 power both the bus and external sensors?
Yes. It supplies 10A for the I/O power segment, which can power sensors, actuators, and field devices. Additionally, it provides up to 1136mA for the internal TM5 bus.

2. Do I need an external fuse for the TM5SPS2?
Yes. Schneider Electric requires a 10A external fuse on the 24V DC input for short-circuit protection. The module itself does not have an internal fuse.

3. Is this module compatible with Modicon M241 or M251?
No. The TM5SPS2 is specifically designed for Modicon M258 and LMC058 systems. For M241/M251, use other TM5 series power distribution modules.

4. What happens if I exceed the 1136mA bus current?
The TM5 power bus may experience voltage drop or reset. Therefore, always calculate your total bus load before adding more I/O modules.

5. Can I replace the TM5SPS2 without shutting down the entire system?
You cannot hot-swap this module. Always disconnect the 24V DC input first. Plan replacements during scheduled maintenance windows.
