TM5SPS2 Schneider Electric 24 Vdc 10 A Power Distribution Module

Product Overview: TM5SPS2 Power Distribution Module

The Schneider Electric TM5SPS2 is a power distribution module engineered for the Modicon TM5 distributed I/O platform. It performs two critical functions: supplying the I/O power segment and feeding the TM5 bus. Because the module accepts a 20.4–28.8 Vdc input range, it tolerates the voltage sag and ripple common in industrial 24 Vdc networks. Consequently, it maintains stable segment power even when upstream supplies drift.

Engineers specify this module when a TM5 slice requires a dedicated, fused power segment rather than relying on the bus supply alone. The TM5SPS2 draws only 25 mA for its own operation, so nearly all input power reaches the segment. Meanwhile, it delivers a maximum output current of 10 A per segment, which supports dense I/O configurations without an external distribution block.

TM5SPS2 Key Features and Verified Specifications

• Module type: Power distribution for I/O segment and TM5 bus supply.
• Supply voltage: 24 Vdc nominal, with a 20.4–28.8 Vdc input range.
• Maximum output current: 10 A per segment.
• Self-consumption: 25 mA from the module itself.
• Diagnostics: ModuleOK, DcOk, and segment fuse OK indicators.
• Protection rating: IP20 for cabinet installation.
• Dimensions (H×W×D): 99 × 25 × 75 mm.
• Weight: 0.05 kg.
• Operating temperature: 0 to +55 °C.
• Storage temperature: -25 to +70 °C.

The 10 A segment rating stands out in this class. It lets you power a full slice of high-density digital or analog modules from one distribution point. In addition, the three diagnostic LEDs give maintenance teams immediate visibility into module health, DC bus status, and fuse condition.

Compatibility and Integration

The TM5SPS2 integrates directly with Modicon M241, M251, M258, and LMC058 controllers. It occupies a single 25 mm slice position on the TM5 bus, so it fits compact cabinets without wasting rail space. Because the module handles both segment and bus supply, it simplifies power architecture: one input feed serves the entire downstream I/O group.

For precise electrical specifications and configuration limits, consult the official Schneider Electric datasheet. The module carries no fieldbus protocol of its own; it operates as a power layer within the TM5 assembly.

Installation Guidance

Mount the TM5SPS2 on a standard DIN rail inside an IP20-rated enclosure. Keep the 24 Vdc input within the verified 20.4–28.8 Vdc range. Route supply wiring away from high-frequency drive cables to reduce noise coupling. Since the module dissipates little heat at 25 mA self-consumption, natural convection in a ventilated cabinet suffices. Verify the segment fuse rating before energizing the I/O slice.

Maintenance and Reliability

Inspect the diagnostic LEDs periodically. A dark DcOk indicator points to input voltage loss, while a segment fuse fault suggests downstream overload. Check terminal torque and look for discoloration at the supply terminals during routine cabinet inspections. The 0 to +55 °C operating range suits most control rooms, but avoid condensing humidity near the IP20 housing.
