Introduction
When a Modicon TM5-based motion control system suffers intermittent power drops or bus communication failures, the root cause often lies in inadequate power distribution. The Schneider TM5SPS3 Power Distribution Module solves this challenge by delivering a dedicated 24 V DC supply to both I/O modules and the CANopen or Sercos III bus, ensuring stable operation even in demanding industrial environments. This module is part of the Modicon TM5 family and is designed for use with Modicon LMC078, LMC058, and M258 controllers.
Technical Specifications Breakdown
The TM5SPS3 provides a [Us] rated supply voltage of 24 V DC. It supplies up to 750 mA for the TM5 power bus at ambient temperatures from -10 to 55 °C, and 500 mA from 55 to 60 °C. For the I/O power segment, it delivers 10 A. The module consumes less than or equal to 25 mA from the 24 V DC supply. Maximum power dissipation is 1.91 W. Short-circuit protection is provided by a 10 A external fuse. The module carries CE marking and complies with standards including CSA C22.2 No 213, CSA C22.2 No 142, IEC 61131-2, and UL 508. Certifications include GOST-R, C-Tick, CSA, and cULus. Operating ambient air temperature ranges from -10 to 55 °C without derating (horizontal installation), 55 to 60 °C with derating factor (horizontal installation), and -10 to 50 °C (vertical installation). Storage temperature ranges from -40 to 70 °C. Relative humidity is 5 to 95 % without condensation. Operating altitude is 0 to 2000 m; storage altitude is 0 to 3000 m. Vibration resistance is 1 gn at 8.4 to 150 Hz on DIN rail and 3.5 mm at 5 to 8.4 Hz on DIN rail. Shock resistance is 15 gn for 11 ms. It withstands electrostatic discharge of 4 kV contact and 8 kV air per EN/IEC 61000-4-2, electromagnetic fields of 10 V/m from 80 to 2000 MHz per EN/IEC 61000-4-3, fast transients of 2 kV on power lines per EN/IEC 61000-4-4, and surge of 1 kV common mode per EN/IEC 61000-4-5. It also meets CISPR 11 for radiated/conducted disturbances.
Industry Applications
In packaging machinery, the TM5SPS3 powers I/O modules that monitor sensor inputs and control actuators, while simultaneously supplying the CANopen bus that coordinates multiple servo drives. This eliminates the need for separate power supplies and simplifies wiring. For material handling systems using Sercos III, the module ensures clean, regulated power to the motion bus, reducing jitter and improving synchronization. The module's wide operating temperature range (-10 to 55 °C without derating) suits unheated factory floors or enclosed cabinets.
Installation & Setup Guidance
Mount the TM5SPS3 on a standard DIN rail. Connect the 24 V DC supply to the input terminals. Use a 10 A external fuse for short-circuit protection as specified. Ensure the module is placed in a horizontal orientation for full current capacity up to 55 °C. For vertical installation, derate to 50 °C maximum ambient. The module automatically distributes power to adjacent I/O modules via the TM5 power bus. No additional configuration is required.
Maintenance & Reliability
The TM5SPS3 is designed for long-term, maintenance-free operation in clean, dry environments. Periodically inspect the module for dust accumulation or loose connections. The module's robust electromagnetic compatibility (EMC) performance reduces the risk of nuisance faults in electrically noisy environments. The 10 A external fuse protects against overcurrent conditions, preventing damage to downstream modules.
Compatibility & Integration
The TM5SPS3 is compatible with Modicon LMC078, LMC058, and M258 logic and motion controllers. It works with both CANopen and Sercos III network types. The module supplies 24 V DC to I/O modules and the bus, making it a central component in any Modicon TM5 system.
Selection Guide & Purchasing Advice
Before purchasing the TM5SPS3, verify that your system uses Modicon TM5 I/O modules and that your controller (LMC078, LMC058, or M258) supports CANopen or Sercos III. Ensure your 24 V DC power supply can provide the total current required by the module and all connected I/O modules. SpareTechPLC offers this module with fast shipping and expert support.
