Schneider TM5SPS2 Power Distribution Module

Modicon TM5 24VDC I/O Power Distribution Module (ДПМ)

It belongs to Шнайдер TM5 distributed remote I/O series, compatible with M258 / LMC058 controllers. It supplies power to the TM5 backplane bus, and provides segmented 24V field power for I/O modules. It isolates different I/O power domains and expands backplane power capacity.

✅ Основные функции

1. Источник питания for TM5 internal power bus: Макс. output 1136mA (≤55°С); 740мА (55~60°С)
2. I/O field power segment: 24В постоянного тока, Макс. 10А, to supply field side of DI/DO/AI/AO I/O modules on the right side of this base
3. Segmented power isolation: A full TM5 station can be divided into multiple independent 24V I/O power domains. Short-circuit on one segment will not shut down the entire bus.
4. Diagnostic status bits for bus: Bus OK / power warning, I/O data valid, readable via PLC program.

⚠️ TM5SPS2 vs TM5SPS2F (Key Selection Guide)

TM5SPS2: External fuse required, max 10A for I/O segment

TM5SPS2F: Built-in 6.3A fuse, I/O segment limited to 6.3A, no external fuse needed

📌 Типичные применения

Упаковочное оборудование, обработка материалов, machine tool distributed remote I/O islands. Deploy TM5SPS2 for backplane power shortage or segmented protection for sensor/actuator power.

🛠️ Troubleshooting Guide

1. Bus warning bit triggered: Check 24V voltage drop, перегоревший предохранитель, overload or short circuit in I/O segment
2. Module no communication: Verify TM5 bus connector, base address and module ID recognition
3. No field power to I/O modules: Check external 24V input at PS2 terminals and external fuse status

Примечание: All 0V connections must be tied together and connected to Functional Earth (FE) to meet EMC requirements. Only PELV safety extra-low voltage power is permitted; mains AC voltage cannot be directly connected.

📎 Альтернативы & Сравнение серий

TM5SPS1: I/O power segmentation only, no TM5 backplane bus power supply

TM5SPS2F: Same function with built-in 6.3A fuse

TM5SBER2: TM5 remote I/O receiver module with integrated bus power supply

Schneider TM5SPS2 Wiring Instructions

TM5SPS2 must be used with TM5ACTB12PS (12-pin spring terminal block). The terminal block snaps under the TM5ACBMxx bus base, and the electronic module plugs onto the base. Terminal numbers are printed on the terminal block.

1. Определение терминала (12-pin TM5ACTB12PS)

✅ Quick distinction between two power rails:

PS1 (Pin1/2) = TM5 backplane bus power; PS2 (Pin5/6) = I/O field load power. Two separate 24V supplies can be used for isolated power segmentation.

2. Two Typical Wiring Schemes

Схема 1: Single 24V Power Supply (Стандартный)

+24V from power supply is split into two branches: one through 1A T-fuse → Terminal 1; another through 10A T-fuse → Terminal 5

Power 0V: Tie Terminal 2 and Terminal 6 together, connect to power supply 0V. Link 0V to Functional Earth (FE) for EMC compliance.

Примечания: Bus power and I/O power share the same source. Short circuit on I/O side will not directly damage the bus, but the power supply capacity must cover both backplane and I/O loads.

Схема 2: Two Independent 24V Supplies (Isolated Segmentation, Рекомендуется)

PS1 (Pin1/2): Independent 24V supply with 1A slow-blow fuse, dedicated for TM5 backplane bus

PS2 (Pin5/6): Separate 24V supply with 10A slow-blow fuse for sensors and actuators of right-side I/O modules

The 0V of the two power supplies must be interconnected and connected to FE functional earth

Преимущество: Short circuit in I/O circuit will blow only the PS2 fuse, while TM5 backplane bus remains online. Suitable for high-reliability machines.

3. Спецификация провода (Весенний терминал)

Wire gauge range: 0.08 ~ 2.5 мм², рекомендуется:

Main power cable: 0.75~1,5 мм²

Low-current signal: 0.5 мм²

Wire temperature rating ≥80°C, stripping length approx.8mm

4. LED Indicator Definition (On Module Body)

E Fault LED:

Мигает: Low bus voltage / insufficient PS1 voltage / bus overload. Common field mistake: only PS2 (Pin5/6) wired while PS1 (Pin1/2) is missing → E LED blinks.

Горит постоянно: PS2 I/O power segment fault, overload or short circuit

RUN LED: Горит постоянно: Module healthy; ВЫКЛЮЧЕННЫЙ: No module power or bus fault

5. Critical Safety & Запреты на проводку
6. ❌ No built-in fuse! External Type T slow-blow fuse is mandatory for PS2 (max 10A). PS1 requires 1A slow-blow fuse. Module damage may occur without proper fusing in short-circuit events.
7. ❌ No reverse polarity protection. Never swap +24V and 0V; reversed polarity will permanently damage TM5SPS2.
8. ❌ Only PELV/SELV safety isolated 24VDC power supplies are allowed. Mains AC cannot be connected directly.
9. ❌ Do not wire NC unused terminals (3,4,7~12) to prevent accidental short circuits.
10. ✅ EMC mandatory requirement: All 0V tied together and connected to FE functional earth; FE shall not be confused with protective earth PE.
11. ✅ Current derating: ≤55°C ambient for full backplane 1136mA; reduced to 740mA for 55~60°C.
12. Pre-power-on Wiring Check List
13. Confirm PS1 (Pin1,2) 24V is connected; do not only wire PS2 (Pin5,6)
14. Verify Type T slow-blow fuses with correct ratings
15. All 0V commoned and bonded to FE
16. Terminals fully clamped, no loose connection or exposed copper strands causing short
17. Measure before power-up with multimeter: 24VDC between pin1-2; 24VDC between pin5-6, correct polarity
18. Configuration Notes (Machine Expert / SoMachine)

When the module is inserted into the base, software recognizes Module ID:7104. Status words available:

DcOk: Boolean flag for valid bus power

Bus power warning bit: Low voltage pre-alarm, usable for PLC alarm programming
