Backplane Power Distribution Characteristics

The module supplies 5.1 VDC to the Modicon Quantum backplane with a maximum output current of 8 A. Its summable power supply configuration allows operation with compatible Quantum power modules to increase available backplane current. Internal protection circuits supervise output overvoltage and overload conditions, while a normally closed alarm contact provides external indication of power supply faults. Status indication is available through the front-panel PWR OK LED.

Frequently Asked Questions

Q: Does this module support redundant or summable power operation?
A: Yes. The specification identifies the unit as a summable power supply module, allowing compatible Quantum power supplies to share backplane power capacity.

Q: What occurs during a power supply fault?
A: The module provides a normally closed alarm relay rated at 6 A, 220 V that changes state when a power supply fault is detected. Internal protection also monitors overload and overvoltage conditions.

Q: Is hot replacement specified in the provided documentation?
A: No. The supplied documentation does not specify hot-swap capability. Module replacement should follow the maintenance procedure defined for the Modicon Quantum platform.

Field Installation Guidelines

• Verify that the incoming supply remains within the specified 20...30 VDC input range before energizing the module.
• Install the specified 5 A slow-blow input fuse to provide input circuit protection.
• Confirm correct seating of the module in the Quantum backplane before applying power.
• Separate power wiring from high-noise motor or switching cables where practical.
• Connect protective earth according to the system grounding practice to minimize electrical interference.
• Confirm the PWR OK LED indicates normal operation after system startup.
• When using multiple summable power supplies, verify total backplane current requirements before commissioning.
