The B&R 3PS477.9 is a robust power supply module designed to meet the demanding requirements of industrial automation systems. As part of the B&R 2005 series, this module ensures reliable conversion of a 24 VDC input voltage into the necessary internal voltages required by PLC systems. Each main and expansion unit within a system requires a dedicated power supply module like the 3PS477.9 to function effectively.

This power supply module is engineered to be installed in the far-left slot of the backplane and occupies two slots, integrating seamlessly into your existing setup. It boasts an output power capacity of up to 58.5 W, with a maximum current requirement of 3.5 A, ensuring that it can handle a wide range of power demands.

One of the key features of the 3PS477.9 is its built-in expansion slave, which allows for the initiation of an additional I/O bus segment, expanding the capabilities of your control system. This feature is particularly useful for complex systems requiring extensive I/O modules and peripherals.

The module is also equipped with a series of LED indicators that provide immediate visual feedback on the operational state of the power supply, including the status of the 5 V, 24 V, and 11 V internal voltages. This diagnostic capability is invaluable for maintaining system uptime and quickly addressing any power-related issues.

For added reliability, the 3PS477.9 includes a fuse for protection against reverse polarity and overload, ensuring the longevity and safety of your equipment. The module also features a READY relay contact that can be integrated into emergency stop safety chains, providing an additional layer of operational security.

With its combination of power efficiency, expansion capabilities, and protective features, the B&R 3PS477.9 power supply module is an essential component for any industrial automation system requiring consistent and reliable power distribution.

Frequently Asked Questions

What input voltage range does the power supply module support?

The power supply module is designed to operate with an input voltage range from 18 VDC to 30 VDC, with a nominal input voltage of 24 VDC.

Can this power supply module be used in an expansion unit?

Yes, each main and expansion unit requires its own power supply module, and the 3PS477.9 can be used in both scenarios.

What is the maximum output power of the power supply module?

The maximum output power of the module is 58.5 W, which is distributed across the different voltage outputs it provides.

Does the power supply module have any protective features?

Yes, the module is equipped with a fuse to protect against reverse polarity and overload, and it also has an internal current limit for short circuit protection.

What are the LED indicators on the power supply module for?

The LED indicators on the module provide visual feedback on the operational states, such as the status of the 5 V, 24 V, and 11 V internal voltage supplies, as well as the 24 VDC input voltage.

Is there a specific slot where the power supply module must be installed?

Yes, the power supply module must always be installed in the far left slot of the backplane and occupies two slots.

What is the purpose of the 10-pin terminal block on the power supply module?

The 10-pin terminal block is used for connections such as external buffering and grounding, and it also includes contacts for the READY relay when the PLC is switched off.

How can the power supply module be integrated into a safety chain?

The contact of the READY relay, accessible via the 10-pin terminal block, can be integrated into an emergency stop safety chain.

What should be considered when configuring a system with this power supply module?

When configuring a system, ensure that the power consumption of all installed modules does not exceed the output power of the power supply module.

How does the power supply module handle situations where the connected modules require more power than it can deliver?

If the connected modules require more power than the module can provide, its internal current limitation is activated, which can cause a reset on the CPU without a preceding power failure.
