FUNCTIONAL DESCRIPTION:

5461-117 is a Power Supply Module - 301 manufactured and designed by Woodward as part of the 5400 Series used in Turbine Control Systems. The Woodward 5461-117 PLC (Programmable Logic Controller) is an advanced industrial control device that provides robust and reliable control for a wide range of automation applications. This PLC is specifically designed to meet the demanding requirements of power generation, oil and gas, and other industrial sectors, ensuring efficient, safe, and secure operations. A motherboard located on the back of the power supply chassis allows the two power supplies to form a redundant power system, providing six separately regulated 24 Vdc, 6 A outputs to the control. Power supplies play a critical role in ensuring the reliable operation of various electronic and electrical systems. However, to ensure safety during installation and servicing, it's essential to provide a means for disconnecting input power to each main power supply.

FEATURES OF POWER SUPPLY MODULE:

• Absence of Input Power Switches: Power supplies are designed primarily to provide a stable and consistent source of electrical power to the devices they serve. Consequently, they often lack built-in input power switches. This absence is deliberate as it prevents accidental power interruptions that could disrupt sensitive equipment.

• The Need for Disconnecting Means: In situations where maintenance, repair, or installation work is required on the power supply unit or the equipment it powers, a reliable means of disconnecting input power is essential. This ensures the safety of personnel working on the system.

• Circuit Breaker: One commonly used option for disconnecting input power is the installation of a circuit breaker that meets the specified requirements. Circuit breakers are designed to interrupt electrical currents when necessary, acting as a protective switch. They are a dependable choice for disconnecting power safely during maintenance or emergencies.

• Separate Disconnect Switch: Another viable option is to install a separate disconnect switch. This switch allows for the manual interruption of input power to the main power supply. It provides a straightforward method for isolating the power supply from the electrical source.

COMPATIBILITY:

• When redundant power supplies are in use, current sharing circuitry balances the load to reduce heat and improve power supply reliability. If one of the power supplies fails, this feature allows for the power supplies to be replaced while the control is still running.

• Each main power supply has four LEDs that indicate the health of the power supply (OK, Input Fault, Overtemperature, and Power Supply Fault). Connections to the main power supply are made via terminals on the front of the power supplies. The power supply chassis is linked to the control chassis via a 50-pin ribbon cable.

• The cable connects to the Power Supply Chassis near the back of the upper side of the Chassis. Because the Power Supply Ribbon cable is only one foot long, the TMR PS Chassis must be placed directly beneath the A or C Kernels of the TMR Main Chassis.

• To ensure safety and compliance, it is imperative that all wiring is installed in strict accordance with the wiring methods defined for Class I, Division 2 locations. Additionally, all wiring and installation procedures must align with the directives and regulations established by the authority having jurisdiction over the specific location or facility.

FREQUENTLY ASKED QUESTIONS:

How can a failed power supply be replaced without interrupting the control system?

In the event of a power supply failure, the redundant design allows for easy replacement without interrupting the control system's operation. The functioning power supply continues to power the system while the faulty one is being replaced.

How are the power supplies connected in the chassis?

The connections to the main power supplies are made via terminals located on the front of the power supply units. These terminals provide a convenient interface for connecting power input and output cables.

How is the PS chassis linked to the control chassis?

The power supply chassis is connected to the control chassis through a 50-pin ribbon cable. The ribbon cable is connected to a specific connector on the TMR (Triple Modular Redundant) Main Chassis's back underside. The cable can be attached to connectors beneath the A and C Kernels in either direction.
