Functional Description

PWB68A999207-A is a Relay Controlled Receptacle Card developed by GE. It is a part of Mark I and II control system. It serves as an interface to manage electrical power delivery to connected devices based on a relay's signal.  The core function of this card is to control the supply of electrical power to connected devices through relay contacts. The relays act as switches that open or close circuits, allowing the card to manage when power is supplied and when it is cut off.

Functionality

• The Relay Controlled Receptacle Card plays a role in managing and controlling the relay-based functions in a control system. It provides a means to interface various control devices to the Mark I and II systems, such as actuators, sensors, and other hardware elements.
• This card is responsible for managing the electrical power to the connected devices, ensuring the appropriate relay signals are sent to activate or deactivate certain components based on real-time system conditions and operator commands.
• The Pcard operates in tandem with other components of the control system, facilitating the relay switching necessary for maintaining safe and efficient operation. It controls the receptacle that receives signals from the relays, providing both power and communication pathways for critical system functions, such as safety interlocks, shutdown systems, and equipment monitoring. By ensuring that these relays are correctly activated and deactivated at the appropriate times, the card helps prevent faults and unsafe conditions in the turbine or power generation setup.

Application in Mark I and II Control Systems

• The Mark I and II control systems, developed by GE, are among the early models in GE's turbine control system lineup. These systems are designed to handle the complex behavior of both gas and steam turbines, offering precise control, monitoring, and protection functions for power generation plants. The card is integral to these systems, providing relay-controlled switching that ensures the operation of the control system is efficient and fault-tolerant.
• In the Mark I and II control systems, the  card supports the fault tolerance and redundancy requirements that are essential for power generation operations. The relay-controlled receptacle card ensures that, even in the event of a failure, the control system can continue to operate without risking damage to the turbine or the wider power plant infrastructure. The card’s ability to interface with multiple control signals and relay outputs makes it a critical element for the safety and performance of these early turbine control systems.

Frequently Asked Questions

What is PWB68A999207-A?
It is a Relay Controlled Receptacle Card developed by GE. 

How does the Relay Controlled Receptacle Card work?
The card works by using relays to control the flow of electricity to the connected receptacles. When a control signal is received, the relay switches, opening or closing the circuit to either supply or cut off power to the connected devices.

Can I control multiple devices with one Relay Controlled Receptacle Card?
Yes, many relay-controlled receptacle cards come with multiple receptacles or outlets, allowing you to control several devices simultaneously. The number of receptacles varies depending on the card's design.
