Key Functional Characteristics
The GE 820-0445/00 provides deterministic digital signal handling for both monitoring and actuation tasks. Input circuits are designed to reliably detect field contact states, while output stages drive relays, alarms, or breaker control circuits with stable current delivery.
Built-in diagnostics assist maintenance personnel by identifying channel faults or abnormal operating conditions early, reducing troubleshooting time and improving overall system availability.
Typical Application Scenarios
In power plants, this PCB is commonly used for turbine auxiliary controls, protection interlocks, and alarm signaling. Within substations, it supports transformer status monitoring, breaker position feedback, and command outputs. The card is also suitable for industrial control panels where GE Energy Control System hardware is deployed.
Compatibility Notes
The GE 820-0445/00 is intended exclusively for use within compatible GE Energy Control System racks and backplanes. It is not designed for standalone operation. Proper grounding, wiring segregation, and adherence to GE installation guidelines are required to maintain signal integrity and operational reliability.
FAQ
Q: Can the GE 820-0445/00 be used as a standalone I/O module?
A: No. This PCB is designed to operate only within a GE Energy Control System chassis and relies on system backplane communication and power distribution.
Q: Are input and output channels configurable?
A: Channel behavior is defined by the host control system configuration and application logic rather than local hardware switches.
Q: Is this board suitable for retrofit projects?
A: Yes, provided the existing system supports the 820-0445/00 form factor and electrical interface requirements.
