Embedded Relay Bypass Board for Mark VIe

The GE IS200ERBPG1A IS200ERBPG1ACA Circuit Board provides automatic contact bypass for critical control paths. This board switches redundant signal lines during maintenance or fault conditions. Therefore, you can replace faulty modules without shutting down your turbine system.

Physical Dimensions and Weight Details

This circuit board measures 26.9 cm in length and 15.2 cm in width. Its total height reaches only 2.8 cm including all component tops. The GE IS200ERBPG1A IS200ERBPG1ACA Circuit Board weighs exactly 0.47 kilograms. This weight includes four high-reliability bypass relays securely mounted on the PCB.

Connector Interfaces and Component Count

You will find one 48-pin VME connector on the rear edge. The GE IS200ERBPG1A IS200ERBPG1ACA Circuit Board also features two 20-pin terminal blocks for field wiring. These terminal blocks accept 14 to 22 AWG copper wires for bypass circuits. Inside the board, a single 8-layer PCB holds one hundred seventy-two discrete components. These components include four latching relays, suppression circuits, and status LEDs.

Energy Storage and Power Characteristics

This bypass board stores minimal energy using ceramic capacitors only. It draws operational power from the 5V and 24V VME backplane rails. The GE IS200ERBPG1A IS200ERBPG1ACA Circuit Board consumes approximately 4.5 watts during normal monitoring mode. For relay latching, it draws brief 500mA pulses per operation. Consequently, you will never need to replace any internal batteries.

Bypass Relay Specifications

Four independent bypass relays handle up to 250V AC or 30V DC signals. Each relay uses latching technology that maintains state without continuous power. The GE IS200ERBPG1A IS200ERBPG1ACA Circuit Board provides low contact resistance below 50 milliohms. This low resistance minimizes signal loss through the bypass path.

Protection and Diagnostic Features

Each bypass channel includes a dedicated status feedback contact. The GE IS200ERBPG1A IS200ERBPG1ACA Circuit Board features four dual-color LEDs for channel status indication. A green LED shows normal through-path operation. An amber LED indicates active bypass mode on that channel. For safety, each relay offers 2000V AC isolation between coil and contacts.

Environmental Tolerance and Reliability Data

You can operate this board reliably from -20°C to +60°C ambient temperature. The module also withstands 5% to 95% humidity without any condensation. For long-term use, each relay supports 50,000 latching operations and maintains state during power loss.
