I/O modules

The GE IS200SRLYH2AAA functions as a specialized printed circuit board within the Mark VI Speedtronic series for gas and steam turbine control applications. This board provides critical relay interface capabilities, enabling the control system to switch external devices and status signals reliably. Engineers select the IS200SRLYH2AAA for turbine control panels requiring robust signal routing and isolation.

Relay Interface and Signal Processing Capabilities

We design the GE IS200SRLYH2AAA with multiple relay channels for driving external annunciators, solenoids, and indicator lamps in turbine control applications. This PCB interfaces directly with the Mark VI control backbone, receiving commands from the main processor and providing dry contact outputs for field device control. Additionally, the board incorporates status feedback monitoring for comprehensive system diagnostics.

• Relay Channels: Multiple industrial-grade relays for switching external loads.

• Contact Type: Dry contacts for isolation from control logic circuits.

• Interface: Direct connection to Mark VI backplane for command and status signals.

• Diagnostics: Feedback monitoring for relay coil and contact verification.

• Compatibility: Designed specifically for GE Speedtronic Mark VI systems.

Physical Specifications and Construction Features

The IS200SRLYH2AAA measures standard Mark VI board dimensions for direct insertion into turbine control cabinets. This printed circuit board features multi-layer construction with high-temperature FR4 substrate for reliable operation in power generation environments. Gold-plated edge connectors ensure corrosion-resistant contacts and maintain signal integrity over extended service life. Board-mounted indicators provide visual confirmation of relay states during troubleshooting.
