GE IS200SRLYH2AAA Simplex Relay Output Terminal Board
Product Description
GE IS200SRLYH2AAA is a simplex relay output terminal board for GE Mark VI / Mark VIe Speedtronic turbine control system. It adopts conformal coated PCB design and integrates 12 SPDT form-C relay channels. This board serves as the isolated discrete output interface between the matched VRLY I/O pack and field loads, converting control logic commands into dry relay contact signals for turbine auxiliary control and alarm circuits.
Product Functions
- Provide 12 channels of isolated SPDT relay dry contact outputs
- Switch on-site loads including solenoid valves, alarm horns and indicator lights
- Isolate the main control circuit from external field wiring and load currents
- Built-in surge suppression and protection circuits for inductive loads
- Execute trip, alarm, interlock and auxiliary equipment start-stop commands
- Work with VRLY I/O pack for discrete output logic control
Applications
- Gas turbine and steam turbine alarm and auxiliary control circuits
- Control of lube oil pumps, cooling fans and solenoid actuators
- Power plant combined-cycle Mark VIe cabinet spare replacement
- Oil & gas turbomachinery safety alarm and interlock control
- Retrofit and maintenance of legacy Speedtronic turbine control racks
FAQ
Q: Which I/O pack matches IS200SRLYH2AAA?
A: It is paired with the VRLY relay output I/O pack to receive digital control commands.
Q: How many relay output channels does it have?
A: It has 12 SPDT form-C relay channels for independent switching control.
Q: Can this board be used for TMR redundant racks?
A: This is a simplex version, not designed for TMR triple modular redundant configurations.
