GE IS200TRLYH1B IS200TRLYH1BED Mark VIe Relay Output Board

Configured for relay contact execution and solenoid actuation in General Electric Mark VIe control systems, the General Electric IS200TRLYH1BED (IS200TRLYH1B Relay Output Board) provides direct physical/electrical execution. The module accommodates up to 12 plug-in magnetic relays to route switching signals and solenoid power directly across industrial field control loops.

Hardware Specifications

Backplane Bus Communication Velocity & I/O Density Scaling

The IS200TRLYH1BED optimizes high-density output switching by isolating control logic from power-level field actuation. Channel-to-channel configuration jumpers allow circuits 1 through 6 to alternate between unpowered Form-C dry contacts and fused high-voltage drive outputs. High internal trace clearance combined with dedicated onboard arc suppression protects backplane communication paths against inductive voltage spikes during rapid relay cycling.

Frequently Asked Questions

Q: How are power supplies fused across the IS200TRLYH1BED board?

A: Power input options (125 VDC, 115/230 VAC, or optional 24 VDC) feature individual jumper-selectable fuses to isolate field supply lines.

Q: Can the first six relay channels be modified for dry contact operation?

A: Yes. Relay channels 1 through 6 can be jumper-configured for either dry Form-C contact outputs or dedicated external solenoid drive lines.

Q: What onboard surge mechanisms protect against coil inductive kickback?

A: The board incorporates built-in voltage suppression circuitry directly parallel to the relay control lines to clamp transient electrical noise.

Field Installation Guidelines

Ensure main field power and controller rack power are completely de-energized before mounting the board. Fasten the board onto the cabinet baseplate or DIN mounting hardware using standard mechanical hardware. Verify that jumper blocks for channels 1 through 6 are set strictly to match either dry-contact or solenoid voltage sourcing to prevent short circuits. Land field wiring onto terminal blocks with correct polarity, ensuring fuse selection jumpers align with the connected power source (125 VDC, 115/230 VAC, or 24 VDC).
