Features:
- Provides 12 reliable SPDT relay circuits, each monitored by an isolated contact pair to verify actual relay position rather than just the command state
- Distributes 12 outputs across 48 terminals with a low-profile design for double stacking
- Features a read-only ID chip for hardware verification. Isolated voltage feedback monitors fuse status when used with WROB/F/G option boards, generating alarms for open fuses
The IS230SRLYH2A IS200SRLYH2AAA is designed with twelve Form-C (SPDT) electromechanical relays, providing a dependable interface for discrete actuators such as solenoids and alarms. A critical advanced feature is the diagnostic capability: each relay is equipped with an isolated set of contacts separate from the load circuit. These feedback contacts allow the PDOA/YDOA I/O pack to actually verify the relay has moved to the commanded position, rather than simply confirming the output command was sent.
The board acts as a flexible platform with no fixed on-board jumpers. Instead, users plug in specific option boards to achieve the desired power distribution and fusing architecture. The WROB option converts the SRLY into a functional equivalent of a TRLY board, distributing fused and sensed power. The WROF option adds a dedicated series fuse to each relay common connection with voltage feedback, while the WROG option distributes power from a single input connector to each relay.
The IS230SRLYH2A IS200SRLYH2AAA incorporates a multi-layered diagnostic strategy. First, the I/O pack reads a dedicated ID chip on the board, which contains the board type, revision, serial number, and plug location. If a mismatch occurs, a hardware incompatibility fault is generated, preventing incorrect operation. Second, when used with WROB/F/G option boards, the system implements isolated voltage feedback to check the status of the board's fuses.
The IS230SRLYH2A IS200SRLYH2AAA GE Relay Output Board may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).

- Turbine Trip Logic & Interlocks: Controls critical Emergency Trip Valves (ETVs) and fuel/gas shutoff valves for gas and steam turbines.
- Auxiliary Equipment Control: Drives heavy-duty contactors for lube oil pumps, turning gears, ventilation fans, and large motorized valves (MOVs).
- Plant-Wide Annunciation: Outputs discrete interlock and trip alarm signals directly to master control room annunciator panels or sirens.
- Safety-Critical Systems (Mark VIeS): Executes single "De-energize to Trip" logic in safety instrumented systems (SIS), including Fire and Gas (F&G) detection and Emergency Shutdown (ESD) loops up to SIL 3 ratings.
- Ambient Temperature: -30°C to +65°C (-22°F to +149°F) [
- Precision Execution: Commands from the master controller are synchronized via IEEE 1588 (Precision Time Protocol) and delivered via IONet to trigger the relay coils almost instantly.
- Flexible Wiring: Features 48 terminal points to support the 12 independent channels. Each relay can be field-wired using either the Normally Open (NO) or Normally Closed (NC) configuration based on application needs.
- Contact Feedback Monitoring: Internal circuitry directly senses the actual physical position of the relay contacts. If a command is issued to close a relay but the contact remains open, the system immediately flags a "Command-Feedback Mismatch" system alarm.
