The GE IS220YDOAS1A is a safety‑rated discrete output I/O pack engineered for the Mark VIeS Speedtronic™ turbine control system. The GE IS220YDOAS1A provides up to 12 Form‑C relay outputs with 2 A contact rating, directly interfacing with TRLYS1B, TRLYS1D, and TRLYS1F terminal boards. Featuring dual redundant IONet Ethernet ports for fault‑tolerant communication and a DC‑37 pin connector for field wiring, the GE IS220YDOAS1A supports both simplex and TMR configurations. With SIL‑2 capable diagnostics, onboard LED status indicators, and rugged construction, the GE IS220DOAS1A delivers reliable switching for safety‑critical solenoid valves and turbine protection circuits.
Gas and steam turbine control – trip solenoids, hydraulic block valves, circuit‑breaker trip coils
Safety Instrumented Systems (SIS) – SIL‑rated emergency shutdown (ESD) and protection loops
Generator excitation – contactor control and field breaker actuation
Auxiliary systems – motor contactors, strobe horns, master alarm annunciators
Industrial automation – discrete on/off control in high‑reliability DCS environments
12 Form‑C relay outputs – each rated at 2 A (resistive) or 80 VA pilot‑duty, suitable for driving solenoids, contactors, and trip coils
Dual redundant IONet Ethernet – two independent 10/100BASE‑TX ports ensure uninterrupted communication during network faults
TMR‑ready architecture – supports triple‑modular redundancy with three packs installed on the same terminal board for 2‑out‑of‑3 voting
Onboard relay fuse feedback – monitors output circuit integrity and detects fuse loss for proactive diagnostics
Integrated self‑diagnostics – power‑up checks of RAM, flash memory, Ethernet ports, and processor hardware
LED status indicators – 12 yellow relay‑commanded LEDs plus 4 system status LEDs for real‑time visual diagnostics
Wide operating temperature range – –30°C to +65°C for harsh industrial environments
Conformal coating – protects against moisture, dust, and chemical contaminants
ToolboxST integration – configuration and diagnostic data accessible through GE ControlST software suite
Executes discrete output commands – converts controller logic signals into relay actuation for field devices
Provides fused output monitoring – detects open circuits and fuse failures, reporting faults to the controller
Supports redundant network communication – maintains connectivity via dual Ethernet ports; seamless failover if one path fails
Performs power‑up self‑diagnostics – verifies RAM, flash, Ethernet, and processor integrity at startup
Interfaces directly with terminal boards – plugs onto TRLY series boards via DC‑37 connector; eliminates internal cabinet wiring
Q1: What terminal boards are compatible with the IS220YDOAS1A?
A1: The IS220YDOAS1A supports TRLYS1B, TRLYS1D, and TRLYS1F terminal boards, providing flexible integration options for various relay output configurations.
Q2: Can the IS220YDOAS1A be used in a redundant configuration?
A2: Yes. The IS220YDOAS1A supports both simplex (one pack) and Triple Modular Redundant (TMR) configurations with three packs installed on the same terminal board.
Q3: What is the contact rating of the relay outputs?
A3: Each of the 12 Form‑C relay outputs on the IS220YDOAS1A is rated at 2 A for resistive loads at 24 VDC or 120 VAC, and 80 VA for pilot‑duty applications.
Q4: What diagnostics does the IS220YDOAS1A perform?
A4: The IS220YDOAS1A performs power‑up self‑tests on RAM, flash memory, Ethernet ports, and processor hardware. It also monitors relay fuse status and provides LED indications for real‑time diagnostics.
Q5: Is the IS220YDOAS1A SIL‑rated?
A5: The IS220YDOAS1A is SIL 2 capable (system‑dependent) and carries CE, UL, and CSA certifications, making it suitable for safety‑critical applications within the Mark VIeS platform.
