GE IS220YDOAS1A Digital Output Module

Global Safety Approvals: Certified for Class I, Division 2, Groups A-D (US & CAN) and Class I, Zone 2, Group IIC (ATEX/global), meeting UL, CSA, EN 60079 series, and ANSI/ISA-12.12.01 standards.

Equipment Markings: US & CAN Class I Div 2 marking "Class I, Div 2, Groups A, B, C, D, T4"; US & 

CAN Zone 2 marking "Class I, Zone 2, AEx nA nC IIC T4, Ex nA nL IIC T4 Gc X"; ATEX Zone 2 marking 

"Ex ic nA IIC T4 Gc".

Intrinsic Safety Support: Compatible with intrinsically safe ("ic") accessory terminal boards, enabling 

safe operation in explosive atmospheres.

Electrical Performance

Power Supply: 27.4–28.6 V DC input, 0.71 A max current, compatible with standard industrial power 

configurations for hazardous locations.

Contact Outputs: Supports resistive and inductive loads, with 30 V DC max voltage and 5 A DC max 

current (for TRLY_1F/2F terminal boards), adapting to diverse field actuator requirements.

Accessory Compatibility: Works with 4 types of terminal boards (IS200TRLYS1F, IS200TRLYS2F, 

IS400TRLYS1F, IS400TRLYS2F), offering flexible wiring and load adaptation options.

Temperature Range: -30 to +65 °C (-22 to +149 °F), operating reliably in extreme cold and high-

heat industrial conditions.

Mechanical Resilience: Withstands vibration (1 mm peak-to-peak, 5–16 Hz; 0.5g, 16–150 Hz) and 

shock (10g ½ sinewave, 11 ms), suitable for rugged on-site installations.

Contaminant & Humidity Resistance: Complies with ISA-S71.04 Class G3 for airborne contaminants 

and operates in 5–95% RH (non-condensing), resisting corrosive gases and moisture.

Robust Safety & Compliance

Multi-Standard Certification: Eliminates regional compliance barriers, enabling deployment in global projects across oil & gas, chemical, and power industries.

Safe Operational Design: Cannot be hot-swapped with system power energized in hazardous areas 

(unless confirmed non-hazardous), minimizing ignition risks.

Intrinsic Safety Compatibility: Works with approved intrinsically safe terminal boards, extending 

application scope to high-risk explosive zones.

Flexible Integration & Versatility

Accessory Compatibility: Supports 4 types of terminal boards (TRLYS series), adapting to Barrier-

type terminal blocks with specified wire sizes (22–12 AWG) and screw torques (9.6 in-lb/1.1 Nm).

Mark VIeS Ecosystem Integration: Seamlessly integrates with GE’s Mark VIeS SIS, enabling unified 

control, monitoring, and diagnostics for safety instrumented functions (SIFs).

Load Adaptability: Handles both resistive and inductive loads, compatible with industrial actuators 

such as solenoid valves and relays in safety loops.

Industrial-Grade Durability: Reinforced design resists environmental stressors (vibration, shock, 

contaminants), ensuring long-term stability in demanding conditions.

No User-Serviceable Parts: Sealed construction eliminates on-site calibration or disassembly, 

reducing maintenance workload and human error.

Stable Output Control: Isolated output channels prevent cross-interference, ensuring accurate and 

timely response for critical safety actions (e.g., emergency shutdown triggers).
