GE IS220PDIOH1A Key features
High channel density—supports 32 inputs and 16 outputs in compact form factor
Opto-isolated channels protect against electrical noise and ensure signal integrity
Response time under 1 ms enables fast system reactions
Relay outputs support external alarms, interlocks, or control actions
Rugged design with conformal coating and industrial temperature range
Performance comparison
Parameter | PDIOH1A (standard) | PDIOH1B (no coating) | PDIOX (discrete-only) |
Digital Inputs | 32 | 32 | 32 |
Relay Outputs | 16 | 16 | 0 |
Isolation | Opto | Opto | Opto |
PCB Coating | Conformal-coated | None | None |
Summary:
Compared to PDIOH1B (no coating) and PDIOX (digital only), PDIOH1A offers full 32/16 I/O with opto-isolation and conformal coating. Signal-only versions omit relays and protective coating.
Typical cooperation cases
UAE Smart Grid Integration
In Abu Dhabi's renewable energy plants, the module managed 16-channel I/O for solar inverters, ensuring <5ms response time under 50°C ambient temperatures.
Qatar Petrochemical Safety Systems
Deployed in Ras Laffan ethylene plants, it achieved SIL3 compliance for emergency shutdowns, withstanding 6g vibration and 98% humidity.
Oman Water Desalination Control
Integrated into Salalah PLCs, the module's -30°C to +75°C operating range ensured 24/7 operation amid coastal salt fog corrosion.
Oil Refinery Automation in Saudi Arabia
GE IS220PDIOH1A module was integrated into a Saudi Aramco refinery's DCS system, achieving 99.95% uptime for critical process control, reducing unplanned downtime by 35% annually through 64-channel I/O redundancy.
