GE IS220PDIOH1B Discrete Input/Output Module
The IS220PDIOH1B is a discrete input/output pack manufactured by General Electric for the Mark VIe Speedtronic turbine control platform. It integrates digital input acquisition, relay output control, local processing, and dual Ethernet communication into a compact module. Designed to interface field contact signals with turbine controllers, the unit supports 24 contact inputs and 12 Form C mechanical relay outputs.
Functional Overview and Architecture
The module processes discrete field signals and executes control commands within turbine management applications. It features optical group isolation up to 1500 V for signal protection and includes a hardware input filter rated at 4 ms. Nominal operating voltage is established at 28.0 V DC, supporting contact input voltage rejection up to 60 V RMS at 50/60 Hz with a 125 V DC wetting voltage.
Monitoring and Diagnostics
System reliability is maintained through dedicated relay and coil monitoring across all 12 outputs, alongside 3 multiplexed feedback channels capable of tracking up to 6 fuses. Built-in diagnostics execute power-up self-tests, power supply tracking, and input feedback verification. The unit also supports Sequence of Events recording at a scan rate of 1,000 Hz.
