IS230SDIIH1A Simplex Contact Input Module
Brand: General Electric (GE Energy) · Series: Mark VIe · Type: Contact Input with Point Isolation Terminal Board
Product Overview
IS230SDIIH1A is a 16-channel simplex contact input module from the Mark VIe series. It provides isolated voltage detection for relay contacts, switches, fuses, and other field devices. The module combines an IS200SDII terminal board with a PDII I/O pack. It supports point-isolated or group-isolated configurations via optional WDIIH1 / H2 / H3 boards.
Designed for GE Distributed Control Systems, this module delivers reliable DC/AC sensing across multiple voltage levels. It suits turbine control, power generation, and heavy industrial automation.

Frequently Asked Questions
- Q: Can I mix point-isolated and group-isolated channels?
Yes. With WDIIH1 or WDIIH2, each channel can be individually configured. - Q: What is the maximum wire resistance per input?
15 Ohms maximum lead resistance for reliable voltage sensing. - Q: Does the module support 48 V dc wetting?
Yes, via WDIIH2 option board (group isolation). - Q: Is the IS230SDIIH1A compatible with older Mark VI systems?
Primarily designed for Mark VIe, but electrical compatibility exists with adapters.
