Product Description

The IS230SNCIH2A is a discrete contact input I/O pack for the GE Mark VIe and GE Mark VIeS distributed control platforms. It digitizes dry contact field signals and transmits data through the dual-redundant IONet Ethernet network, enabling high-speed communication for turbine and generator control applications.

The H2A revision improves signal processing speed and noise immunity, making it suitable for precision control and safety monitoring. The module supports simplex, dual, and TMR (Triple Modular Redundant) architectures to meet different reliability requirements. Integrated diagnostics and sequence-of-events (SOE) recording support fast fault analysis in critical systems.

Frequently Asked Questions

Q1: Difference between IS230SNCIH2A and IS200 series?
The IS230 version is an intelligent I/O pack with built-in processing and Ethernet communication, while IS200 modules are typically legacy base-board components with slower bus architectures.

Q2: Does it require a separate power supply?
No. The module receives 28 V DC logic power through the terminal board connected to the system power distribution module.
