The IS230SNRLH2A is a discrete output I/O pack for the GE Mark VIe and GE Mark VIeS control platforms. It interfaces the system logic solver with field devices such as solenoid valves, relays, and motor starters, providing fast and reliable switching.
This A-rated revision supports simplex configurations and is compatible with PDOA-impacted environments. As part of the Mark VIe distributed architecture, it includes onboard diagnostics to monitor output circuit health and communication integrity over IONet. The modular IS230 standard assembly and DIN-rail mounting simplify installation and maintenance.
