Product Overview

The GE IS230SNRLH2A is a discrete output relay module designed to switch external loads from a GE control system using relay-isolated outputs. It is commonly deployed where field devices such as interposing relays, solenoids, alarms, and contactor coils must be driven with electrical isolation and clear ON/OFF state control. The module is built for industrial control cabinets and is typically mounted in DIN-rail assemblies as part of GE excitation and turbine control hardware families.

This relay output module supports maintainable wiring practices and improves fault finding by separating control electronics from field power circuits. It is used as a spare or replacement module in installed systems where reliable discrete actuation is required.

Hardware Parameters

• Recommended practices

• Use appropriately rated fusing and suppression for inductive loads (coils/solenoids)

• Follow cabinet grounding and segregation rules to reduce noise coupling

• Verify relay contact ratings against the actual load and inrush current (application-specific)

Industrial Applications

• EX2100 excitation control cabinets requiring relay-isolated discrete actuation

• Power generation auxiliary control including alarms, permissives, and interlocks

• Turbine and generator balance-of-plant automation where discrete outputs must interface to higher-energy field circuits

• Retrofit and spare replacement for DIN-rail output modules in legacy GE control installations
