General Electric IS230SNRLH2A Mark VIe Discrete Output Module

Description

The IS230SNRLH2A operates as a discrete output module within the Mark VIe control platform series. This assembly is built from an IS200SRLY terminal board coupled with a PDOA I/O pack to deliver remote switching capability. The component provides 12 form C relay output circuits deployed across 48 pluggable-type physical terminals. To customize functional capabilities, the module can interface with auxiliary option boards including the IS200WROB, IS200WROF, and IS200WROG boards via integrated mating connectors. For example, integrating the IS200WROF alternative introduces an individual serial fuse protective link onto every single relay common trace alongside discrete fuse voltage feedback loops, accommodating either AC or DC external wetting voltages across the switching circuitry.

Features

• Provides 12 form C relay output contact loops routed across a 48-terminal wiring field.
• Combines an internal IS200SRLY board assembly and a PDOA processing pack into one component.
• Includes dedicated board connectors to interface with IS200WROB, IS200WROF, or IS200WROG option expansion units.
• Supports broad flexibility by routing either AC or DC incoming wetting voltage vectors through selective option board attachments.

Applications

• Mark VIe Gas and Steam Turbine Controls: Directing industrial field relay excitation and automated valve execution paths.
• Simplex Redundant Digital Output Blocks: Providing clean contact sequencing hooks for general power distribution loops.
• Isolated Interlocking Circuits: Interfacing process control instrumentation logs to auxiliary remote machinery cabinets.

Installation Guidelines

• Disconnect all control power feeds prior to snapping the base mounting housing onto the tracking carrier.
• Align the module firmly onto the standard DIN rail track until the locking tabs latch completely into place.
• Use pluggable terminal blocks to land field wires before inserting them into the terminal board frame.
• Ensure option boards are properly aligned with the on-board connectors to establish solid electrical paths for the wetting lines.
