GE IS200VROCH1BBR Mark VI Series Relay Output Board

The GE IS200VROCH1BBR, also cataloged as the IS200VROC Relay Output Board, operates as a dedicated hardware component for digital output switching and actuator control within GE Mark VI Speedtronic control systems.

Hardware Specifications

Backplane Bus Communication and I/O Density Scaling

The board manages 32 discrete relay output channels across a high-density footprint, transmitting switching signals directly from the controller backplane to field relays. Internal logic processing coordinates with firmware flash compatibility routines to maintain synchronous state updates across all channel latches without inducing backplane signal degradation or bus contention. When deployed in hazardous location configurations alongside compatible IS200TRTDH2D terminal boards, the module ensures electrical segregation between low-voltage logic circuitry and high-voltage field switching contacts.

Frequently Asked Questions

Q: How does channel-level status monitoring operate on the board?

A: Each of the 32 dry contact relay channels features a dedicated surface-mounted LED indicator. The indicator illuminates directly upon receiving a high-state logic command from the backplane, confirming control signal delivery to the terminal interface.

Q: What installation constraints apply when deploying this module in hazardous locations?

A: Hazardous location operation requires interfacing the board exclusively with certified terminal boards such as the IS200TRTDH2D. Technicians must verify that all field wiring maintains physical separation and proper barrier enclosure specs to meet hazardous area classification limits.

Field Installation Guidelines

First, power down the rack assembly before inserting or removing the printed circuit board. Align the module card edges carefully with the rack guide rails, pushing firmly until the backplane connectors seat completely. Subsequently, tighten the top and bottom retaining screws to secure the module against vibration and establish a solid chassis ground connection. When wiring field devices to associated terminal boards (such as the IS200SRTDH1A or IS200TRTDH2D), route low-voltage control lines separately from AC power cables to prevent inductive coupling. Finally, ground all cable shields at a single point on the cabinet earthing bar, ensuring shield continuity across the entire cable run.
