I/O Density and Mark VI Hardware Integration
The IS200VROCH1BBR concentrates multiple digital switching functions on a single board, providing 32 output channels for connection to external control circuits. Channel status LEDs support direct local observation during commissioning and troubleshooting.
Within the GE Mark VI hardware architecture, the board operates as part of the distributed control I/O arrangement. Correct system operation depends on compatibility with the designated Mark VI cabinet hardware, associated terminal connections, and applicable controller configuration. Before replacement or commissioning, verify the complete board identification and installed hardware revision.
Frequently Asked Questions
Q: Does the IS200VROCH1BBR provide analog output signals?
A: No. The provided information identifies the IS200VROCH1BBR as a Digital Output PAB Board using dry contact relay outputs for switching external circuits.
Q: How many digital output channels are provided?
A: The board provides 32 digital output channels according to the supplied technical data.
Q: Can the LED indicators be used for field diagnostics?
A: Yes. The integrated LED indicators provide local status indication for output channels. Field wiring and external device operation should still be verified with appropriate electrical test procedures.
Field Installation Guidelines
Install the GE IS200VROCH1BBR only in the designated Mark VI hardware location and verify the full part number before mounting.
Disconnect or isolate system power according to the applicable site lockout and electrical safety procedure before removing or installing the board.
Inspect the board connectors, mounting points, and associated terminal hardware for damage or contamination before installation. Do not force connectors into position.
Route field wiring separately from high-energy power conductors where practical. Follow the cabinet grounding and shielding arrangement specified for the Mark VI installation.
After installation, verify connector engagement and field circuit continuity. Then confirm channel status through the board LEDs and system diagnostics before placing connected equipment into operation.
