Product details
Overview & Core Role
- The IS200WROBH1A functions as a WROB relay fuse and power sensing board for General Electric.
- The board attaches to PDIO discrete I/O assemblies and complements TDBS, SRLY, and TDBT host boards.
- The board provides fused power distribution to initial relay outputs and dedicated power to final relay outputs.
Technical Specifications
- Brand: General Electric — Model: IS200WROBH1A — Series: Mark VIe.
- Fuse Value: 3.15 A as the default fused protection rating for relay circuits.
- Redundancy Modes: Supports Simplex, Redundant, and TMR I/O configurations.
- Relay Type: TRLY compatible relay interface for controlled discrete outputs and switching applications.
- Terminal Board Compatibility: Works with TDBTH2, TDBTH4, and TDBTH6 when used in TMR configurations.
- Power Sensing: Detects fused power status across six fused pairings when connected to isolated TDBS voltage.
- Operating Environment: Designed for typical industrial control cabinets and ambient temperature ranges used by Mark VIe.
- Mounting: Plugs directly onto compatible PDIO assemblies and mounts on TDBT for combined terminal functionality.
Key Functions & Benefits
- Provide fused distribution to six initial relay outputs and dedicated power to subsequent relay channels.
- Detect fuse status for reliable diagnostics and reduce downtime through early fuse fault indication.
- Give equivalent terminal-board-plus-contact-input functionality when installed on TDBT in TMR systems.
- Maintain compatibility with Mark VIe architecture for seamless integration and field replacement.
Installation Guide
- Power down the host controller and follow the Mark VIe safety and lockout procedures before installation.
- Align the IS200WROBH1A connector with the PDIO receptacle and seat the board firmly onto the host board.
- Use appropriate torque values for connector screws and verify secure mechanical and electrical contacts.
- Re-energize the system and confirm fuse statuses and relay outputs through the host diagnostic interface.
