Functional Description
The IS200WROBH1AAA board is designed to provide discrete contact outputs with fuse protection and monitoring. It can be used with TDBS boards, where six jumpers allow power application or removal from relays. Additionally, when paired with SRLY boards, the WROB board uses isolated voltage feedback to detect fuse status across six fuse pairs.
Features
Fuse Monitoring: Isolated voltage feedback for fuse status detection.
Relay Control: Six jumpers for relay power management with TDBS boards.
Redundancy Support: Operates in simplex, redundant, or TMR configurations.
Durable Design: Conformal coating for environmental protection.
Frequently Asked Questions (FAQ)
Q: What are the default fuse values of the IS200WROBH1AAA? A: The default fuse values are 3.15 A.
Q: How many jumpers are on the board, and what is their function? A: The board has six jumpers that can apply or remove power from relays when used with a TDBS board.
Q: Can the IS200WROBH1AAA be used with SRLY boards? A: Yes, it can be used with SRLY boards, where isolated voltage feedback detects fuse status.
Field Installation Guidelines
Mount the IS200WROBH1AAA securely within the Mark VIe chassis.
