Bently Nevada Relay Output Isolation and Fail-Safe Switching Architecture
The 3500/32-01-01-00 implements galvanically isolated relay switching paths between each output channel and the rack backplane logic domain. Each channel operates as an independent electromechanical Form C contact set, supporting separation of alert and danger logic paths.
Cross-channel isolation design suppresses fault propagation during relay state transitions. The relay drive stage is synchronized with 3500 system alarm tables, ensuring deterministic state execution under configured trip conditions. Hot-swap insertion logic maintains backplane integrity while isolating contact transitions to prevent unintended actuation during module exchange.
Frequently Asked Questions (FAQ)
Q: Can the relay channels operate independently within the same module?
A: Yes, all four Form C relay outputs are independently configurable and driven by separate alarm logic assignments.
Q: Does hot-swap operation affect relay state continuity?
A: During insertion or removal, relay outputs transition to a defined safe state to prevent unintended circuit activation.
Q: What is the electrical isolation boundary of the module?
A: Each relay channel provides 500 Vrms isolation to adjacent channels and rack ground reference.
Field Installation Guidelines
-
Insert module only into compatible 3500 rack slots with backplane alignment verified.
-
De-energize field relay wiring before module replacement to avoid unintended actuation.
-
Maintain separation between relay output wiring and low-level signal cabling.
-
Ensure proper grounding of rack chassis to maintain isolation performance.
-
Verify OK and relay status LEDs after commissioning before enabling external trip circuits.
