Technical Specifications

The 149986-01 is a high-density 16-channel relay control module designed for the Bently Nevada 3500 Series Machinery Protection System. This full-height module provides sixteen independent relay outputs that can be programmed to actuate based on alarm conditions sensed by other monitors in the rack. Featuring sophisticated voting logic and “Not OK” relay status monitoring, the 3500/33 ensures highly reliable machinery shutdown and annunciation capabilities, making it an essential component for complex industrial safety and asset protection architectures.

Product Q&A

Q: Can the 3500/33 relay module be configured for “AND” or “OR” voting logic? A: Yes, the module is fully programmable through the 3500 Rack Configuration Software, allowing users to define complex voting logic across multiple channels and monitor inputs to meet specific machine protection requirements.

Q: Does the 149986-01 support redundant power inputs from the 3500 rack? A: Yes, like all 3500 series modules, the 16-channel relay module draws power from the redundant backplane, ensuring that the relay states remain manageable even if one power supply module fails.
