Bently Nevada 125720-02 3500/32M Spare 4-Channel Relay Output Module
Bently Nevada 125720-02 3500/32M Spare 4-Channel Relay Output Module
Technical Specifications:
Description
The Bently Nevada 125720-02 4-Channel Relay Module is a full-height module that provides four relay outputs. Any number of 4-Channel Relay Modules can be placed in any of the slots to the right of the Transient Data Interface Module. Each output of the 4-Channel Relay Module can be independently programmed to perform voting logic.
Each relay utilized on the 4-Channel Relay Module includes Alarm Drive Logic. Programming for the Alarm Drive Logic uses AND and OR logic, and can use alarming inputs (Alert and Danger statuses), Not-OK, or individual PPLs from any monitor channel or any combination of monitor channels in the rack. You can program this Alarm Drive to meet your application needs using the 3500 Rack Configuration Software.
