149986-02 | Bently Nevada 3500/32M Spare 4-Channel Relay Control Module

Description:

The Bently Nevada 149986-02 3500/32M 4-Channel Relay Module is a full-height module providing four relay outputs. It can be placed in any slot to the right of the Transient Data Interface Module. Each relay output can be independently programmed to perform voting logic and includes Alarm Drive Logic. The Alarm Drive Logic uses AND and OR logic, with inputs including Alert and Danger statuses, Not-OK, or individual PPLs from any monitor channel or combination of channels in the rack. Programming is done using the 3500 Rack Configuration Software.
