The Bently Nevada 149992-02 is a Spare 16-Channel Failsafe Relay Output Module designed for emergency shutdown logic and machinery protection within the Bently Nevada 3500 Machinery Protection System. Operating as the dedicated rear I/O component paired with the 3500/33 16-Channel Relay Control Module, the 149992-02 provides 16 single-pole double-throw (SPDT) relay output channels equipped with standard epoxy-sealed electromechanical contacts and 250 Vrms relay arc suppressors. The module receives programmed voting logic commands from the front main module via the 3500 rack backplane, supporting complex AND/OR Alarm Drive Logic based on alert/danger statuses, Not-OK conditions, and individual measured variables from monitoring channels.
