Bently Nevada 149992-01 3500/33-01-00 Spare 16-Channel Relay Output Module
Description：
149992-01 is Bently Nevada 3500 System 3500/33-01-00 16-Channel Relay Output Module, which requires 1 full-height rear slot when installed. 
3500/33 Relay Modules provide a set of relays that can be programmed to actuate based on alarm conditions in other monitor modules in the rack, uses single pole double throw (SPDT) relays.
Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic.
Each relay of the module includes Alarm Drive Logic. Programming for the Alarm Drive Logic uses AND and OR logic and may use the following:
Alarming inputs (alert and danger statuses)
Not-OK
Individual Measured Variables from any monitor channel or any combination of monitor channels in the rack
3500/33 can also be configured to act as if it has DPDT relays. Doing this will use two SPDT relays to perform the function of every DPDT relay that is configured.
Although relay modules are not a required component of the 3500 System, we strongly recommend using them as the most appropriate way to integrate the 3500 System with automatic shutdown applications. Any number of relay modules can be placed in any of the slots to the right of the TDI.
3500 System Configuration software facilitates programing “Alarm Drive Logic” that controls relay actuation. This logic can be based on various combinations of alarms, ranging from an individual channel’s Alert, Danger, or NOT OK status to highly complex Boolean expressions that combine two or more channel statuses to provide special AND or OR voting.By adding the required number of relay modules to the rack, it is possible to provide individual relay contacts for each channel, alarm type, and group of channels for global alarm annunciation.
The 3500 Rack supplies an overall Rack OK relay in addition to any alarm relays in the rack. The Rack OK relay is in the TDI’s I/O module and is connected to the OK circuits of all modules in the rack. These OK circuits monitor the operating condition of each module.
