BENTLY NEVADA 3500/32M 149986-02 Spare 4-Channel Relay Control Module

Description:

The BENTLY NEVADA 3500/32M 149986-02 4-Channel Relay Module is a full-height module that provides four relay outputs. These modules can be placed in any available slots to the right of the Transient Data Interface Module. Each relay output on the 4-Channel Relay Module can be independently programmed to perform voting logic. Additionally, each relay includes Alarm Drive Logic.

Programming for the Alarm Drive Logic utilizes AND and OR logic and can incorporate alarming inputs such as Alert and Danger statuses, Not-OK signals, or individual PPLs from any monitor channel or any combination of monitor channels in the rack. You can customize this Alarm Drive to suit your specific application needs using the 3500 Rack Configuration Software.
