Overview

The 4-Channel Relay Module is a full-height module designed to provide four independent relay outputs. These modules can be installed in any slot to the right of the Transient Data Interface Module, with no restrictions on the number of modules used. Each output channel can be programmed individually to execute custom voting logic.

Each relay within the 4-Channel Relay Module features integrated Alarm Drive Logic, which can be configured using AND/OR logic. The logic can utilize alarm inputs, including Alert and Danger statuses, Not-OK signals, or individual PPLs from any monitor channel, as well as combinations of channels within the rack. The module's Alarm Drive Logic is fully customizable to suit specific application requirements, and all configurations are done through the 3500 Rack Configuration Software.
