149986-01 | Bently Nevada | Spare 16-Channel Relay Control Module

Description

The 16-Channel Relay Module is a full-height module that provides 16 relay outputs. Any number of these modules can be placed in the slots to the right of the Rack Interface Module, offering flexibility in configuration. Each output is independently programmable, allowing it to meet specific voting logic requirements.

Each relay includes “Alarm Drive Logic”, which is programmed using AND and OR logic. This feature enables the use of inputs such as alerts, dangers, Not-OK signals, or individual PPLs (Protected Points Level) from any monitor channel, or a combination of channels. By utilizing the 3500 Rack Configuration Software, users can tailor the module to meet their specific application needs.
