3636R Invensys - Relay Output Module | 32-Point

Invensys 3636R Relay Output Module Overview

The Invensys 3636R Relay Output Module handles non-critical control points that need relay outputs. This non-triplicated module is ideal for interfacing with annunciator panels and other devices not suited for high-side solid-state switches. It receives output signals from three main processor channels, votes on the data, and uses the result to control its 32 individual relays.

Key Features and Diagnostics

• The module runs continuous diagnostics to monitor its operational health.
• Each output has a loopback circuit that checks relay operation without needing an external load.
• A clear Fault indicator activates immediately if any diagnostic failure occurs.
• This fault condition also triggers the chassis alarm to alert system operators.
• Support for hot-spare modules helps maintain system uptime and reliability.
• Installation requires a separate External Termination Panel (ETP) that connects to the Tricon backplane.
