3500/33

3500/33 16-Channel Relay Module

The 3500/33 16-Channel Relay Module is a high-performance, full-height module designed to provide 16 relay outputs. It can be easily integrated into the system by placing it in any of the slots to the right of the Transient Data Interface (TDI) Module.

Technical Specifications

• Independent Output Programming: Each output can be programmed to perform voting logic, enabling flexible and customizable configurations.
• Alarm Drive Logic: Includes logic for alarming inputs, Not-OK status, and measured variables from monitor channels.
• Customizable Logic: Programming can be done using the 3500 Rack Configuration Software. Logic can be based on AND/OR conditions.
