3500/32 4-Channel Relay Module

This module provides four (4) relays that can be configured to actuate based on user-configurable alarms and voting logic within the 3500 rack. Multiple relay modules can be installed in the 3500 rack as needed to meet annunciation and machine protection requirements.

3500/33 16-Channel Relay Module

With sixteen (16) relays, this module offers four times the density and greater configuration flexibility than the 3500/32 module. The 3500/33 is recommended as the most cost-effective solution when more than 12 relays are required in a single 3500 rack, rack space is at a premium, and/or when the user's relay voting logic requirements cannot be met by the 3500/32.

3500/34 TMR Relay Module

A special relay module used in triple modular redundant (TMR) applications of the 3500 System.
