Relay Control
-
- 16 Independent Channels: Each relay can be configured to control external devices (e.g., pumps, valves, alarms) based on input signals from the 3500 system.
- Voting Logic: Supports AND/OR logic programming to trigger outputs based on combinations of alarm states (e.g., requiring two out of three sensors to trip before activating a relay) 216.
- Alarm Drive Logic: Integrates with monitor channels’ alert/danger statuses for automated fault responses.
