6.5 Relay Module (3-8900.403-X)
6.6 8059 External Relay Module
• 8059 external relay modules provide 4 additional
dry-contact relays.
• External modules are controlled via the
digital (S
3 L) serial bus.
The alarm is OFF during normal
operation, and will go ON
according to 8900 Relay settings.
The valve is ON during normal
operation, and will go OFF
according to 8900 Relay settings.
