Concept 3000 Relay Expander
The 8 Relay Expanders provide low voltage, high current relay outputs, offering a general
purpose interface in applications such as warning devices (strobes, etc.), air-conditioning,
process control and access control including door locks, lift call and lift floor selection.
One Relay Expander board can be connected to the Control Module via the Bus Latch PCB
to provide 8 Relay outputs. If extra relays are required, they can be installed in Zone
Expander Modules using the 8 Relay Expander Kit P/N: 993082E.
An external power supply option can be used whenever the Relay board power requirements
exceed the current available from the Control Module.
