2.12 The Relay Module Interface
The Relay Module Interface can be controlled directly either from HQi or can be manipulated through the Action Plan
interface in order to trigger external devices. Each Relay Module Interface corresponds to one port on the two-port
Relay module. Each port typically has 4 available relays. When relay 1 is open, pins 1 and 2 are bridged.
See Chapter 6: Creating and Using Action Plans for more information on interfacing with the Relay Module interface.

Module interface.
