10 Novara ControlPads & KeyPads
Relay 1 / Relay 2 Connectors
The "Relay 1" and "Relay 2" Output ports each act as a switch to GND and are rated at 100 mA @ 12 VDC.
These Output ports are used to control external devices (i.e. the PC1 Power Controller or AMX UPC-20+
Universal Power/Motor Controller - not included).
These Output ports do not function like "Relay" ports on other AMX equipment:
The Relay 1 and Relay 2 output ports are current sinks, not voltage drivers, they switch the ports to
GND.
The "SHARED +12V" connector is common +12 VDC (not Ground).
These Output ports use 5V logic, but can handle up to 12V on the input without harm - at higher
voltages you run a higher risk of surge damage.
FIG. 8 illustrates connecting the RELAY 1 (Output) Connectors to a PC1 Power Controller, in momentary/
latching mode.
The Relay ports are for external relay control only.
