Ethernet Trigger Relay Box Quick Start Guide
2
Using the trigger outputs
Each trigger output consists of three connectors, a
corresponding LED on the top, and an internal
relay. When a trigger is activated from Flair
software, the relay for that pair closes, completing
the external circuit and triggering the external
device. The corresponding LED (also numbered 1
to 8) is lit during activation.
The external device that is being triggered must provide its own power for
the trigger circuit, up to 250 Volts AC or 30 volts DC, 10A maximum; for
highly inductive loads current should be limited to 3A. Contact MRMC
for further advice on maximum current for triggering external devices.
In Flair, the button for trigger output 1 is labelled Bloop by default
unless you have changed it, as it is usually used to trigger the Bloop light.
The other buttons in Flair use label numbers that match the trigger
outputs on the Trigger Box; that is, Flair button Trigger 1 corresponds to
output 2, button Trigger 2 corresponds to output 2, etc. Again, you can
change these names in Flair by using the same menu options that you use
to add triggers to a move: Setups >Outputs >#1 - Bloop, #2, #3, etc. See
the Flair documentation for details.
Hint
The LED is powered by the circuit that switches the C (common)
terminal from NC to NO — not by the external circuit that is
completed when the relay closes. Therefore a lit LED only indicates
that Flair has activated the trigger; it is not a check to see if the
external circuit now has current flowing through it.
