 Interface Card (IQ/Skil/EH/Q)
The CVA and ROMPAK do not require in additional interface card.
The interface card is profiled and assembled to fit an IQ, Skil or Q actuator. For the Skil/EH and
Q, it carries the processor for collecting the data from the actuator main board and passing this
data to the Network Interface card. For the IQ/IQT it is used simply for physical connection to
the main card.
The primary connection to the actuator circuits is by a multi-pin connector on the Interface Card
that, due to its physical shape may only be fitted in the correct polarisation. Internal wiring
harnesses connect to the Interface card for other signals and options within the actuator. The
Interface card is powered from within the actuator.
