This Interface Unit (IFU) is from the Electronic Pack (EP) of the NCS1. The IFU is located at the lower part of the EP between the two Inverters on the left and the Digital Computer Unit (DCU) on its right.
The IFU converts system analogue signals to digital form and buffers them to the Digital Computer Unit [DCU]. It also buffers the DCU digital outputs before converting them into analaogue signals for use in control circuits; it also produces timing, sequencing and alarm signals.
The Identification Label shows the company as Marconi-Elliott Avionics and the Serial No. prefix as 90 (1990). The NCS1 system was probably not made much after 1984 which would put the Interface Unit manufacturer as Marconi Avionics. The systems have been maintained in service and it is possible that some were refurbished as new but further investigation is needed.
