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.
