PART 3 - MEASURING CHANNEL CONNECTIONS
Internal wiring for each Measuring Channel in a rack or instrument enclosure is in
modular format. Each Measuring Channel requires:
 A Back Plane PCB to connect to the Measuring Channel
 A Back Panel PCB for sensor input and analog voltage or current output
 A 6 inch interconnecting ribbon cable between back plane and back panel for
output
 Interconnecting 6 inch coaxial cable(s) for sensor input. One cable is required for
a single coil sensor. Two cables are required for a dual coil sensor.
3.1 Back Plane PCB
The Back Plane PCB is installed to the horizontal rails inside the rack and secured with
four screws. A Back Plane PCB is required for each Measuring Channel installed in the
rack. Its purpose is to provide all I/O connections to each Measuring Channel, which
are:
 Sensor
connections
 Input
power
 Synchronization
signal
 Analog
output
 Optional Display Module input signals
