3.3 Expanding Analog Inputs
You can expand any or all of PCM-3718’s A/D input channels by using
multiplexing daughterboards. Most daughterboards are connected
directly to the module’s 20-pin connectors. You may require the PCLD-
8115 Screw-terminal Board for connections.
The PCLD-789 Amplifier and Multiplexer multiplexes 16 differential
inputs to one A/D input channel. You can cascade up to eight PCLD-789s
to the PCM-3718H/3718HG for a total of 128 channels.
The PCLD-8115 Screw-terminal Board makes wiring connections easy.
It provides 20-pin flat cable connectors and a CJC (Cold Junction Com-
pensation) circuit which lets you directly measure thermocouples. You
can handle all types of thermocouples with software compensation and
linearization.
Special circuit pads on the PCLD-8115 accommodate passive signal con-
tioning components. You can easily implement a low-pass filter, attenua-
tor or current shunt by adding resistors and capacitors.
