The PCLD-789D is a front-end signal conditioning and channel
multiplexing daughterboard for use with PC-LabCard analog input ports.
It multiplexes 16 differential input channels into a single A/D
converter input channel. You can cascade up to ten PCLD-789Ds, allowing
a single data acquisition card to access 160 analog input channels. The
PCLD-789D has DB-37 and 20-pin flat cable connectors and lets your
PCL-818L or PCL-818HD access up to 128 channels without using an
additional digital output cable to select channels. The PCLD-789D uses
a high-grade instrumentation amplifier that provides switch-selectable
gains of 1, 2, 10, 50, 100, 200 and 1000. This amplifier lets you
accurately measure low-level signals with your PC-LabCard. The board
also contains a cold-junction sensing circuit that allows direct
temperature measurement from thermocouple transducers. A wide variety
of thermocouples are supported with software compensation and
linearization.
