DB-889D
16-channel Analog Multiplexer Board
● Connects directly to A-82X, PCI-1800 series DAS board or 818 families with D-sub 37-pin connectors.
● Cold-junction compensation for thermocouples, thermocouple open detection Input filtering
● Software-programmable Instrumentation amplifier gain of 0.5, 1, 5, 10, 50, 100, 500, 1000
● Daisy chain to 10 pcs
The DB-889D is an expansion multiplexer/ amplifier board for use with A-82X, PCI-1800 series 818 families. Each DB-889D multiplexes 16 differential analog input channels into one analog input of the DAS board. The high grade instrumentation provides software programmable gains of 0.5, 1, 5, 10, 50, 100, 500, and 1000.
Thermocouple measurement are handled easily with DB-889D. The board includes cold-junction sensing and compensation circuitry that provides a scaling of 24.4 mV/°C. Biasing resistors are includes for open thermocouple detection. The 889D can be cascaded to a total of 128 channels of voltage measurements or 112 channel of thermocouple measurement.
APPLICATIONS:
● Signal Conditioning
● Energy Management
● Analog Multiplexer
