Products description
Technical parameters
Product features

The DB-889D is an expansion multiplexer/ amplifier board for use with A-82X, PCI-1800 series 818 families. Each 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 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
