DB-889D Wiring Diagram
|The DB-889D have two 37-pin D-sub connector and two 20-pin header. the one D-sub connector connected to A/D Board's analog input connector and another one can be cascaded to another sceondery DB-889D.The 20-pin header is DB-889D' control logic circute. It is connected to A/D board's digital output port from 20-pin flat cable. then the digital output can control multi-plexer and amplifer.|
The DB-889D provides 16-channel analog input and CJC circuit for thermocouple input.
