105043-01 | SP-110997/SP-105044 PC Board

The Discrete card contains four programmable 11-bit digital to analogoutputs. These outputs allow a±1024 times 2 or ±2048 drive signal to beconverted to a± 10V DC analog output, thus giving 9.76 millivolts per bitresolution. Through programming of associated Scale and Offset
parameters the effective range of the Drive signal can be extended to±32767.The digital Drive signal can be any of the 1395 run-timeparamcters. External connections are made to Terminal Block TB-3.
There are two board configuration options available for the DiscreteAdapter Board LO,120V AC or 24V DC.The 120V AC Adapter Boardconfiguration has a bank of four two watt resistors located directly aboveJ3. These resistors drop the 120V AC down, and it is then sent through arectifier and opto-isolator. The 24V DC version also has a bank of smallerresistors. As this is the only difference between the boards, it provides aneasy method of identification.
