3.3.2 Isolated Digital Outputs

Each of the 16 isolated digital output channels comes equipped with a

darlington transistor. Every eight ouput channels share common

emitters and integral suppression diodes for inductive load, actived by

connecting PCOM to VDD. (Channels 0~7 use PCOM1. Channels

8~15 use PCOM2)

If the external voltage (5~40 V) is connected to each isolated output

channel (IDO) and its isolated digital output turns on (90 mA per

channel maximum), the card's current will sink from the external

voltage.
