3.3.2

Isolated Output

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

Every eight output channels share common emitters and integral suppression diodes

for inductive load, activated by connecting PCOM to VDD. (Channels 0~7 use

PCOM1. Channels 8~15 use PCOM2.)

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

and its isolated digital output turns on (200mA per channel maximum), the card's cur-

rent will sink from the external voltage.
