Isolated Digital Input
Each of the 16 isolated digital input channels accept voltages from 0 to 30 V. Every
eight input channels share one external common. (Channels 0 ~ 7 use ECOM0.
Channels 8 ~ 15 use ECOM1.) The following figure shows how to connect an exter-
nal input source to the card's isolated inputs.
Figure 3.2 Isolated DI Connection
Isolated Digital Output
If the external voltage source (5~40 V) is connected to each isolated output channel
(IDO) and its isolated digital output turns on (200 mA max./ch), the card's current will
sink from the external voltage source. DB37 provides one EGND pin for IDO connec-
tions.The following figure shows how to connect an external output load to the card's
isolated outputs.
