2.3 Usage
By setting the JAn and JBn jumpers, you can choose the isolated or dry
input(see the 2.3.1). And adjust threshold for isolated mode by tuning
VR1(see 2.3.2).
2.3.1 Input Mode Setting
There are 2 jumpers (JAn and JBn, n = 0 ~ 15) associated with each
digital input channel for configuring the channel as isolated or non-
isolated (Dry Contact) input. The digital input channels and their
corresponding jumper is shown below.
Each channel comes equipped with a pair of jumpers for either isolated or
non-isolated selection. If the jumper plugs are installed on the upper
posts of JAn, and JBn (n =0..15), the channel n is configured as
ISOLATED, otherwise the jumper plugs should be installed on the lower
posts to configure as Non-isolated.
