3.1.3 APAX-5046 24-ch Digital Output Module
The APAX-5046 features 24 digital output (sink) channels. The digital output chan-
nels offer short-circuit protection and LED to indicate digital status. The module pro-
vides 2500 VDC optical isolation between channels and backplane bus. If any high
voltage or current damage the channels, the whole system (backplanes, other mod-
ules, and control unit) won't be affected because it is already isolated.

Warning! Please use different power supply modules for digital channels and sys-
tem to ensure isolation effect.
Warning! When you connect DO channel with inductive load, we suggest adding
one diode in the circuit to protect the APAX-5046 module. (Refer to fig-
ure below)
