3.1.2 APAX-5045 24-ch Digital Input/Output Module
The APAX-5045 features 12 digital input (sink/source) and 12 digital output (sink)
channels. The APAX-5045 module's digital input channels can accept a 2-wiring
input from a DC voltage source, to determine the state of limits, standard switches or
proximity switches. The APAX-5045 module's digital output channels can generate
discrete signal to external devices and change its output value to control the
devices. The digital output channels offer short-circuit protection and LED to indicate
digital status. The module provides 2500 VDC optical isolation between channels and
backplane bus. If any high voltage or current damage the channels, the whole sys-
tem (backplanes, other modules, 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.
