APAX-5040 24-ch Digital Input Module

The APAX-5040 features 24 digital input (sink/source) channels. The APAX-5040
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 digital
input channels offer 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 system (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.
