1 Introduction
JYTEK'S PCIe-67432 for PCIe bus provides 32CH isolated DI and 32CH iso -
lated DO and robust 2,500V isolation protection, suitable for most
industrial applications.
All digital input channels are identical non-polar and opto-isolated. All
channels are isolated and suitable for collecting digital inputs in noisy
environments. Digital input channel 0 & 1 interrupt are supported.
Common input junction can be common ground or common power,
depending on the environment, such that digital input can be either cur -
rent source or current sink. When isolated digital output is ON, sink cur -
rent is through transistors, and when OFF, none is.
The extra connection is utilized for the flywheel diode, forming a cur
-
rent-release closed loop, whereby transistors are protected from high
reverse voltage generated by the inductance load when output is
switched from ON to OFF.
