DAEnetIP4
IP controller (the core of the current module) supports 8 digital inputs
every of which is combined with 16 bit cyclic counter. These inputs are extended with
Schmitt triggers in this module so they are able to handle voltages from 0 up-to 30V
DC. Moreover every digital input can control digital output (relay) and send traps up-
on falling and/or rising edge of the input signal. For more information please refer to
