The E2-MIX20884-Dmodule offers dual Ethernet ports that allow it to be used in fault-tolerant ring topologies, and provides the following inputs and outputs:
Discrete: up to 20 inputs, including four isolated high-speed counters, and eight outputs
Analog: eight 4-20mA inputsandfour 0-20mA, 4-20mA, 0-5V outputs.
This high-density of mixed I/O allows customers to reduce costs versus traditional single-function I/O.
