Expanded ConnectivityEight-point input (IE8H) and output (OE8H) HART analog modules allow for communication with smart field devices that support the HART protocol. Modules can access the HART digital signal in parallel to the module&rsquos 4-20 mA analog signal with no effect on the processing of the analog. Modules allow users to connect to ControlNet or EtherNet/IP networks, HART field devices, HART handheld programming terminals, controllers, and HMI products.
