Allen-Bradley 1719-CF4H is an Ex I/O 4-channel HART analog configurable module that ships with the 1719-TB8 eight-pole terminal block for field wiring. Each channel can be configured as either an analog input or an analog output, enabling use with HART-enabled transmitters on AI channels and driving actuators on AO channels. This four-channel module is part of Rockwell's Ex I/O family designed for hazardous-location installations. The Ex I/O 4CH HART Analog Configurable designation reflects its capability to handle four discrete HART channels with per-channel AI/AO configuration.
