The 9468/33 Series HART Analog Universal Module for Zone 2, Cl. I, II, Div. 2 has eight channels that can be used individually for Ex i operating two-/three-conductor HART transmitters, four-conductor transmitters, or control valves/positioners with 0/4 to 20 mA signals. HART communication is bidirectional. All inputs/outputs are short-circuit proof, galvanically separated from the system, and individually monitored to check for line faults.
