The 9468/33 series HART Analog Universal Module for Zone 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.
- Eight channels can be used individually as inputs or outputs
- intrinsically safe Ex ia IIC inputs/outputs with line fault monitoring
- module in Zone 2 can be hot swapped
