9469/35 HART universal modules Zone 2 Ex n
Eight channels can be used as analogue inputs or outputs, and four of these channels can used as binary inputs or outputs
The 9469/35 HART analogue universal module for Zone 2 has eight channels which can be used separately for operation of 2-/3-/4-conductor HART transmitters, or control valves/positioners, as well as for operation of 3-conductor proximity switches and 24 V/0.5 A binary outputs.
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 as analogue inputs or outputs, and four of these channels can used as binary inputs or outputs
• Ex ec inputs/outputs with line fault monitoring, an LED fault and status display for each channel and SIL2 shutdown input
• Module in Zone 2 can be replaced without having to disconnect the power supply (i.e. hot-swapped)
