The HART 9469/35 universal module for Zone 2 has 8 channels that are suitable for separately operating 2-/3-/4-line HART transmitters, control valves/position regulators and operating 3-line proximity switches and binary 24 V / 0.5 A outputs.
Signals can be used. HART communication is bidirectional. All inputs/outputs are short-circuit proof, galvanically separated from the system and individually monitored to check for line faults.
- 8 channels can be used as analogue inputs or outputs, and 4 of these channels can used as binary inputs or outputs
- Ex nA 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 during operation (hot swap)
