The 9472/35 series 24 V digital input/output module for Zone 2 has 16 channels, which can be used in pairs for operation as inputs for contacts and PNP or NAMUR proximity sensors (EN 60947-5-6) or as outputs for solenoid valves up to 24 V/0.5 A. Eight inputs can be used for frequencies of up to 20 kHz, and four can be used for detecting the direction of rotation.
All inputs/outputs are short-circuit proof and galvanically separated from the system. Additional control input for "System OFF" (IEC61508 / through SIL2)
- Sixteen channels can be used in pairs as inputs or outputs (24V/0.5 A)
- Ex nA inputs/outputs with line fault monitoring and LED error and status indication for each channel plus SIL 2 shutdown input
- Module in Zone 2 can be hot swapped
