9472/35 24 V digital input/output modules for Zone 2 Ex n
Sixteen channels can be used in pairs as inputs or outputs (24 V/0.5 A)
The 9472/35 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 switches (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 "Plant STOP" (IEC 61508/up to SIL2).
• Sixteen channels can be used in pairs as inputs or outputs (24 V/0.5 A)
• 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)
