General

• Functional Description - The 9471/35 series digital input/output module for Zone 2 has 16 channels, which can be used in pairs for operation as inputs for contacts, NAMUR proximity sensors (EN 60947-5-6) and PNP proximity switches or as outputs for indicator lamps and low-power solenoid valves. 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.
• Highlights - Sixteen channels can be used in pairs as inputs or outputs Ex nA inputs/outputs with line fault monitoring and LED error and status indication for each channel module in Zone 2 can be hot swapped
