DIGITAL INPUT OUTPUT MODULE SERIES 9470/32

The 9470/32 series digital input/output module for Zone 1 has 16 channels, which can be used in pairs for Exi operation as inputs for contacts and NAMUR proximity sensors (EN 60947-5-6) 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.

• Sixteen channels can be used in pairs as inputs or outputs

• intrinsically safe Ex ia IIC inputs/outputs with line fault monitoring and LED error and status indication for each channel

• module in Zone 1 can be hot swapped
