The 9470/32 series digital input/output module for Zone 1 and Class I, Div. 1 has 16 channels, which can be used in pairs for I.S. 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 isolated from the system.
- 16 channels can be used in pairs as inputs or outputs
- Intrinsically safe Ex ia inputs/outputs with line fault monitoring and LED error and status indication for each channel
- Module hot swap in Zone 1 and Class I, Div. 1
