Input group IN0...IN3
14568
These inputs are a group of multifunction channels.
These inputs can be used as follows (each input separately configurable):
• analogue input 0...20 mA
• analogue input 0...10 V
• analogue input 0...32 V
• voltage measurement ratiometric 0...1000 ‰
• binary input plus switching (BL) for positive sensor signal (with/without diagnosis)
• binary input minus switching (BH) for negative sensor signal
• fast input for e.g. incremental encoders and frequency or interval measurement
→ chapter
Possible operating modes inputs/outputs
(
Sensors with diagnostic capabilities to NAMUR can be evaluated.
All inputs show the same behaviour concerning function and diagnosis.

If the analogue inputs are configured for current measurement, the device switches to the safe
voltage measurement range (0...32 V DC) and the output RESULT is set accordingly in the
function block INPUT when the final value (23 mA for > 40 ms) is exceeded. After about one
second the input automatically switches back to the current measuring range.

These inputs are a group of multifunction channels.
These inputs can be used as follows (each input separately configurable):
• binary input plus switching (BL) for positive sensor signal
• input for resistance measurement (e.g. temperature sensors or fuel sensors)
