7. 1 Display Version
7.1.1 Power Supply
Supply voltage
• DC voltage version
12...30V DC
Current consumption
• Without load < 60 mA, with reverse polarity protection
Power supply failure
• Behavior in case of over voltage
The device works continuously without any damage up to 34V DC.
If the supply voltage is exceeded, the properties specified are no longer guaranteed.
• Behavior in case of under voltage
If the supply voltage drops below the minimum value, the device switches off (status as if
not supplied with power = switch open).
7.1.2 Output
Switching capacity
•Switch status ON: I
a
≤ 250 mA
•Switch status OFF: I
a
≤ 1 mA
• Switching cycles: > 10 000 000
• Voltage drop PNP: ≤ 2V
• Overload protection
Automatic load check of switching current; output is switched off in case of over current,
the switching current is tested again every 0.4 sec.; max. capacitance load: 14 μF at max.
supply voltage (without resistive load) max. period length: 0.5 sec.; min. t

≥ 10 mA
Signal on alarm
•Analog output
≤ 3.6 mA / last current value / ≥ 21.0 mA adjustable
(if setting ≥ 21.0 mA the output is ≥ 21.5 mA)
