Most important technical data

8.1

Power supply

Supply voltage
• DC voltage version
12...30 V DC
Current consumption
• Without load < 60 mA, with reverse polarity protection
Power supply failure
• Behaviour in case of overvoltage
The device works continuously without any damage up to 34 V DC.
If the supply voltage is exceeded, the properties specified are no longer guaranteed.
• Behaviour in case of undervoltage
If the supply voltage drops below the minimum value, the device switches off (status as if not
supplied with power = switch open)

Output

Switching capacity
• Switch status ON: I
• Switch status OFF: I
• Switching cycles: > 10,000,000
• Voltage drop PNP: ≤ 2 V
• Overload resistance
Automatic load check of switching current; output is switched off in case of overcurrent, the
switching current is tested again every 0.4 s;
max. capacitance load: 14 mF at max. supply voltage (without resistive load)
max. period length: 0.5 s; min. t
Load (analog output)
• Max. (V
supply
Signal on alarm
• Analog output
≤ 3,6 mA / last current value / ≥ 21,0 mA adjustable
(if setting Š 21.0 mA the output is ≥ 21.5 mA)
