6.1.2 Supply voltage
Supply voltage IO-Link: 10 to 30 V DC at a DC power unit
IO-Link communication is guaranteed only if the supply voltage is at least 18 V.
6.1.3 Current consumption and alarm signal
Intrinsic power consumption Alarm current (for devices with analog output)
1)
≤ 60 mA ≥21 mA (factory setting)
Maximum current consumption: ≤ 300 mA
1) Setting min. alarm current ≤3.6mA can be ordered via the product order structure. Min. alarm current
≤3.6mA can be configured at the device or via IO-Link.
6.2 Switching capacity
• Switch state ON

• Switch cycles: >10,000,000
• Voltage drop PNP: ≤2 V
• Overload protection: Automatic load testing of switching current;
– Max. capacitive load: 1 μF at max. supply voltage (without resistive load)
– Max. cycle duration: 0.5 s; min. t

6.3 Connection data
6.3.1 Load (for devices with analog output)
In order to guarantee sufficient terminal voltage, a maximum load resistance R
L
(including
line resistance) must not be exceeded depending on the supply voltage U
B
of the supply
unit.
The maximum load resistance depends on the terminal voltage and is calculated according
to the following formula:
1) 100 mA can be guaranteed over the entire temperature range for the switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output". For lower
ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be
guaranteed over the entire temperature range for the "1 x PNP" current output.
2) Larger currents are supported, thus deviating from the IO-Link standard.
