Connection Data - Endress+Hauser Ceraphant PTC31B IO-Link Operating Instructions Manual

Electrical connection
1) For switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output", 100 mA can be guaranteed over the entire temperature range. For lower ambient
temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. For switch output "1 x PNP",
200 mA can be guaranteed over the entire temperature range.
2) Deviating from the IO-Link standard, larger currents are supported.

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
≤ 60 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.

6.2.2 Load (for devices with analog output)
In order to guarantee sufficient terminal voltage, a maximum load resistance R
line resistance) must not be exceeded depending on the supply voltage U
unit.
The maximum load resistance depends on the terminal voltage and is calculated according
to the following formula:
