4.3 Voltage supply
4.3.1 Supply voltage US
The US supply voltage supplies the device and IO-Link with voltage (18…30 V DC).
US also supplies the outputs and the sensors. There is a common monitoring of the current /
switching-off in case of excessive current. If excessive current is detected, the device switches
to active short-circuit protection mode Hiccup. Switching off US also switches off the voltage
supply for the outputs and for the sensors and interrupts the IO-Link communication. The device
has no additional port to supply the outputs and sensors.
4.3.2 Limit values, protection against excessive current
AL5121
Total current (US) 50...1050 mA
Total sensor supply (Pin1) max. 1 A
The total current is limited to 1050 mA. If the current is too high, the device switches off all outputs and
sets the short circuit parameter Hiccup in index 15116 until the current is within the permissible range
again.
4.3.3 Behaviour in case of undervoltage
If the supply voltage of the outputs (US) falls below 16 V, all outputs and the IO-Link communication
switch off.
4.4 Inputs/ outputs
The device has 16 ports (X1.0...X1.15). Each port has a digital input/digital output.
The device has digital type 3 inputs. Connected devices must be suitable for these inputs.
4.4.1 Digital input filters
The input signals can be changed via different filters before they are passed on via IO-Link. The
following filters are available and are applied to the input signal in this order:
1. Debounce
2. Hold
3. Inverting
Digital input
Input
debounce
Input hold Input invert
IO-Link
process data
Each of these filters can be configured separately via IO-Link. More information is available in the
IODD at documentation.ifm.com.
The device detects signals of a length of min. 2 ms. Shorter signals are not detected.
Periodic signals are only detected reliably if the signal period is at least twice as long as the
cycle time.
The precision of the digital input filters is ± 1 ms.
