Connection possibilities
Fieldbus connection
PROFIBUS-DP connection
At the SDPX-IOL4-0001, the connection to PROFIBUS-DP is realized via two M12-connec-
tors.
Supply voltage
The connection of the supply voltage is done via 4-pole M8-connectors at each module.
operating voltage U
B
The 24 VDC operation voltage U
B
is used to supply the fieldbus (termination), the processor
logic, the IO-Link ports as well as the sensors.
The operation voltage is galvanically isolated from the fieldbus (ASIC).
load voltage U
L
The load voltage U
L
is not used in the module but only monitored and provided for eventual
transmission.
M12-connector for IO-Link
The connection of a maximum number of 4 IO-Link sensors is done via PIN 4 of each of the
4 M12-female connectors on the SPDX-IOL4-0001.
PIN 2 of each female connector can be used to connect simple pnp-inputs.
In case of more complex sensors, PIN 2 can for example be used as an input for a sensor
switching point.
