To disconnect press the orange pusher using a suitable tool.
To open the push-in terminals IO-Link use a 2 mm wide micro screwdriver.
As soon as the supply module is supplied with voltage, the device closes the contacts
connected to terminals 13 and 14. If a fault occurs at one (or several) of the connected
channels, the device opens the contacts again.
6.1 Supply, feedback and potential modules
In combination with GND potential modules (DF311x) the GND supply modules (DF310x) are used to
reduce wiring.
In order to avoid that subsequent modules are disconnected from the voltage supply when opening a
contact lever, a feedback module (DF3210) can be used to ensure that the respective modules are still
supplied with power.
A LOAD potential module (DF320x) is used to 24 V DC circuit protection outputs to other
connections.
