Electronic control relay easyE4 with a rated operating voltage of 24 VDC. Digital inputs with 24 VDC are available, some of which can also be used as analog inputs and fast counter inputs. The control relay features transistor outputs for 24 VDC. The easyE4 control relay is equipped with diagnostic LEDs, a clock, an integrated Ethernet interface, and Push-In terminals. The easyE4 control relay can be expanded with digital input-output extensions from the easyE4 series and with communication modules.
