Input/output extension for the control relays of the easyE4 series with a rated operating voltage of 24 VDC. This extension provides: 4 analog inputs that can be used either as voltage inputs (0-10V) or current inputs (0/4-20mA) and 2 analog outputs that can be used either as voltage outputs (0-10 V) or current outputs (0/4-20 mA). The connections are made using push-in terminals. The connection to the control relay or another extension of the easyE4 series is made using the EASY-E4-CONNECT1 connector (item 197225) which is included in the scope of delivery.
