Input-output expansion for the easyE4 series control relays with a rated operating voltage of 24 VDC. This expansion provides: analogue inputs that can be used either as voltage inputs of 0-10 V or current inputs of 4-20 mA, and analogue outputs that can be used either as voltage outputs of 0-10 V or current outputs of 4-20 mA. Connections are made via screw terminals. The connection to the easy-E4 control relay or another easy-E4 expansion is made using the easy-E4-CONNECT1 connector, which is included in the delivery. EASY-E4-DC-6AE1.
