The EPI4374-0002 IO-Link box combines two analog inputs and two analog outputs which can be individually parameterized, so that they process/generate signals either in the -10…+10 V or the 0/4…20 mA range. The resolution for the current and voltage signals is 16 bit (signed).

The voltage or output current is supplied to the process level with a resolution of 15 bit (default), and is electrically isolated. Ground potential for the two output channels is common with the 24 V DC supply.

 

The EPI4374-0002 is a Class B device, a 5 wire cable is required for connection.
