ER4374-0002 | 2-channel analog input + 2-channel analog output ±10 V or 0/4…20 mA, parameterisable, 16 bit

The ER4374 EtherCAT Box combines two analog inputs and two analog outputs which can be individually parameterised, 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 EtherCAT Box modules with zinc die-cast housing are ready for use in harsh industrial and process environments. With the fully sealed design and metal surfaces the ER series is ideal for applications requiring enhanced load capacity and protection against weld spatter, for example.
