Generalized information in the I/O Analog Manual

The I/O Analog Manual contains information for all analog I/O products from Beckhoff. Therefore, not all information applies to EPP3356-0022.

There are deviations in the following points in particular:

  • The EPP3356-0022 only supports the 4-wire connection. A 6-wire connection is not possible.
  • The reference voltage is generated in the EPP3356-0022 from UP and is 10 V. Do not apply an external reference voltage.
