Use with non-redundant encoder
• Equipotential bonding of the encoder circuit should always be at one point only (preferably encoder negative).
• Operate the two redundant modules on a common load power supply.
•
When selecting encoders, compare their properties with the specified input characteristics. Remember that this function
must always be available, regardless of whether you are using one or two inputs. Example of valid values for NAMUR
encoders: for "0" current > 0.7 mA; for "1" current > 4.2 mA.

A definite evaluation of the diagnostics information "P short-circuit" and "wire break" is not possible. Deselect these
individually in your configuration.
You cannot use the module in redundant operation for applications in hazardous areas.

• The equipotential bonding of the load circuit should always take place from one point only (preferably load minus).
• Diagnostics of the channels is not possible.
• The equipotential bonding of the load circuit should always take place from one point only (preferably load minus).
