6ES7 321-1BH02-0AA0
In some system states, it is possible that an incorrect value of the first module is read in briefly when the front connector of
the second module is removed. This is prevented by using series diodes like those shown in figure C-3.
DI32xDC 24 V
6ES7 321-1BL00-0AA0
In some system states, it is possible that an incorrect value of the first module is read in briefly when the front connector of
the second module is removed. This is prevented by using series diodes like those shown in figure C-4.

You cannot use the module in redundant operation for applications in hazardous areas.
Use with non-redundant encoder
•
You can only connect 2-wire NAMUR encoders or contact makers.
•
Equipotential bonding of the encoder circuit should always be at one point only (preferably encoder negative).
•
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 > 0.2 mA; for "1" current > 4.2 mA.
DI 16xNamur
6ES7321-7TH00-0AB0
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.

•
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.
