Module
DI16xDC 24 V
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
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.
DI 8xAC 120/230V
DI 4xNamur [EEx ib]
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
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.
DI 24xDC 24 V
F-module in standard mode
DI 8xNAMUR [EEx ib]
F-module in standard mode
Redundant DO dual-channel
DO8xDC 24 V/0.5 A
A definite evaluation of the diagnostics information "P short-circuit" and "wire break" is not possible. Deselect these indi-
vidually in your configuration.
DO8xDC 24 V/2 A
DO32xDC 24 V/0.5 A
DO8xAC 120/230 V/2 A
DO 4x24 V/10 mA [EEx ib]
You cannot use the module in redundant operation for applications in hazardous areas.
DO 4x15 V/20 mA [EEx ib]
You cannot use the module in redundant operation for applications in hazardous areas.
DO 16xDC 24 V/0.5 A
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.
