interface, the Opto I/P can be assigned to any function from I/O configuration menu. The function can
be assigned to any input by entering the values to them either 0 or 1 i.e. 0 = not assigned and 1 =
assigned.
The following are the list of functions, which can be assigning to digital input.

The digital inputs are suitable for accepting AC or DC auxiliary supply. The selection for AC or DC
auxiliary supply is done from submenu Opto I/P under SYSTEM DATA menu.
The DI can be selectable for different operating voltage (ordering option) depending on the application
requirement.
For details regarding the operating voltage and its threshold values, please refer to the Technical
Specification section of this manual.

Output Relays

The device supports 6 numbers of relay output. The use of these relay outputs depends on the
application. There are a number of settings associated with the relay outputs.
2.6.1

Output Relay Function Assignment

The relays have configurable logic outputs, which can be assigned to any available function. The logic
outputs are identified as RL1 to RL6. All logic outputs have changeover contacts and can be
configured to change state on activation of the different functions available in the relay. A basic output
matrix is included in the P50 Agile configurator. Different functions can be assigned by using P50
Configurator as well as relay user interface. On the user interface the output relays can be assigned
