Devices with their own dedicated power supply can also be connected. Connect the reference
pole of the external power supply to the L- reference pole of the input.
The safe state of an input is indicated by a 0 signal being passed to the user program. If the test
routines detect a fault in the digital inputs, a 0 signal is processed in the user program for the
defective channel. When a fault occurs, the inputs are switched off (0) and the FAULT indicator
is activated.
Follow the closed-circuit principle for external wiring when connecting sensors. To create a safe
state in the event of a fault, the input signals revert to the de-energized state (0). Although the
external line is not monitored, a wire break is interpreted as a safe 0 signal.
Digital Input Terminals
Terminals accommodate wires up to 1.5 mm
2
(16 AWG). See the terminal torque specifications
on page 14 . Digital inputs (DI) are connected to these terminals.
