Test Pulse Outputs/24 Vdc Terminals; Schematic Internal Wiring Diagram - Pilz PSS SB DI16 Operating Manual

Test pulse outputs/24 VDC terminals

The four test pulse outputs T
as 24 VDC terminals. The test pulses are suitable for testing the wiring of
input devices. Only inputs which operate in accordance with the zero
signal principle (on switching off) are permitted for safety-related
applications.
Test pulses are allocated to inputs via the configurator in the programming
device.
Each test pulse output has four terminals, which are divided into two
terminal pairs. If a terminal pair is not being used for a test pulse it can be
used instead as a 24 VDC terminal. The use of terminal pairs is also
established via the configurator in the programming device. All terminals
are configured as 24 VDC terminals in the default setting.
Each terminal pair has a maximum load capacity of 0.5 A, irrespective of
its use.
