Page 5: Introduction
PSS SB DI8O8 Introduction This shortform explains the function and operation of the decentralised input/output module PSS SB DI8O8. The documentation is intended for instruction and should be retained for future reference. Validity of the documentation The PSS SB DI8O8 documentation is valid from Version 2.1 onwards. It is valid until new documentation is released. -
Page 6: Intended Use
NOTICE Before installing the module you should read and consider the “PSS SB DI8O8 Installation Manual” and the “SafetyBUS p System Manual”. Intended use The PSS SB DI8O8 is a decentralised input/output module which has been designed for use as an input/output device on SafetyBUS p. System requirements CPU versions The PSS SB DI8O8 is supported by all SafetyBUS p-compatible safety... - Page 7 PSS SB DI8O8 1: Switch for setting the device address on SafetyBUS p 2: Labelling strip for the I/Os 3: SafetyBUS p interface 4: LEDs for operating status and supply voltage 5: Status LEDs for the I/Os 6: Terminal block for dedicated test pulses 7: Terminal blocks for I/Os 8: Connection terminal for the functional earth 9: Terminal block for the supply voltage...

Page 8: Functions
Functions Inputs The inputs are suitable for connecting single and dual-channel input devices, with or without test pulses. Input signals must show a “High” of 24 VDC (+15 ... +30 VDC) and a “Low” of 0 VDC (-3 ... +5 VDC). All inputs have input filters. Input status is transmitted to the CPU on the PSS master via SafetyBUS p. -
Page 9: Signal Change Behaviour
PSS SB DI8O8 : Pulse length for guaranteed signal detection for “1” or “0” signals (> Event Timeout) : Max. pulse length for pulse suppression on “1” or “0” signals (500 µs) Signal change behaviour If a signal change occurs at an input, the module will send an Event Telegram. -
Page 10: Outputs
Outputs 8 digital outputs are available on the module: • O ... O are positive-switching (“Load Supply”) 2 A outputs • O and O are negative-switching (“Ground”) 2 A outputs Positive-switching outputs are suitable for connecting resistive and inductive loads of 2 A maximum. They have an integral discharge circuit which means they are also suitable for connecting capacitive loads of up to 1 µF. - Page 11 PSS SB DI8O8 WARNING! When wiring an output with capacitance, you must be aware of the following: • An output that is switched off is tested by switching it on each cycle, approx. once every 2 minutes. • The pulse length of a switch-on or switch-off test is 200 µs •...

Page 12: Test Pulse Outputs
If the plant is sensitive to the fast on/off switching of the output test, individual outputs may be excluded from the test through the configuration. NOTICE In the case of outputs that are excluded from the output test, the PSS checks that their switch status is correct but does not check their actual ability to switch. -
Page 13: Schematic Internal Wiring Diagram
Operation of the module on SafetyBUS p The connection to SafetyBUS p is made via a male 9-pin D-Sub connector. Fibre-optic couplers from Pilz (like PSS SB SUB-D F0) can be connected to the SafetyBUS p interface. To enable the module to operate on SafetyBUS p, it must be given the device address set via the configurator in the system software. - Page 14 Test Test Load Supply Ground (2-channel) 6,6 nF Ground Load Supply 3,3 nF 2,4 M Supply Supply 24 V Schematic internal wiring diagram of the PSS SB DI8O8 Operating Manual Artisan Technology Group - Quality Instrumentation ...

Page 16: Display Elements
Display elements LEDs for status display Each input and output is assigned an LED for status display. If the input or output is high, the corresponding LED will light. If it goes low, the LED will go out. LED “Supply” Indicates that the supply is present. -

Page 18: Commissioning
Commissioning General guidelines are given below, but you should always refer to the “PSS SB DI8O8 Installation Manual” (this is part of the “Safety BUS p” System Manual and is also enclosed with every Safety BUS p-compatible PSS): • Install the module INFORMATION If the module is attached to an earthed DIN rail, this will automatically cover the module's functional earth requirements. -
