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. The latest documentation is
supplied with the unit.
Overview
The module provides 8 digital inputs, 8 digital outputs and 2 dedicated test
pulse outputs. The inputs are suitable for connecting single or dualchannel
safety-related input devices, with or without test pulses.
The inputs and outputs are driven from a SafetyBUS p-compatible PSS.
The module’s device address is established by setting the address switch
on the unit. Inputs on the module can be allocated to two I/O-groups.
There are 6 positive and 2 negative-switching 2 A outputs.
Two of the positive-switching outputs can be used in conjunction with two
negative-switching outputs (one each) to form two dual-pole outputs.
Individually, the negative-switching outputs can only be used for nonsafety-
related applications, in which it is permitted to switch to earth.
All outputs are protected against short circuit, overload and excess
temperature. They are suitable for connecting both resistive and inductive
loads. Positive-switching outputs are suitable for connecting capacitive
loads of up to 1 μF.
The PSS SB DI8O8 requires two 24 V supplies with a common earth. The
“Supply” feeds the module electronics and dedicated test pulse outputs.
The “Load Supply” feeds the outputs.
The module is galvanically isolated from SafetyBUS p via optocouplers.
