The safety module is an output module from the Inline product range and is used in an INTERBUS-Safety system.
The safety module can be used as a part of an Inline station at any point within an INTERBUS-Inline system. The transmission speed of the safety module can be set to 500 kBaud or 2 Mbaud using a switch. Only one transmission speed must be used uniformly within an INTERBUS system.
This module has four safety relays that can be operated with single or double-channels depending on the parameters.
The parameters of the relay outputs can be set in accordance with the application and make it possible to integrate actuators in the safe INTERBUS (INTERBUS-Safety).
The safety-related segment circuit can be switched on or off using suitable wiring.
When the output is switched off, the supply to the downstream modules is disconnected safely.
The module also has two clock outputs with allocated alarm inputs
to monitor external contact extensions.
In an INTERBUS-Safety system, you can achieve the following safety integrity by using the safety module depending on the installation and parameterization:
- Up to category 4 according to the EN 954-1 standard,
- Up to SIL 3 according to the standards EN 61508 and EN 62061,
- Up to PL e according to the prEN ISO 13849-1 standard.
The output data is exchanged between the safe
INTERBUS controller and the module using safe messages (see
UM DE INTERBUS-SAFETY SYS).
