Safety controls

The MSI 400 configurable safety controls offer efficient solutions for integrating multiple safety sensors. Even the standard MSI 420 variant has 16 safe inputs, 4 safe outputs and 4 programmable I/Os. This makes it suitable for many safety applications.The additional configurable inputs/outputs allow the assignment to be customized to the application’s requirements. In addition, the optional extension modules allow you to expand the number of inputs and outputs flexibly to meet current and future requirements. The MSI 430 basic module with a width of 45 mm even has an Ethernet interface with Industrial Ethernet protocols. The safety control can be configured quickly and efficiently using the license‑free configuration software MSI.designer. It is easy to use and has numerous comfort functions.

Overview

MSI 400 safety controls

Compact construction and easy to configure

The compact MSI 400 safety controls evaluate the signals of a wide range of safety sensors and are used with small- to medium-sized machines for monitoring the safety circuit. With their configurable safety functions, they can very easily be adapted to the respective requirements.

Advantages for you

Always the right solution
With 2 basic modules, the MSI 400 series always offers the right solution – from standard functions to integrated gateways. All basic modules can be modularly expanded if necessary.
Saves space
24 safe I/Os and Industrial Ethernet protocols are integrated on a width of just 45 mm. This reduces the space required in the switch cabinet and simplifies ordering because there is only one part number.
Maximum switching power
Available at each output of the system is 4 A of wear-free switching power. This allows e.g. valves to be actuated directly and makes additional relays unnecessary.
Fast online diagnosis
The integrated online diagnosis and the system logbook provide a quick overview of the system status.
Possible problems can thereby be quickly localized. Solutions for remote maintenance can also be implemented without additional effort and often make expensive maintenance work unnecessary.

Highlights

Perfect start – modularly expandable

Even the MSI 420 standard module has 20 safe inputs, 4 outputs and 4 configurable IOS, making it the perfect entry-level solution for standard applications. If necessary, all MSI 400 basic modules can be expanded with the I/O extension modules to up to 116 safe inputs and 56 safe outputs. 4 A wear-free switching capacity is available at each system output. This means that e.g. valves can be controlled directly and no additional relays are required.

Integrated gateways

The MSI 400 safety controls can be integrated easily into industrial networks. With a width of just 45 mm, Ethernet interface and Industrial Ethernet protocols are already integrated.

Other gateway modules

Gateway modules are used for integration into other fieldbuses such as EtherCAT, PROFIBUS and CANopen.

Flexible connection technologies

All modules are available with either pluggable screw-type terminals or with spring-force/push-in terminals – this means even better adaptation to your installation requirements.

Removable program memory

The removable program memory in SD-card format, which can be accessed on the front side, offers large memory space for application programs. Handling of the projects is thereby simplified, saving a great deal of time during commissioning, duplication and should servicing be required. The cover fastened to the control protects the memory from unintended removal.

Always quickly connected

Integrated USB and Ethernet interfaces enable flexible access to the system. As a result, status and diagnostic information is available quickly during configuration and operation.

Optical function indicator via LEDs

All inputs and outputs of the system feature clearly assigned LED indicators located above the connections. These are supplemented with other LEDs for displaying the module status. As a result, the operating state of a system can be identified quickly and unmistakably.

Quickly to your objective with MSI.designer

With the configuration tool MSI.designer you can create projects simply and efficiently. The license-free software contains an extensive library and more than 50 certified function blocks and supports you during the creation, testing and documentation of your projects.

Intuitive configuration

With the intuitive operation, configurations are created quickly. Sensors and actuators can be used directly in the logic editor and connected to a function block in the same step. Freely definable pages and the summary of function blocks provide a good overview. Multiple logic pages can even be viewed in parallel and, with movable windows, you always see the elements that optimally support your work.

Extensive function block library

The library of the MSI.designer features more than 50 certified function blocks. Typical functions such as restart, the evaluation of two-hand controls and contactor monitoring as well as complex functions such as muting processes are already preconfigured and can be quickly implemented. Up to 300 function blocks can be integrated in one project.

Integrated simulation

The simulation function and the integrated logic analyzer allow the programmed functions to be checked right from a PC. Any necessary modifications are already performed in the office, and not in the installation area on the machine. This saves considerable time during commissioning on site.

Professional reports

The documentation function summarizes all project information in a detailed, well-structured report. The report can be configured by the user and thereby provides an important part of the directive-compliant documentation for a machine at the press of a button.

Application

Evaluation of multiple safety sensors with configurable safety functions

Requirement:
Multiple safety sensors must be integrated into the machine or system control. Functions such as a time delay for releasing a locking device or signal connections are also to be configured.

Solution:
The basic module of the MSI 400 expandable safety control already has 24 safe inputs/outputs as well as an Ethernet interface with Industrial Ethernet protocols. The safety control can be configured quickly and efficiently using the license‑free configuration software MSI.designer.

APIC_IL_PA_MLC500_SPG_Access-Safeguarding_muting_diagonal_wl_700x500px

Access guarding on conveyor lines, with muting function

Requirement:
Access guarding on conveyor lines is to prevent persons from accessing the danger zone, while at the same time allowing the transported goods to pass through.

Solution:
The muting function bridges the safety sensor in a controlled manner to allow the transported goods to pass through. Here, the special muting function modules of the MSI 400 safety control or the MSI-MD-FB muting interface, which is designed as a field module, handle the control of the muting sequence.

MSI_sichere-überwachung-pressen_700x500px

Safe monitoring of presses

Requirement:
The specific requirements on the safety of mechanical and hydraulic presses are described in standard EN ISO 16092. The implementation of these requirements and the integration in the press operating sequence are to be supported and simplified by the configuration tool.

Solution:
The MSI.designer configuration tool offers a special function library for use on eccentric and hydraulic presses. It contains tailored function blocks for the control and protection of presses and thereby makes quick and easy configuration possible.
