Industrial safety relays and control systems

Safety relays, control systems and filter module


The small control system MSC is the solution for the logic behind your safety system. Individually configured for your machine, it can be used to implement highly diverse safety engineering applications. You can select the right modules
to meet the requirements for your installation, paying only for the functions you actually need. Protection using an MSC guarantees maximum safety according to the applicable standards.

For machines and installations that can produce a risk for people when in operation, the EU Machinery Directive defines minimum requirements that are intended to reduce to a minimum the specific hazards and the
related risks of accident.
If all sources of danger cannot be eliminated by design measures, appropriate protective measures must be taken. Using guards, such as fences or similar, it is intended to prevent personnel from entering the danger
area. If users need to have access to the danger area during operation, movable guards such as safety doors, flaps, etc., are used. This is the case, for example, for loading or unloading, troubleshooting, machine
setup or cleaning work.
To safeguard this access area, safety switches with various principles of operation are used. These switches are designed to monitor the position of the guard and, when the guard is opened, to generate a signal that will
safely interrupt the supply of power to the potentially hazardous parts of the installation or that will ensure that the safety circuits are safely interrupted. The EUCHNER safety relays series ESM ensure that the safety
circuits are interrupted. For one thing, they safely evaluate components connected such as
-- mechanical safety switches with and without guard locking,
-- non-contact safety switches,
-- emergency stop controls,
-- electro-sensitive protective equipment, etc.,
for another, they safely shut down dangerous machine functions.
The safety relays impress with their compact mounting rail housing and their suitability for applications up to category 4/PLe according to EN ISO 13849-1.
