ABB UFC719AE01 3BHB003041R0001 3BHB000272R0001 Processor Module Building an industrial automation system with many components from different suppliers is no easy task. Securing each individual component that enters a system, as well as the system as a whole, can make an already challenging task even more painful. IEC 62443-4-2 certification for highly customizable host devices ensures that your open edge computing platform is secure by design.

ABB UFC719AE01 3BHB003041R0001 3BHB000272R0001 Processor Module Large industrial enterprises, system integrators and independent software vendors all have their own unique pain points when building industrial automation systems. This white paper discusses the particular security challenges faced by these stakeholders and recommends specific best practices for adopting IEC 62443-4-2 host devices as secure IIoT edge computing gateways for industrial automation systems.

The electromagnetic switch is operated by a small current, and a large current is switched on or off by releasing or retracting the armature contact, thus cutting or closing the circuit. Relays are necessary when there must be electrical isolation between the controlled circuit and the control circuit, or when multiple circuits need to be controlled by a single signal. The relay is an electromagnetic switch; Thus, its heart is the electromagnet, powered by a small current that acts as a lever or the switch itself. This makes it possible to allow relatively small currents to influence and control much larger currents. Sensors are sensitive devices, and they only produce a small amount of current, but in order for a sensor to drive a larger device, it needs something to turn the device on by allowing a larger flow of current. Like, the sensor can act as a control input to the relay, and when it is activated, a greater current flows to the device. For example, light or light sensors can be assigned to control lights outside so that when it gets dark outside, the light sensor activates a relay that acts as a light switch.
