The reliability of industrial automation equipment is increasing with the electronic model

Blocks are becoming more important as they become more widely used.

Modern relay or solid state relay interface plays an important role

desired role. Regardless of the electrical equipment of the machine during the production process

equipment, or energy transmission and distribution, manufacturing automation and materials processing

In industrial control engineering, the main purpose of relays is to ensure

Signal exchange between the process periphery and the higher-level central control system.

This exchange must ensure reliable operation, isolation and electrical cleanliness

Clear. Safe electrical interfaces in line with modern control concepts are required

Has the following characteristics:

– Can achieve level matching of different signals

– Safe electrical isolation between input and output

– Powerful anti-interference function

In practical applications, relays are usually used in these situations

Used in: flexible interface configuration requirements, large switching capacity or

The latter requires the use of multiple contacts in combination. Relay is more important

feature is:

– Electrical isolation between contacts

– Switch operation of various independent current circuits

– Provides short-term overload protection in the event of short circuit or voltage spikes

– Combat electromagnetic interference

– Easy to use

Solid state relays are commonly used as process peripherals and electronic devices

The use of interfaces between devices is mainly due to the following requirements:

– Micro controlled power

– High switching frequency

– No wear and contact collision

– Insensitive to vibration and impact

– Long working life

Relays are electrically controlled switches that perform many functions in automation. When it comes to switching, isolating, monitoring, amplifying or multiplying, we provide support in the form of clever relays and optocouplers. Whether solid-state relays, electromechanical relays, coupling relays, optocouplers or time relays and logic modules, you will find the right relay for your application here.
