The modular system is formed around basic units, Which are equipped with additional functions by means of modules. In addition to basic unit contacts, top-mounted auxiliary contact modules o... Read more
Electronic equipment such as programmable logic controllers (PLCs), timing relays and coupling modules that can be affected by other components on ship electric network, are commonly used wi... Read more
The contacts of electromechanical devices on ship electrical system are utilized through control circuitry only are unlikely to sustain currents higher than 10 Amps. They are called control... Read more
Electromechanical relays can be expensive, large, take longer to work than modern semiconductors and have a finite contact life, particularly for large power contactor relays on big ship ele... Read more
A reed relay consists of a reed switch, ie a sealed glass capsule containing two separated overlapping ferromagnetic reeds. A typical reed switch capsule. The capsule is surrounded by an ele... Read more
Latching relays allow the circuit to be controlled by using a single pulse to the relay control circuit and are used when a relay is required to maintain its position if the power is interru... Read more
The relay is an electro-mechanical switch, consisting of a coil, an armature, and contacts. A current passes through the coil creating a magnetic field that attracts the armature, causing th... Read more
Contactor and relay terminal markings should conform to DIN EN 50005 standard. The markings make it possible to determine the terminals that are associated with the ship component, ie functi... Read more
Overload relays protect motors from overheating, eg by machinery being overloaded or an open phase In a three-phase system.The relay will open and disconnect from the power source when too h... Read more
Coils are used in a variety of electromagnetic starters, relays and contactors. Letters are used to Identify the coil. For example, -KM would indicate a motor starter while -K indicates both... Read more
