Automotive electromechanical relays are a specialized class designed to operate in temperature extremes, high vibration locations, and have gas and chemical ingress protection. Features may include built-in diodes or resistors, hermetic seals, flux protection or added dust and water ingress protection. Coil types are single or double latching or non latching DPST, SPDT, and SPST contact forms.
Contactors (Electromechanical) are a device which turns a large load on or off using a smaller control signal. The contact rating is 6A, 8A, 9A, 10A, 12A, 14A, 15A, 18A, 20A, 22A, 24A, 25A, 26A, 30A, 32A, 35A, 40A, 50A, 60A, 62A, 65A, 70A, 74A, 75A, 80A, 85A, 90A, 100A, 110A, 120A, 130A, 135A, 150A, 160A, 176A, 185A, 200A, 225A, 250A, 265A, 300A, 330A, 350A, 400A, 500A, 600A, or 1000A.
Contactors (Solid State)
Contactors (Solid State) are a device, with no moving parts, which turns a large load on or off using a smaller control signal. The output types are AC, AC/Proportional Control, AC/Zero Cross, and DC with a load current of 1.5A, 2A, 2.4A, 4.2A, 5A, 5.3A, 5.8A, 6.2A, 7.6A, 9A, 13A, 15A, 16A, 18A, 20A, 23A, 25A, 27A, 28A, 30A, 35A, 37A, 40A, 42A, 43A, 45A, 50A, 60A, 65A, 66A, 95A, 120A, 150A, and 160A.
High Frequency (RF) Relays
High frequency and RF (radio frequency) relays are high switch speed, high reliability and RF insulated relays designed for use in computers, testing equipment and radio broadcast systems. Additional features may include an internal diode, magnetic shielding and hermetic seals. These surface mount and through-hole relays are differentiated by operate and release time, coil current and contact rating. Contact forms include DPDT, SPDT and SPST configurations.
I/O Relay Module Racks
Products in this family are interconnect devices used to create an interface between one or more I/O relay modules and an installation's fixed wiring in order to ease replacement of worn or damaged relays, and/or to incorporate such relays at the juncture between a control signal bus and field wiring. They are used primarily to provide isolation when connecting devices powered from different sources and operating at different potentials to a common control system in an industrial environment.
I/O Relay Modules
I/O relay modules are used in industrial control, building management, and similar applications to connect control equipment to input sources such as limit switches or proximity sensors, as well as output devices such as motors or linear actuators. Typically implemented in form factors that allow ease of replacement, their primary purpose is to allow system components operating at different voltage levels and supplied by different sources to be safely connected to a shared control system.
Power Relays, Over 2 Amps
Power Relays over 2 Amps are an electromechanical device which turns a large load on or off through the use of a smaller control signal. The contacts on these devices have a rating of 2 A, 3A, 3.5A, 4A, 5A, 6A, 7A, 7.5A, 8A, 8.5A, 9A, 10A, 11A, 12A, 14A, 15A, 16A, 18A, 20A, 21A, 23A, 25A, 26A, 30A, 31A, 32A, 33A, 35A, 40A, 48A, 50A ,60A, 90A, 100A, 120A, 150A, 200A, 400A, and 750A.
Products in this family are interconnect devices used to establish an intermediate, semi-permanent connection between the wiring in a system and a switching device such as an electromechanical relay that is likely to require service or replacement during the service life of the system. Throughout the use of such devices, the time, effort, and skill level required to replace worn or damaged components can be reduced significantly in the event that such service becomes necessary.
Products in the safety relay category include a variety of device types designed to enhance or accommodate human safety interests in some way. They include standard relay types with force-guided contacts, industrial automation safety relay products that provide for verification of contact state, and relays designed to accommodate electrical interfacing between hazardous (e.g. potentially flammable or explosive atmosphere) and non-hazardous areas within a working environment.
Signal Relays, Up to 2 Amps
Signal Relays Up to 2 Amps are an electromechanical device which turns a large load on or off through the use of a smaller control signal. The contacts on these devices have a rating of 10mA, 50mA, 200mA, 250mA, 400mA, 500mA, 1A, 1.25A, and 2A.
Solid State Relays
Solid-state relays (SSRs) are optically isolated electronic switching devices that switch on or off when a small voltage is applied across control input terminals. SSRs are similar to chassis, DIN rail, socket and board mount electromechanical relays designed to switch either AC or DC loads up to 660 volts but are semiconductor based and have no moving parts. They are selected by load voltage, current ratings, and switch circuit configurations such as SPST, SPDT, DPST and 3PST.
