ELO - Electronic Products for Automotive ELO started production of Automotive Parts in 1978 with a single item of Electronic Regulator for Alternators. Without losing its focus and desire for excellence, after 40 years ELO manufactures over 500 different products in 20 main categories. All ELO products are manufactured in Turkey and sold globally in 30 different countries. In its 40 year journey, ELO has expanded its product range parallel to sectorial growth and demand. While doing so, it has become the representative for many of the standards in the Turkish automotive spare parts industry. One of those standards is the quality standard set by ELO. All ELO products are tested above of sectorally established norms and are packaged only after they are entitled "ELO Warranty". In addition, ELO is a proud holder of IATF 16949:2016 Automotive Quality Management System Certificate. ELO identifies itself with its consumer by building a bridge of constant communication. In order to meet the needs of each consumer, ELO uses all the advantages of being a local manufacturer. Consequently, in addition to the hundreds of products in its portfolio, ELO prides itself in listening to every one of its consumers to generate tailor-made solutions. ELO invests in understanding the individual needs of each consumer for custom manufacturing as well as making modifications on existing products. This catalog consists detailed information on ELO ISO Relays. ELO ISO Relays are manufactured in three categories which are Mini Relays, Mini Power Relays and Micro Relays. All ISO Relays are available with Dust or Water Proof cover, without coil suppression or with diode and with resistor alternatives. ELO ISO Relays vary from 80 to 15 Amperes in 12 and 24 Volts. Other than ISO Relays, ELO manufactures close to hundred different relays. These relays include, but not limited to, Power Relays, Timer Relays, Glow Plug Relays, Horn Vibration Relays, Wash & Wipe Relays and many more. Besides Relays, ELO manufactures various types of Flashers, Regulators for Alternators, Oil Pressure Switches, Sockets, Converters, Inverters, Switches, Buttons, Indicator Lamps, Battery Group Products, Generator Group Products and a whole lot more. Quick Glance at the New ELO Catalog Let's take a closer look at the new ELO Catalog. How many different products are there in the new catalog? The new ELO catalog consists more than 500 different products in 20 main product categories. What are the main product categories? ELO's main product categories are: • ISO Relays • Relays • Flashers • Sockets • Regulators • Oil Pressure Switches • Converters & Inverter • Switches & Buttons & Indicator Lamps • Battery Group Products • Generator Group Products • And Other Products How do I find the product I am looking for? Products are listed according to their product code, under relevant section. What type of information are there on product pages? You will find detailed information on each product page, which include, product visuals, technical drawings, dimensions, technical information, as well as performance graphs. Cross Codes and Original Equipment Manufacturer's Codes are listed where available. Why do I see detailed introduction pages on some product group pages? We have compiled frequently asked questions for different product groups. You can find answers to those questions on introduction pages. How does the new coding system work for the ISO Relays and Sockets? We have created "speaking codes" for your convenience. With the new coding system you will never need to memorize a product code ever again. Please follow the instructions in "Relays - Product Coding System" page for more information. The same system goes for our new Sockets which is explained in "Sockets - Product Coding System" page. I see pages named "Relays - At a Glance" and "Flashers - At a Glance". What are they? These are basically charts that let you see the main technical information of all our new ISO Relays and Flashers. This way, you don't need to go over hundreds of pages looking for basic information. There is a new section called the "Accessories". Why? Almost all our Relays and Flashers have matching sockets. We did not want you to waste extra time scanning through the pages trying to match accessories to products. Therefore, we have included socket alternatives that match each of our Relays and Flashers. The Oil Pressure product pages look completely different. Why is that? ELO manufactures Oil Pressure Switches according to customers' requirements of measuring range, thread size and warning contact switch point. As of 2019, we have 221 different types of ELO Oil Pressure Switches and the number grows everyday as we get different requests from our customers. Since it would be impossible to spare a single page for each ELO Oil Pressure Switch, you will find general information on these products in ELO Oil Pressure Switch Series pages. These pages include detailed technical diagrams, connection alternatives and all other technical data. Cross Codes and Original Equipment Manufacturer's Codes are listed where available. I have other questions, what do I do? Please contact ELO Headquarters or your local representative for more information. We are always happy to hear from you.

Relays - General Information How to Choose a Relay? What is a relay? How do I choose a relay? How many different types are there? Relays are basically switches that open There are various parameters to and close circuits, electromechanically or consider when choosing a relay, There are various types of relay. electronically. They use very low currents including but not limited to, nominal Most commonly used relays to control much higher currents. voltage, maximum current, contact in automotive industry are: form, terminal layout, installation type, -Mini Relays dimensions, IP protection level, maximum ambient temperature it will -Micro Relays operate in, and many more. -High Power Mini Relays -Power Relays -Relays w/ coil suppression Relay Terminal Layouts Furthermore, relays may vary 4 Terminals 5 Terminals Changeover 4 Terminals Changeover according to; Mini Relay Mini Relay Mini Relay Micro Relay Micro Relay -Installation- w/ or w/o bracket -Contact form- Housing single, double or more contacts -Structure- Electromechanical or electronic 4 Terminals Changeover -Reaction time- Standard or Mini Power Relay Mini Power Relay Timer relays There are also relays that are designed for specific applications.

Relays - Terminology Relay Terminology - Nominal Voltage: Source voltage applied to the coil of the relay (generally 12V or 24 in vehicles). - Operating / Drop Out Voltage: Minimum voltage that enables contacts to operate / Maximum voltage that reverts contacts to unoperated state. - Maximum Coil Voltage: Maximum voltage that can applied to the coil without damaging the relay. - Coil Resistance: Ohmic resistance of the coil at a certain temperature condition. - Rated Continuous Load: Current that can be carried continuously by the relay. - Maximum Inrush Current: Maximum instantaneous current at the moment of first contact. It may be up to ten times higher than the rated continuous load. - Terminal: Point of connection for the cables carrying the input and output currents. - Terminal Connection Type: The method of connection of the cables to the terminals. - Terminal / Contact Electrical Structure: Single open contact, Single closed contact, Double (Changeover) contact, Double (Bifurcated) contact, etc. - Contact Material: In relays of quality, special silver alloys are used as contact material. The most commonly used silver alloys are AgNi0,10, AgNi0,15, AgSnO2. - Contact Distance: Contact distance is the maximum gap between the contacts, which determine the maximum voltage and life expectancy
