Power Relays, Over 2 Amps: G7L-1A-P-80-CB DC48 overview

The G7L-1A-P-80-CB DC48 from Omron is a high-performance power relay designed for motor control, instrumentation, and other specialized applications. It is a two-wire relay with a silver cadmium oxide contact element and an isolation rating of IP20. The DC48 has a coil voltage rating of 24-48V, and a contact rating of 8A at 250VAC. The G7L series power relay has a minimum-rated lifetime of 100,000 operations, and utilizes a mounting hole for easy installation. Additionally, its compact size (45.6 x 48.5 x 23.5 mm) allows it to fit a variety of applications. The DC48 has a wide range of features, such as low-resistance circuits, high-speed switching, high surge currents, improved magnetic properties, and a wide operating temperature range. Additionally, it supports both standard operation reliability and long-term reliability, allowing it to meet the most demanding requirements in terms of surge currents, voltage overloads, and harsh applications.

Application Field and Working Principle

The G7L-1A-P-80-CB DC48 is ideal for motor control, instrumentation, and other control applications, such as panel lamps, fans, air compressors, contactors, and ventilation systems. Additionally, it is suitable for the control of pumps, air conditioners, and heating systems. The G7L-1A-P-80-CB DC48 works by utilizing a contactless transfer system, which allows it to switch on power with minimum jitter or noise. When the voltage is applied to the coil, the current creates an electromagnetic field, which attracts a ferromagnetic material to move onto a contact surface. As the magnet moves, it causes a physical change in the contact surface, thus breaking the circuit and allowing current to flow. The working principle of the G7L-1A-P-80-DC48 is also influenced by its cadmium-oxide contact element, which acts as a high turn-off switch. Unlike more conventional contacts, this contact element ensures more reliable operation, and a much higher degree of contact reliability over a wide range of temperatures. Additionally, the DC48 is designed to reduce contact voltage drop, making it the ideal choice for applications where power-loss prevention is of paramount importance. The G7L series of power relays also features a robust signal system, which allows for the detection of small voltage changes. As a result, it can be used for remote-control systems, and for the detection of current and voltage spikes.

Other Features

The G7L-1A-P-80-CB DC48 has a range of additional features, such as two LED indicators for adjustment and monitoring, and a jumper terminal for standard wiring. Additionally, it includes surge protection, overcurrent detection, EMC protection, and a variable speed control circuit. All these features make the DC48 a very reliable and versatile power switch, suitable for a variety of applications. In addition, the G7L series is also incredibly easy to use, with a built-in set of adjustable parameters. This allows users to customize the operation of the switch to their specific requirements and ensure optimum performance. Finally, the DC48 is highly energy-efficient, with a power consumption of less than 1 watt while switching. This makes it an ideal choice for applications where energy consumption is highly important.
