Relays Address New Electrical Design Challenges

Higher temperature and inrush current - improved switching performance

New applications for switching relays continue to emerge in industrial and domestic electrical circuits. Omron has responded to this trend with the launch of new devices, including new high temperature relays meeting the latest standards for cookers and heater controls, relays that tolerate high inrush currents and are suitable for low energy lighting and new versions of its most popular industrial control relay.

The new G2RL-1A-E-CV is rated for use at temperatures up to 20ºC higher than the standard type, tolerating up to +105ºC. It also offers superior switching performance with longer electrical endurance of up to 100,000 operations switching 16A at 250VAC and +105ºC.

Available in 24 different models, this PCB relay family is suitable for use in ovens, washing machines, boilers and HVAC equipment. A high sensitivity type, the G2RL-H, has a coil sensitivity of 250mW and is available with a UL 1446 Class F coil insulation system. The relays conform to VDE (EN 61810-1/EN 60255-23) and UL 508/ CSA C22.2 standards and meet VDE0700 regulations for safety of household and similar electrical appliances, with insulation according to VDE0110.

The G5RL-1A-E HR is a low profile relay (29.0mm x 12.7mm x 15.7mm), capable of handling high inrush currents such as those typically encountered in driving fluorescent or incandescent lamps in emergency lighting systems and appliance control applications. The relay is TV5 rated by UL and is approved to 100A steady-state, 10A(RMS), both at 240VAC for 50,000 operations by VDE. It is available with rated DC coil voltages of 5V, 12V, 24V and 48V, allowing 50,000 operations with a resistive load, bearing 16A at 250VAC or 24VDC.

A new quiet version of the G5RL, aimed at domestic applications ranging from panel heaters to video games, creates a Sound Pressure Level (SPL) of typically just 45dB at a distance of 15cm when switching.

Omron has also added four new versions to its G6RL family, designed for industrial and HVAC applications. The G6RL-ASI achieves double the standard switching performance through the use of silver-tin-indium contacts. It is rated for 100,000 operations at 8A, 250VAC. In its Normally Open (NO) form, the device achieves even higher performance of 100,000 operations at 10A, 250VAC.

For high inrush applications, the G6RL-PL type offers an even longer life of 250,000 operations with an inrush current of 20A and a steady current of 2A, allowing it to meet P1 load conditions for HVAC/boiler applications. The G6RL-SR shock resistant type and G6RL-1(A)4 fully sealed type complete the new product line-up.
