The Omron G2R-2 24VDC is a general-purpose monostable electromechanical power relay with a 24 V DC coil and two changeover poles in a DPDT (2 CO) arrangement. It has eight straight pins and can be mounted directly on a printed circuit board (PCB) or inserted into a compatible socket.
For control-panel installations it can, for example, be used with a compatible DIN-rail socket for 2-contact relays, allowing the wiring to remain on the socket and the relay to be replaced without desoldering.
The 24 V DC coil has a rated current of 21.8 mA and an approximate power consumption of 0.53 W. Coil resistance is 1 100 Ω at 23 °C with a tolerance of ±10 %. The must-operate voltage is no more than 70 % of rated voltage and the must-release voltage is at least 15 %. At 23 °C, the specified maximum coil voltage is 170 % of rated voltage and should not be interpreted as the nominal operating voltage.
Switching capacity depends on load type. With a resistive load, the contacts are rated at 5 A at 250 V AC or 5 A at 30 V DC. With an inductive load, the ratings are 2 A at 250 V AC with cos φ = 0.4 and 3 A at 30 V DC with L/R = 7 ms. The 5 A figure must therefore not be interpreted as a rating that applies indiscriminately to every type of load.
The contacts use a cadmium-free silver alloy. The relay provides 5 kV AC dielectric strength between the coil and contacts and 3 kV AC between contacts of different polarity. It can operate from −40 °C to 70 °C and the DC-coil version has a minimum mechanical endurance of 20 000 000 operations.
Le Omron G2R-2 24VDC est un relais électromécanique de puissance à usage général et à fonctionnement monostable, équipé d'une bobine de 24 V CC et de deux contacts inverseurs DPDT (2 CO). Cette version possède huit broches droites pour montage direct sur circuit imprimé (PCB) et un boîtier protégé contre les flux de soudure.
La capacité de commutation dépend du type de charge. Sous charge résistive, les contacts acceptent 5 A sous 250 V CA ou 5 A sous 30 V CC. Sous charge inductive, les valeurs nominales sont de 2 A sous 250 V CA avec cos φ = 0,4 et de 3 A sous 30 V CC avec L/R = 7 ms. La valeur de 5 A ne doit donc pas être interprétée comme une capacité applicable indistinctement à tout type de charge.
La bobine présente un courant nominal de 21,8 mA, une résistance de 1 100 Ω et une consommation d'environ 0,53 W. La tension d'enclenchement est au maximum égale à 70 % de la tension nominale et la tension de retombée est au minimum égale à 15 %. À 23 °C, la tension maximale de la bobine correspond à 170 % de la tension nominale ; cette valeur représente le maximum dans une plage variable de tension d'alimentation et ne constitue pas une tension admissible en continu.
Le relais offre une rigidité diélectrique de 5 kV CA entre la bobine et les contacts et de 3 kV CA entre contacts de polarité différente. Il peut fonctionner entre −40 °C et 70 °C. Lorsque plusieurs relais sont montés côte à côte sur un PCB, Omron indique un espacement minimal général de 5 mm afin de limiter les interactions thermiques, bien que cette contrainte puisse ne pas être nécessaire selon les conditions de fonctionnement. L'orientation de montage sur le PCB n'est pas imposée.
