RXMA1 type intermediate relayDetailed product description：

The RXMA1 intermediate relay is used in power system secondary circuits and industrial automation control circuits as an intermediate auxiliary to expand control circuits.

2 Structural Features
2.1 It can provide up to 7 pairs of dynamic closing or breaking and conversion contacts, with a compact structure.
2.2 The contact action can be tested by moving the armature through the small hole on the cover.
2.3 There are two types of coil excitation: AC and DC.

3 Principles of Action
The RXMAl intermediate relay is an electromagnetic snap on structure, consisting of an electromagnetic system and a contact system. When the coil is powered on, a magnetic field is generated by the iron core to attract the suction plate, which drives the spring to switch the contact circuit. The contact adopts dual contact, which has the advantages of low contact resistance, strong contact reliability, and large breaking load capacity. The inertia of the absorber design is very small, so this relay can withstand a certain amount of shock and vibration, and can withstand the impact of moderate seismic waves. The relay housing adopts the imported Combiflex structure.
