RXMH2 type large capacity intermediate relayDetailed product description：

1 Purpose
The RXMH2 large capacity intermediate relay is used in industrial automation control and secondary circuits of power systems as an intermediate auxiliary and to expand the control range.

2 Characteristics
2.1 The number of contacts can reach up to 8, with a large breaking capacity.
2.2 Coil excitation is divided into two types: DC and AC.

3 Action principles:
The RXMH2 high-capacity intermediate relay is an electromagnetic relay. It consists of three parts: electromagnetic system, contact system, and bracket. The electromagnetic system adopts a direct acting structure with a large working stroke. The contact system adopts bridge contacts with large breaking capacity. When the coil is energized, it generates a magnetic field that attracts the iron core. The contact conversion is driven by the iron core. The shell adopts a Combiflex protruding modular insertion structure with bow I insertion.

Technical data of RXMH2 large capacity intermediate relay

4.1 Operating voltage: DC.<70% of rated voltage; AC<85% rated voltage.
4.2 Return voltage: DC.>5% rated voltage; AC>15% rated voltage.
4.3 Action time:<55ms RK223 070 specification<60ms, AC specification<65ms.
4.4 Coil power consumption: D.C. is 5.5W; A.C. is 9VA
4.5 Maximum breaking capacity of contacts: A.C. V ≯ 250V; I ≯ 10A (power factor of 0.4 ± 0.1) is 1000VA
D.C. V≯250V； I ≯ 5A, (L/R=40ms) is 100W

If the contact breaking capacity is increased, the contacts can be connected in series according to the data in Table 1.

When the voltage (DC) is 55V	20A/20A (single contact)/(double contact series)
When the voltage (DC) is 110V	6A/20A (single contact)/(double contact series)
When the voltage (DC) is 125V	5A/20A (single contact)/(double contact series)
When the voltage (DC) is 220V	1.2A/6A (single contact)/(double contact series)
When the voltage (DC) is 250V	1A/5A (single contact)/(double contact series)
