1 Purpose
The RXSF1 double drop type signal relay is used for fault indication and alarm in secondary circuits of power systems and industrial automation control circuits.
2 Characteristics
2.1 The relay has a small volume and is equipped with two independent signal relays in the smallest installation housing
2.2 The signal board displays clearly, and each relay has three sets of contacts.
The nameplate on the relay can be detached, so the required text can be printed.
3 Principles of Action
The RXSFl type dual element signal relay is equipped with two independent signal relays in a minimum housing. This relay is an electromagnetic snap on structure, consisting of three parts: electromagnetic system, contact system, and signal display. When the relay is activated, the signal board naturally drops due to gravity and is displayed as four horizontal bars. There are two colors available: red and yellow fluorescent, with clear display and wide viewing angle. When the signal disappears, the contact naturally returns, and the signal board has two types: manual return and automatic return. The shell adopts the imported Combiflex protruding modular insertion structure.
