A JS1-4V power relay is designed to switch large electrical loads, either AC or DC, at voltages exceeding 2 amps. The relays are commonly used in a variety of applications, including motor control, machine automation, process control, and HVAC/R. The JS1-4V relays offer a reliable control solution in these applications with durable construction, operational efficiency, and easy connection.

The JS1-4V relays are configured for either a “make” or “break” function, which determines whether the contact is open or closed when the load voltage is applied. The “make” function allows the contact to close, and the “break” function allows the contact to open. The relays offer a range of switching voltages up to 10 amps, allowing applications in environments with a wide range of electromagnetic interference (EMI) noise and surge protection.

The relays come with a range of accessories for controlling and monitoring the switching operation of the relay. These include a variety of multifunctional timing and digital output relays, as well as a dual-on-delay timer for switching between two different time intervals. The accessory modules are designed to provide more precise and reliable control of the contact operation of the relay, allowing for better accuracy and repeatability.

The JS1-4V relays are constructed with a rugged shell and contact block that can withstand high vibration, dust, and oil. The contact block features precision-ground contacts for reliable use in industrial applications, and an adjustable contact gap that can be adjusted to accommodate different loads. The contact block is also designed with a fail-safe feature to prevent accidental switching of the contact.

The working principle of the JS1-4V relay is based on a simple electrical circuit composed of a normally open and a normally closed contact. When the relay is energized, the contact closes, allowing the current to flow. This causes the contacts to pull together, and the relay will be switched on. When the current is reduced, the contacts will separate, and the relay will be switched off. A timer, if used, controls how long the contact remains closed to ensure the load is not over-powered.

The JS1-4V relay is a reliable and efficient control solution for a variety of industrial and HVAC/R applications. With a robust construction and adjustable contact gap, it offers precise control of the contact operation. The accessories and timers provide further precise control and monitoring over the switching operation. With its reliable switching performance and wide range of voltages, the JS1-4V relay is a great choice for applications needing reliable and repeated control of large electrical loads.
