Lockout relays are essential components in many industrial control circuits. They help to prevent equipment damage and operator injury by providing a safe and reliable means of shutting down a system in the event of a fault or emergency. One type of lockout relay that is commonly used in industrial applications is the 86 lockout relay. In this article, we will discuss the 86 lockout relay wiring diagram and its functions in detail.
What is a Lockout Relay?
A lockout relay is a type of relay that is used to shut down a system in the event of a fault or emergency. It is often used in conjunction with other control devices, such as limit switches, pressure switches, or temperature sensors, to provide a reliable means of protecting equipment and personnel from harm. Lockout relays typically have two sets of contacts that are wired in series with the power source and load. When a fault or emergency occurs, the lockout relay contacts open, interrupting the circuit and shutting down the system.
What is an 86 Lockout Relay?
An 86 lockout relay is a specific type of lockout relay that is commonly used in industrial control circuits. It is designed to provide a high level of protection for electrical equipment and personnel by shutting down a system in the event of an emergency. The term “86” refers to the ANSI device number for the lockout relay, which is used to identify it in wiring diagrams and schematics.
86 Lockout Relay Wiring Diagram
The wiring diagram for an 86 lockout relay is relatively simple. The relay typically has six terminals, which are labeled as follows:
| Terminal | Description |
|---|---|
| 1 | Coil+ |
| 2 | Coil- |
| 3 | NO Contact |
| 4 | NC Contact |
| 5 | Common Contact |
| 6 | Common Contact |
The wiring diagram for an 86 lockout relay is shown below:
As you can see from the diagram, the 86 lockout relay is wired in series with the control circuit. The contacts of the relay are normally closed (NC) and open (NO). When the relay coil is energized, the contacts change state, breaking the circuit and shutting down the system.
FAQ
What is the purpose of an 86 lockout relay?
The purpose of an 86 lockout relay is to provide a reliable means of shutting down a system in the event of a fault or emergency. It is commonly used in industrial control circuits to protect electrical equipment and personnel from harm.
How does an 86 lockout relay work?
An 86 lockout relay works by interrupting the control circuit when a fault or emergency occurs. The relay is wired in series with the control circuit, and its contacts are normally closed. When the relay coil is energized, the contacts open, breaking the circuit and shutting down the system.
What are the common applications of an 86 lockout relay?
86 lockout relays are commonly used in a variety of industrial applications, such as power plants, chemical plants, and manufacturing facilities. They are often used in conjunction with other control devices, such as limit switches, pressure switches, or temperature sensors, to provide a high level of protection for electrical equipment and personnel.
What are the benefits of using an 86 lockout relay?
The main benefits of using an 86 lockout relay are increased safety and protection for electrical equipment and personnel. By providing a reliable means of shutting down a system in the event of a fault or emergency, the lockout relay helps to prevent equipment damage and operator injury. This can result in reduced downtime, lower maintenance costs, and improved productivity.
How do I choose the right 86 lockout relay for my application?
When choosing an 86 lockout relay for your application, it is important to consider factors such as the voltage and current ratings of the circuit, the type of load being controlled, and the environmental conditions of the installation. You should also consult with a qualified electrician or engineer to ensure that the relay is properly sized and installed for your specific application.
