When it comes to electrical circuits, ice cube relays are a commonly used component. These relays are used to control the flow of electricity in an electronic circuit. They are called ice cube relays because of their small, square shape, which looks like a small ice cube. They are widely used in industrial applications, automation systems, and home automation systems. In this article, we will discuss the wiring diagram of an ice cube relay in detail, with step-by-step instructions and diagrams.
What is An Ice Cube Relay?
An ice cube relay is an electromechanical switch that is used to control the flow of electricity in a circuit. It is called an ice cube relay because of its small, square shape, which is similar to a small ice cube. It consists of a coil, which is the electromagnetic component, and a set of contacts, which are the mechanical component. The coil is energized by an electrical signal, which creates a magnetic field that moves the contacts to make or break a circuit. This makes it a versatile component in electronic circuits.
Advantages of using an ice cube relay
The use of an ice cube relay has several advantages:
- It is a low-cost solution for controlling electrical circuits.
- It is a durable device that can withstand high temperatures and mechanical shocks.
- It is available in different sizes, depending on the application.
- It is easy to install, even for non-professionals.
- It is versatile and can be used in different types of circuits.

Parts of An Ice Cube Relay
1. Coil
The coil is the electromagnetic component of the ice cube relay. It is made up of a coil of wire wound around a core. When an electrical signal is applied to the coil, it creates a magnetic field that moves the contacts of the relay.
2. Contacts
The contacts are the mechanical component of the ice cube relay. They are typically made of silver or other conductive materials. When the coil is energized, the contacts move to complete or break a circuit. There are two types of contacts: NO (Normally Open) and NC (Normally Closed).
3. Terminals
The terminals of the ice cube relay are used to connect the device to the circuit. They are typically made of metal and are located on the bottom of the device. There are two types of terminals: coil terminals and contact terminals.
4. Diode
The diode is an optional component that is used to protect the ice cube relay from voltage surges. It is located across the coil terminals and allows current to flow only in one direction.
Steps for Wiring An Ice Cube Relay
Follow these steps to wire an ice cube relay:
Step 1: Identify the terminals
Identify the terminals of the ice cube relay. There are two types of terminals: coil terminals and contact terminals. The coil terminals are typically marked “A1” and “A2”. The contact terminals are typically marked “NO” and “NC”.
Step 2: Connect the coil terminals
Connect the coil terminals to the circuit. The polarity of the coil does not matter. Connect one of the coil terminals to the positive terminal of the power supply, and the other coil terminal to the negative terminal of the power supply.
Step 3: Connect the contact terminals
Connect the contact terminals to the circuit. The NO terminal is connected to the positive terminal of the load, and the NC terminal is connected to the negative terminal of the load. If the load is an AC device, make sure to connect it to the correct phase.
Step 4 (optional): Add a diode
If you want to protect the ice cube relay from voltage surges, add a diode across the coil terminals. The cathode of the diode (the end with the stripe) should be connected to the positive coil terminal, and the anode should be connected to the negative coil terminal.
FAQ
1. What is an ice cube relay used for?
An ice cube relay is used to control the flow of electricity in a circuit. It is commonly used in industrial applications, automation systems, and home automation systems.
2. What is the difference between NO and NC contacts?
The NO (Normally Open) contacts are open when the relay is not energized, and they close when the relay is energized. The NC (Normally Closed) contacts are closed when the relay is not energized, and they open when the relay is energized.
3. Can an ice cube relay control DC and AC circuits?
Yes, an ice cube relay can control both DC and AC circuits. However, make sure to connect the load to the correct phase if it is an AC device.
4. What is the function of a diode in an ice cube relay circuit?
A diode is an optional component that is used to protect the ice cube relay from voltage surges. It allows current to flow only in one direction, which protects the coil from damage.
5. How do I know which terminal is which on an ice cube relay?
The terminals of an ice cube relay are typically marked with letters or symbols. The coil terminals are typically marked “A1” and “A2”. The contact terminals are typically marked “NO” and “NC”. Consult the datasheet of the relay to confirm the terminal markings.
