DIN Rail

The term “DIN Rail” derives from the original specifications published by Deutsches Institut für Normung (DIN) in Germany, which were subsequently adopted as European (EN) and International (IEC) standards. The original concept was developed and implemented in Germany in 1928 and evolved into the present standards in the 1950s.

The DIN Rail is the preferred mounting solution for electrical equipment of all types, including UL508A Control Panels. Although very simple in design, DIN rails hold together critical electrical components and are often essential to the successful installation, maintenance, and operation of electrical equipment.

Peerless Electronics carries DIN Rails from industry-recognized suppliers, Altech and TE Connectivity/Entrelec. We keep DIN Rails in stock and ready to ship 24/7 to complement electrical component mounting across industries.

Questions about DNI Rails? Contact us to speak to one of our DIN Rail specialists today.


What is a DIN rail power supply?

A DIN rail power supply is a switched-mode power supply that regulates electrical equipment voltage by converting it from an unstable input to a stable output. This particular power supply uses the DIN Rail as the mounting interface between the power supply other equipment, such as a control panel or cabinet, hence the use of DIN Rail in the name.

How do you wire a DIN rail power supply?

There are three ways to wire a DIN Rail Power Supply unit which are screwing in the wires, pushing in the wires, and clamping the wires.

How do you mount a DIN rail?

A DIN rail mounts to flat surfaces with screws inserted into the pre-drilled or pre-punched holes at the base of the rail.

What are DIN rail terminal blocks?

This terminal block is a simple device mounted to a DIN rail and used to connect the control wiring (PLCs, relays, contactors, etc.) to the field wiring.

What are the power supply connectors?

Power supply connectors are electromechanical components that bridge the electrical power source and electrically operated equipment or devices. They are most often connected via pins or plugs and are commonly called jacks.

What is the difference between SMPS and UPS?

The main difference is how they operate. The SMPS (Switched Mode Power Supply) voltage varies by constantly switching the electrical source on and off as dictated by the voltage needed at the output. UPS (Uninterrupted Power Supply) provides a constant voltage, even when the power source has stopped supplying power.

How many types of SMPS are there?

There are four types of SMPS: DC-DC Converter, Forward Converter, Flyback Converter, and Self-Oscillating Flyback Converter.

What is a DIN rail used for?

A DIN Rail is used to mount electrical components in an electrical cabinet, rack, or wall.

What is a DIN rail circuit breaker?

They are miniature circuit breakers designed to mount to a DIN Rail to protect low-power equipment from short circuits and current overloads.

What is a 24V DC power supply?

A 24V DC power supply can transform AC to DC while simultaneously adjusting the voltage level.

How do DIN rail terminal blocks work?

They are small “connector” pieces used to connect wires within a DIN rail-mounted system safely.

How much weight can a DIN rail hold?

DIN Rails can hold components of up to 1.1 lbs in weight.

What size is DIN rail?

The DIN EN 60715 is the standard DIN Rail, and it is 35mm (W) x 7.5mm (H).

How do I connect DIN rail terminal blocks?

DIN Rail terminal blocks are snapped onto the DIN Rail directly.

What are the types of DC power supply?

Batteries and solar devices are the primary sources of DC power.

What are the components of a power supply?

A power supply contains the following components: transformer, rectifier, filter, and regulator circuits.

What is the main function of SMPS?

The main function of SMPS (switched-mode power supply) is to obtain a controlled dc power supply by converting power with switching devices that turn on and off at high frequencies.

Why do we use SMPS?

An SMPS is used to convert the supply voltage to the desired voltage of the particular electronic device.

What's the difference between SPS and UPS?

SPS is a Standby Power Supply, and UPS is an Uninterrupted Power Supply. An SPS contains a battery like the UPS, but the battery only provides power to the device when it loses AC power - whereas the UPS provides uninterrupted power.

What is a DIN rail relay?

DIN Rail Relays are electrical switches that turn devices on or off and help keep equipment running smoothly.

What are two DC supply types?

The two major types of DC power supplies are regulated power supplies and unregulated power supplies.

What are the types of DC voltage usually produced by a power supply?

There are four primary outputs or DC Voltage types: constant voltage, constant current, voltage limit, and current limit.

What uses a 12V DC power supply?

A 12V power supply, like a 12V battery, is commonly used in RV, boat, and other automobile systems.

What are industrial relays?

Industrial Relays are electrically operated switches that use electromagnetism to allow a lower voltage circuit to operate a higher voltage circuit.

Why are relays used in industry?

In addition to reducing the current that flows through the primary control switch, Industrial relays can protect electronic equipment by detecting overcurrent, overload, undercurrent, and reverse current.

Why use a relay instead of a switch?

A Relay can switch many contacts at once, which is more convenient and safer in an emergency because it is one switch vs. many.

What is the difference between a contactor and a relay?

Contactors and Relays are both electromagnetic switches; however, a relay can carry loads of 10A or less, while a contactor can carry loads greater than 10A.

Is there any difference between AC and DC fuse?

Yes, the DC fuse is continuous, but the AC fuse goes to 0 volts with each cycle; therefore, it is harder to stop the arc that forms if the DC fuse blows.

What are industrial fuses made of?

Industrial Fuses include a low resistance metallic wire enclosed in a non-combustible material.

What are the different types of disconnect switches?

The two main types of disconnect switches include battery disconnect switches and electrical disconnect switches.

When should you use a disconnect switch?

Use a Disconnect Switch to safely terminate an electrical circuit before service or maintenance.

What are DC contactors used for?

DC Contactors reliably switch currents on low voltage DC settings and are commonly used in electric power, distribution, and electricity applications.

What is the difference between AC and DC contactor?

AC and DC contactors have several differences. An AC contactor has an E-shaped electromagnetic core of laminated silicon sheets, a short circuit ring to eliminate vibration and noise, a starting current of 600 times/hour, and a quenching grid arc. A DC contactor has a U-shaped soft steel electromagnetic core, no short circuit ring, a 1200 times/hour starting current, and a quenching magnetic arc.
