DAYTON 5DRA3 Multi Function Time Delay Relay, Socket Mounted, 24V AC/DC, 10A, 11 Pins

Dayton 5DRA3 timer relay in industrial and automation processes to control timing sequences in machinery, lighting systems and automated systems. This relay offers precision timing, enabling synchronised operations, cycle control and delayed functions. It enhances efficiency by automating processes, reducing manual intervention and optimising resource utilisation. This timer relay can be adjusted using push button and a rotary knob for easy handling and operations.

Working Mechanism:

• Apply an electrical input signal to Dayton DRA3 timer relay.
• The relay starts its timing cycle upon receiving the input signal.
• The internal timer mechanism counts the set time duration.
• When the set time elapses, the relay's contacts transition.
• The transition of contacts activates or deactivates connected devices or circuits.
• The connected devices or circuits undergo the desired action based on the timing sequence.
• Depending on the relay type, the timing mechanism may reset automatically or manually.
• The relay can repeat the timing cycle for continuous or periodic operations.
• When the input signal is removed, the relay resets for the next cycle.
• The relay is ready to start another timing cycle upon receiving a new input signal.

Features:

• Dayton 5DRA3 multi-function timer delay relay uses a pushbutton thumb wheel and a rotary knob to accomplish programming by selecting one of the seven built-in time ranges & one of the ten built-in functions, and digitally set the time delay required.
• It comes with an LED to indicate the time-out-condition and timing mode.
• This 24V timer relay allows plug-in mounting and has an octal base for quick installation.
• It offers a DPDT terminal connection and an analogue meter to display mode & timing delay.
• It features silver nickel contacts for hardness and corrosion resistance.

Compatible Accessories:

• Dayton Relay Sockets: 5DRA3 timer relay can be fitted with these relay sockets (1EGP2, 1EGP4 & 6X156). They provide electrical interfacing between the circuit and the relay.

Standards and Approvals:

• CE
• CSA
• UR

Q. How do I choose the correct timer relay for my needs?

A.

• Determine the required timing functions (delay, pulse, cycle).
• Choose a relay with a suitable time range for your application.
• Ensure the relay can handle your load's current and voltage.
• Select the appropriate mounting style (panel, socket, DIN rail).
• Choose the relay with the required number of contacts.
• Ensure the relay is compatible with your input voltage.

Q. What factors should I consider while choosing a timer relay?

A.

• Choose a timer relay that suits your required delay or timing function.
• Ensure compatibility with your system's voltage level.
• Select a relay with a time range that covers your desired delay interval.
• Determine if you need a normally open (NO) or normally closed (NC) contact.
• Choose a relay that fits your installation setup, like panel mount or DIN rail.
• Make sure the relay's contacts can handle the current and voltage of your application.
• Consider features like reset options, LED indicators and adjustable settings.
