Time Delay Relays

Time Delay Relays are electromechanical devices designed to delay certain actions for a predetermined length of time. The time delay may be adjustable or fixed depending on the specific application. Commonly used in industrial automation, HVAC, and automotive applications, Time Delay Relays provide an element of flexibility required in control systems.

H3JA-8A AC200-240 30S Time Delay Relay

The H3JA-8A AC200-240 30S Time Delay Relay is a versatile and reliable option for many applications. It features a timer-cyclic time-limit, can switch on/off cycle-by-cycle, and can achieve adjustment of contact action and time setting by means of pointer in both directions. This Time Delay Relay is capable of carrying a rated current of 250V AC 2A, with a rated voltage of 200-240VAC.

Application Field

The H3JA-8A AC200-240 30S Time Delay Relay is suitable for controlling the starting and stopping of actuating mechanisms in motors, pumps, ventilation fans, and other industrial equipment. It can also be used to turn on/off electric illumination, heating, cooling, and other electrical equipment in household and commercial applications.

Working Principle

The H3JA-8A AC200-240 30S Time Delay Relay consists of a time-delay relay, a timing range adjustment device, a time-delay contact block and a time-delay indicator. When the main control circuit is in the "ON" position, the input voltage will power supply the time-delay relay, enabling the internal circuit. When the time delay is reached, the output contact will switch states, turning either on or off and thus allowing the associated circuitry to be used.

The time delay can be adjusted by turning the timer knob or adjusting the terminal screws. The time delay can range from 0 to 30s. When the adjustable time delay exceeds the set time, the contact block is changed and outputs the corresponding control signal. This signal can then be used to control the turning on or turning off of the associated mechanical or electrical equipment.

The H3JA-8A AC200-240 30S Time Delay Relay provides reliable, integral timing capability that can be easily integrated into existing control systems. The 0-30s time delay range combined with adjustable timing options makes it suitable for many applications.
