Rơ le hẹn giờ là gì?

A timer relay changes one or more output contacts according to a defined time function after a control or supply signal is applied or removed.

Selection requires the timing function, adjustable range, supply voltage, trigger method, contact arrangement and load duty, reset behavior, accuracy, repeatability, mounting and environmental conditions.

Trigger receivedThe timer detects the configured supply or control input.
Timing sequence runsThe selected function measures the adjusted interval.
Output changes stateRelay contacts operate according to the timing diagram.

How to choose a timer relay

Define the timing diagram first, then match range, supply, trigger and output contacts.

Thời gian chức năng và nhiều

Select on-delay, off-delay, interval, cyclic or another published function and suitable adjustment range.

Supply and trigger

Match AC or DC control voltage, frequency and separate trigger requirements.

Output contacts and load

Confirm contact arrangement, switching duty and any interposing device required for the load.

Reset, accuracy and mounting

Check reset time, repeatability, indicators, DIN-rail or panel format and environment.

Draw the timing diagram before selecting the relay

Input state, delay, output state and reset behavior must match the machine sequence.

Các câu hỏi lựa chọn Rơ-le thời gian

Câu trả lời nhanh để so sánh sơ bộ các dòng sản phẩm trước khi xác minh chi tiết mạch điện.

Which timer function should be selected?

Use the required input, delay, output and reset sequence; compare the exact timing diagram for the model.

How is the time range chosen?

Choose a range that contains the required delay with useful adjustment resolution and verified accuracy.

Why does supply voltage matter?

The timer electronics and relay coil must match the actual control supply and frequency.

Can timer contacts switch a motor directly?

Only when the exact contact rating and utilization duty permit it; many loads require an interposing contactor or relay.

What is the difference between multifunction and single-function timers?

A multifunction timer offers selectable timing modes, while a single-function model is dedicated to one sequence; compare complexity, setting security and application needs.
