Weekly Timers
Weekly Timers for Programmable Daily and Weekly Control
ATC Diversified Electronics offers the 7DT-2CH Series 7 Day Timer for applications that require programmable daily or weekly switching. Designed for DIN rail mounting, the timer provides two independent control channels so equipment, circuits, or processes can operate according to separate schedules from a single device.
A clear LCD display provides visible indication of the current day, time, operating mode, and output status. Programming is handled through four front keys, with a minimum switching interval of one second for applications that require precise scheduled control.
The 7DT-2CH supports both automatic programmed operation and manual switching, while automatic summer and winter time conversion helps simplify seasonal clock changes. With two independent outputs and 16 A contacts, it provides a compact weekly timing solution for industrial control panels, OEM equipment, building systems, pumps, lighting, machinery, and other scheduled electrical loads.
Why Choose the ATC 7 Day Timer?
Daily and Weekly Programming: Create recurring schedules based on specific days and times within a seven-day operating cycle.
Two Independent Control Channels: The 7DT-2CH provides two separately controlled outputs, allowing one timer to manage two independent circuits or scheduled functions.
One-Second Minimum Interval: Programming intervals can be set as short as one second for applications requiring more precise scheduled switching.
Clear LCD Display: The front display shows output status, operating mode, day, and time to help simplify programming and monitoring.
Automatic or Manual Operation: Outputs can operate according to the programmed schedule or be switched manually when temporary control is needed.
Automatic Seasonal Time Adjustment: Built-in summer and winter time conversion helps reduce manual clock adjustments when seasonal time changes occur.
DIN Rail Mounting: The compact DIN rail design allows convenient installation alongside relays, power supplies, motor controls, and other industrial control-panel components.
Weekly Timer Applications
Programmable weekly timers are useful when electrical equipment must operate automatically according to recurring schedules. Applications can include lighting, pumps, fans, heaters, process equipment, building systems, machinery, irrigation equipment, and other electrical loads that need to turn on or off at specific times or on selected days of the week.
Find the Right Weekly Timer
Selecting a weekly programmable timer requires consideration of the required number of output channels, contact rating, minimum switching interval, programming flexibility, mounting method, manual-override needs, and the operating schedule of the connected equipment.

Weekly Timer FAQs
What is a weekly timer?
A weekly timer is a programmable electrical control that switches one or more outputs according to scheduled times and days of the week. It allows equipment to operate automatically according to a recurring seven-day schedule.
What is the ATC 7DT-2CH Series 7 Day Timer?
The ATC 7DT-2CH is a DIN rail-mounted programmable timer designed for daily and weekly scheduling. It provides two independent control channels, an LCD display, manual and automatic switching, and programmable intervals as short as one second.
Can the 7DT-2CH control two different circuits?
Yes. The 7DT-2CH provides two independent channels of control, allowing separate circuits or electrical loads to operate according to different programmed schedules.
Can the ATC weekly timer be programmed for different days?
Yes. The 7DT-2CH supports both daily and weekly programming so switching events can be scheduled according to specific days and times within the seven-day cycle.
What is the minimum programmable interval on the 7DT-2CH?
The minimum programmable interval is one second, allowing the timer to support both longer daily schedules and applications requiring short scheduled switching periods.
Does the 7DT-2CH have a manual override?
Yes. The timer supports programmed automatic switching as well as manual operation, allowing the output state to be changed when temporary control outside the normal schedule is required.
What information does the LCD display show?
The 7DT-2CH LCD provides visible indication of output status, operating mode, day, and current time to assist with programming and operation.
Does the ATC 7 Day Timer adjust for seasonal time changes?
Yes. The 7DT-2CH includes automatic summer and winter time conversion, helping reduce the need for manual clock adjustments when seasonal time changes occur.
What is the contact rating of the 7DT-2CH?
The ATC 7DT-2CH is specified with 16 A contacts. The connected load and electrical system should always be checked against the complete timer specifications before installation.
How is the ATC weekly timer mounted?
The 7DT-2CH is designed for DIN rail mounting, allowing it to be installed inside industrial electrical and automation control panels alongside other DIN rail components.
What applications use weekly timers?
Weekly timers can be used for lighting, pumps, fans, heaters, process equipment, building systems, machinery, irrigation controls, and other electrical loads that need to operate automatically according to recurring daily or weekly schedules.
What is the difference between a weekly timer and a time delay relay?
A weekly timer switches outputs according to calendar-based days and times. A time delay relay typically performs a delay or timing function after an electrical control event occurs, such as applying or removing power.
