DIN Rail Timers for Industrial Timing and Control
ATC Diversified Electronics offers a versatile range of DIN rail timers and time delay relays designed for industrial automation, machine control, motor and pump systems, material handling, and other applications requiring dependable timed switching.
Available configurations include multifunction timers, ON-delay timers, true off-delay timers, repeat-cycle timers, asymmetric flasher relays, inhibit-delay timers, and programmable 7-day timers. This range allows engineers and control-panel designers to select a timing function that matches the sequence, delay, cycle, or scheduling requirements of the application.
Selected ATC DIN rail timers provide universal 12-240 VAC/DC or 20-240 VAC/DC supply capability, multiple timing ranges, front-panel adjustment, status indication, and slim housings designed to conserve control-panel space. Available products range from dedicated single-function timers to multifunction devices offering numerous timing modes in one unit.
Why Choose ATC DIN Rail Timers?
Multiple Timing Functions: Choose from ON-delay, off-delay, interval, repeat-cycle, asymmetric flashing, inhibited timing, daily and weekly scheduling, and other timing functions depending on the selected model.
Wide Timing Ranges: ATC DIN rail timer families cover applications requiring timing from fractions of a second through minutes, hours, days, and scheduled weekly operation.
Universal-Voltage Options: Selected models support wide AC/DC supply ranges, helping reduce the number of timer variants required across different control-panel applications.
Space-Saving DIN Rail Mounting: Slim DIN rail housings allow timers to be installed efficiently alongside relays, power supplies, motor controls, and other components inside industrial control panels.
Simple Configuration: Depending on the model, timing functions and ranges can be configured using rotary switches, adjustment knobs, potentiometers, keypads, or digital displays.
Industrial Control Applications: ATC DIN rail timers are used in OEM equipment, packaging machinery, plastics equipment, conveyor systems, material handling, motor and pump control, and process-industry applications.
Multifunction, Delay and Repeat-Cycle Timing Options
For applications requiring multiple timing modes in one device, the 175MD, 175MU, DTA100USD, and DTB100USD provide multifunction timing capabilities. The 175MD offers 15 functions and eight timing ranges, while the 175MU provides 13 functions and 10 timing ranges. The DTA100USD and DTB100USD each provide 10 timing functions, with the DTB100USD adding an inhibit input that can pause a timing sequence.
For dedicated applications, the 175SO-110 provides single-function ON-delay control, while the DTT100USD provides true off-delay timing. The DTF100USD provides independently adjustable ON and OFF periods for asymmetric flashing and repeat-cycle applications.
Applications requiring scheduled operation can use the 7DT-2CH Series 7 Day Timer, which provides daily and weekly programming with two independent control channels and a clear LCD display.
Find the Right DIN Rail Timer
Selecting the right DIN rail timer or time delay relay depends on the required timing function, timing range, supply voltage, contact rating, number of outputs, control inputs, panel space, and whether the application requires simple delay timing, repeat cycling, true off-delay operation, or programmed daily and weekly scheduling.
Explore the ATC DIN rail timers above to compare available timing functions, ranges, voltage options, outputs, and control features. ATC Diversified Electronics can also assist with selecting a timer for OEM equipment, industrial automation, motor control, and control-panel applications.
DIN Rail Timer FAQs
What is a DIN rail timer?
A DIN rail timer is an industrial timing device designed to mount directly on a standard DIN rail inside an electrical control panel. It controls relay outputs according to a selected time delay, timing sequence, repeat cycle, or programmed schedule.
What is a time delay relay?
A time delay relay changes the state of its output contacts according to a defined timing function. Depending on the model, the output may switch after power is applied, remain energized after power is removed, cycle repeatedly, or operate according to another programmed timing sequence.
What timing functions are available in ATC DIN rail timers?
ATC offers DIN rail products with functions including ON-delay, true off-delay, multifunction timing, inhibit delay, repeat-cycle timing, asymmetric flashing, and daily or weekly scheduling. Available functions vary by model.
What is a multifunction DIN rail timer?
A multifunction DIN rail timer combines several timing modes in one device. For example, the ATC 175MD provides 15 timing functions and eight timing ranges, while the 175MU provides 13 functions and 10 timing ranges.
What is an ON-delay timer?
An ON-delay timer begins timing when its control or supply signal is applied. After the selected delay expires, the output relay changes state. The ATC 175SO-110 is a dedicated DIN rail ON-delay timer with 10 selectable ranges from 0.1 second to 3 hours.
What is a true off-delay timer?
A true off-delay timer begins its timing period when input power is removed and keeps the output in its controlled state for the selected delay period. The ATC DTT100USD provides adjustable true off-delay timing from 0.1 second to 10 minutes.
What is a repeat-cycle or asymmetric flasher timer?
A repeat-cycle timer repeatedly switches its output ON and OFF. An asymmetric repeat-cycle timer allows the ON duration and OFF duration to be adjusted independently. The ATC DTF100USD supports independently adjustable timing from 0.1 second to 100 days.
What does inhibit delay mean on a timer?
An inhibit input allows an active timing sequence to be paused or controlled by an external signal. The ATC DTB100USD includes inhibit-delay capability along with 10 timing functions and three discrete relay outputs.
Does ATC offer a programmable weekly DIN rail timer?
Yes. The ATC 7DT-2CH Series provides daily and weekly programming with two independent control channels. It includes an LCD display, manual or automatic switching, and a minimum programmable interval of one second.
Do ATC DIN rail timers support universal supply voltage?
Selected models do. For example, the DTA100USD, DTB100USD, DTF100USD, and DTT100USD support 12-240 VAC/DC supply voltage. The 175MD supports 20-240 VAC and 20-240 VDC. Other products use different supply specifications, so the individual timer specifications should be checked.
What applications use DIN rail timers?
DIN rail timers are commonly used in OEM equipment, packaging machinery, plastics machinery, conveyor systems, material handling, industrial equipment control, motor and pump systems, and process-industry control panels.
How do I choose the right DIN rail timer?
Consider the required timing function, minimum and maximum timing range, supply voltage, output contact rating, number of relay outputs, control inputs, available panel space, and whether the process requires a simple delay, multifunction timing, repeat cycling, true off-delay operation, or scheduled daily and weekly control.
