There are many different types of timer relays to suit a wide variety of applications, lets take a closer look at the main versions:

DIN Rail Timer Relays

DIN rail-mounted timer relays offer compact and accurate solutions with on-delay operation and various timing ranges up to 60 minutes

Dold timer relays, available in the most popular timing functions, offer selectable time ranges from 0.02 sec to 300 hours and are DIN-rail mountable.

Panel Mounted Timers

1/16 DIN Solid State Multifunction Timer is a cost-effective product with excellent application flexibility, offering 4 operating modes and sixteen time ranges selectable from the front panel.

Multi-Function Timers

A multi-function timer is a device that can perform various timing functions simultaneously or sequentially such as automatic door openings, lighting in toilets and car park barriers.

Modes of Operation

Timer relays offer several modes of operation, including on-delay, off-delay, on-delay flasher, on-interval, single shot, and cyclic (repeat cycle). These modes allow for precise control of processes and machine tools based on user-specified time intervals.

Applications

Timer relays are indispensable across various applications, including Process Control, Machine Tool Control, Safety Control, Immersion Heater Time Controllers.

Immersion Heater Timer Controllers

Timer relays are extensively used as immersion heater timer controllers to precisely control the heating cycles of immersion heaters. These devices enable users to set specific time intervals for the operation of immersion heaters, ensuring optimal heating efficiency and energy conservation.

Industrial Timers

In industrial settings, timer relays find applications in controlling the operation of various industrial equipment and processes. They offer precise timing control, enabling efficient and reliable operation across diverse industrial applications.

Programmable Timers

The programmable ability of timer relays allows for customisation of timing intervals based on specific industrial or commercial requirements. This flexibility makes them an ideal choice for applications where precise timing control is critical.
