Reliable timing relays for plant and building automation
Timing relays play an important role in many areas of plant and building automation. They are always used when switch-on or switch-off processes are to be delayed or when short pulses are to be extended. They are used, for example, to avoid errors during short switching cycles that cannot be reliably detected by downstream control components. Timing relays are also a simple way of integrating timer functions into a system without PLC, or implementing them without programming effort. The Klippon® Relay portfolio provides you with relays for various timing functions such as on-delay, off delay, clock generator and star-delta relays. We also offer timing relays for universal applications in factory and building automation as well as multifunction timing relays with several timer functions. Our timing relays are available as a classic building automation design, a compact 6.4 mm version and with wide-range multi-voltage input. Our timing relays have the current approvals according to DNVGL, and cULus and can therefore be used internationally.
Compact timing relays for building and factory automation
Our TFI-SERIES consists of different devices covering the most important applications in building and factory automation. Four of these carry out individual functions: clock generator (pause and pulse start), star-delta switch, switch-on delay and off-delay with control input. There is also a multifunctional version with seven different timing functions. The timing functions and time ranges can be easily configured using a rotary switch fitted on the front. All of the devices meet the international standards according to EN 61812.
Available in installation design and compact industrial design
Simple configuration via setting potentiometers and status LED
Compliance with international standards according to EN 61812
Timing relay for control signal adaptation with additional functions
Timing relays are used to coordinate fast switching processes in control systems, among other things. TERMSERIES TIMER timing relays have a on-delay, which allows for the delayed switch-on of machines, the cascaded start-up of system components or the delayed activation of consumers such as pumps or valves. They also have the One Shot and blinker functions. TERMSERIES TIMER timing relays in compact 6.4 mm terminal block format are available with either a screw connection or a PUSH IN wire connection. The timing functions and time ranges can be conveniently adjusted via the DIP switches on the side. The power supply and the respective switching status can be checked at a glance by means of the clearly visible duo LED on the ejection lever. International approvals in accordance with EN 61812 mean that they can be used anywhere in the world. TERMSERIES TIMER is compatible with the wide range of TERMSERIES accessories, thereby ensuring high levels of flexibility and simple integration into existing systems.

Compact multi-functional timing relay for easy control signal adjustment
With IT-TIMER, Weidmüller‘s range includes a highly efficient timing relay with multi-voltage input that combines a range of functions with a compact size. It is particularly easy to configure the timer functions thanks to the flat front cover, the easy-to-read LED status indicator and operation with standard tools. IT-TIMER meets the requirements of IEC 618121. It is designed for an operating voltage range from 24 V DC to 48 V DC or 24 V AC to 240 V AC and can therefore be used in a wide variety of applications.

Timing functions that are easy to configure using standard tools
Can be used internationally thanks to compliance with EN 618121
Seven timing functions for a wide range of applications make the IT-TIMER a smart solution for your application
The narrow pulse stretcher measuring just 6.1 mm wide
Pulse stretchers are used in automation technology to extend very short input pulses of less than 10 ms. Such short pulses are generated by light barriers, for example, and cannot be processed by conventional timing relays. The extended pulses, on the other hand, can be forwarded directly to the PLC. MCZ TO is one of the narrowest pulse stretchers on the market. It extends even very short pulses ? 3.5 ms and has a fixed switch-off delay (50 ms or 150 ms). MCZ TO operates with low input power, and auxiliary voltages in the input and output are not required. It also includes a watchdog function with restarting of the off-delay. Precisely fitting accessories such as cross-connectors, markers and end plates make it flexible to use.
Detection of very short input pulses (? 3.5 ms)
Versatile to use thanks to three cross-connector connections
Proven and reliable tension clamp connection system
High level of safety thanks to integrated reverse polarity protection
