Timing Devices From DOLD

Timers hardware belongs to the earliest subject areas DOLD has devoted to. Already many decades ago, DOLD set completely new standards with the development of compact and versatile timing contactors. Soon after this, DOLD timing relays made their arrival in a variety of time-dependent controls in industries and building services engineering. The MINITIMER and MULTITIMER brands became a synonym for precision and reliability in timing control. Today, with their complete range of electronic, electro-mechanical and electro-pneumatic timing relays DOLD offers also many customer-specific solutions for timing control problems apart from mono- and multifunctional standard products.

Advantages

  • A timing relay is a special relay variant which can be used to realize specific timing functions in a cost-effective manner
  • Electronic timing relays with semiconductor outputs for frequent wearless switching
  • Easy and cost-effective stockkeeping because of only a single device for many applications (multifunctional relays)
  • Save space by narrow design
  • Elapsed time indication for electromechanical timing relays
  • Non-resetting on voltage failure designs for electromechanical timing relays
  • Safe timer relay for the most demanding applications

Technology

Timer relays (relays with a defined timing function) are used in industry or building automation to achieve economic on or off delayed time functions. Electromechanical timers are normally syncronous motor driven, electro-pneumatic timers have a neumatic time arrangement and modern electronic timers a re controlled by microprocessors. Electronic timers incorporate conventionel relay contacts or semiconductor outputs.

Functions

  • Delay on operate: Initiation is by applying the operating voltage. Once the set delay time has lapsed the relay switches to its operated condition.
  • Release delay: When the operating voltage is applied the relay immediately switches to its operated condition. When the operating voltage is interrupted, the release delay time starts. Once the set delay time has lapsed the relay switches to its normal position.
  • There is a differentiation between devices without and such with auxiliary voltage.
  • Devices without auxiliary voltage can only control short times (up to 5 minutes), devices with auxiliary voltage are also suited for longer times because their delay function is initiated by triggering the control input. These products are also suited for applications with very short operating times.
  • Flasher timers: When the operating voltage is applied the relay switches to its operated condition (on the lead edge of the pulse). Once the pulse time has lapsed the relay switches to its normal position. After the end of the dead time it returns to its operated condition and so on (pulse time = dead time).
  • Cyclic timers: Same functions as the flasher timer, but pulse time and dead time are different and therefore they can be separately adjusted.
  • Fleeting action: A fleeting action NO relay switches to its operated condition without delay when the operating voltage is applied. Once the set fleeting time has lapsed the relay switches to its normal position. A fleeting action NC relay has voltage applied to the control input via the control contact. When the control contact is opened the relay immediately switches to its operated condition. Once the set fleeting time has lapsed the relay switches to its normal position.
  • Pulse shapers: Convert the input pulse to an output pulse with a defined length (set time).
  • Multifunction relays: These devices can be used for each one of the above functions. Needed functions can be adjusted on the device.
  • Star delta timers: The star contact is closed when the operating voltage is applied. Once the set fleeting time has lapsed the star contact opens and after a short dead time (contact transit time 35 to 100 ms) the delta contact closes.

For MK9906N, MK 9962N , MK 7854N , MK 7850N and IK/SK 9906 , IK/SK 9962 , IK/SK 7854 , IK/SK 7854 :

  • Voltage range AC/DC 12-240 V
  • 8 time ranges from 0.05 s - 300 h
  • Setting aid for quick setting of long times
  • LEDs for ready-for-operation, contact position, time sequence
  • Optionally with timing interruption/time addition and with connection to a remote potentiometer
  • Optionally 1 changeover contact programmable as instantaneous contact (for MK....N models)

Applications

  • Delay on operate: Lead timing circuits (e.g. preheating); delay times in control systems: delayed starting of plant components, e.g. starting of slipringmotors (switching starting resistors), burner controls, escalators, elevators
  • Release delay: After-run timing, e.g. fans, lighting controls, staircase lighting, minute lighting, delayed switching to emergency generating set/lighting
    Without auxiliary voltage: used for release times <5 minutes
    With auxiliary voltage: used for release times > 5 minutes and for very short operating times
  • Flasher timers: trigger fault indicators or navigation lights: flashing lights on cranes, wind parks, airport lighting systems
  • Cyclic timers: e.g. traffic light controls, automatic baking machines
  • Fleeting action timers: dosing systems, washing facilities
  • Pulse shapers: e.g. switch cabinet: setting the length of different signals
  • Multifunction relays: versatile by function selection
  • Star delta timers: e.g. automatic motor starting control

Special applications:

  • Multifunction Safety Timers UG 6960 and UG 6961 the SAFEMASTER C family: Can be used for applications up to Performance Level (PL) e and Category 4 according to EN ISO 13849-1: 2008, SIL claimed level (SIL CL) 3 according to IEC/EN 62061, Safety Integrity Level (SIL) 3 to IEC/EN 61508 and also for safety relevant systems in process industry IEC/EN 61511.
