Product description

What is a timer?

 

A timer is a simple automation component which is used to manage actions over a period

of time or control how long actions last.The timer is a control device which triggers an

action according to a time and a function. After a predefined time has elapsed, the timer

closes or opens one or more contacts.

 

Timing cycles, whether single shot or repetitive, are started by latching inputs or pulsed inputs,

allowing a wide variety of functions to be created.

 

To execute which actions?

 

A timer can be used to trigger an action according to a predefined time. It can also be used to stagger actions over a period of time.

 

In any time-related application, the timer can play a role and can be

used to:

 

• Run installations according to times that can be adjusted by the user.

• Calibrate a machine running time.

• Allow or prevent an action.

• Delay an action.

• Manage stopping/starting of a motor, pump, etc. (star delta).

• Make an LED flash.

 

Crouzet timer features;

 

  • Available in mono- or multifunction  versions (analogue or digital, with or without latching), to meet the specific needs of each application.
  • A timing range of up to 9,999 hrs to cope with prolonged processing operations.
  • A range of power supplies from 12 to 240 V in one unit for optimised stocks.
  • Recognised quality and reliability ensures the correct operation of equipment.
