Operating principle

A timer is an automation control component which is designed toenergise an output contact during a precise timing cycle.It is also known as a “time delay relay”, “specified-time digital relay”or even an “electronic timer”.

The timing cycle starts when either power is applied to the timer or with an initiate switch. The timer model determines whether an initiateswitch is required. The delay on make time function in a Chronos 2will begin as soon as the power is applied. With the 88 857 series(TOP 948), an initiate switch is required.

Initiate switches can also be either a maintained or impulse (momentary)type contact.

Because of these options, there are a large number of potential timingfunctions and products.



Operating principle

There are 4 types of timers are available:

“DIN-rail mounted” products designed to be mounted to a standard 35 mm DIN-rail inside a wall-mounted or floor-standing enclosure.

“Panel mounted” products designed to be mounted on the front of a control panel for easy access by the user.

“Plug-in” products designed to be used with an industry standard8 or 11 pin socket. The socket can mount on a DIN-rail or surfacein an enclosure.

“Surface mounted” products designed to be mounted to a surface inside a enclosure.



Operating principle

Timing functions require a time reference to ensure the accuracy ofproducts.This time reference is known as the “time base”

The time base is obtained using one of two technologies:

- Electromechanical: The time base is obtained from a synchronousmicromotor whose speed depends solely on the frequency of themain supply on which it is connected.This motor, associated with a gearbox, controls contacts, usuallymicroswitches.

- Electronic: Several techniques are used: analogue or digital(counting) to obtain the time base.The output component is usually an electromechanical relay.Solid-state outputs are also possible.

Applications

General

Timer controls can be used in addition to a programmable controller (or PLC) or in places where a programmable controller is not necessary. The requirement can be as small as one input and one output. Two outputs are also available on some products.

Combinations can also be used for more complex functions.

Cam timers


Products

The competition



Operating principle

A CAM TIMER is an automation control component designed to actuatea series of contacts in a predetermined order during a cycle,according to a cyclical program.

The cycle can be: single-shot, repetitive, or step-by-step.

Often underrated, cam timers can be used to simplify automationsystems considerably and eliminate the need for manycomponents.



Operating principle

Cam timers consist of:

- A drive device: synchronous geared motor

- Data carriers: standard, adjustable (programmable), or precut striker cams

- Output switching components: microswitch (electrical) or microvalve (pneumatic)

Standard Programmable Custom


Adapted products

There are numerous possibilities when creating camtimers.- Switching possible with 1 to 40 circuits- Possibility of complex cycles with 2 motors- Assembly of microswitches and microvalves- Etc
