Totalising counters

Predetermining counters

Totalising timers

These are used for counting events from electrical pulses or contacts. The

value is displayed and updated in increments on each new pulse.

Application : counting the number of parts

In automatic mode : the totalising counter performs this operation in

conjunction with a photo-electric detector, inductive sensor or limit switch, which

detects the passing of a part and translates this by adding one unit to the number

of parts counted by the totalising counter.

In manual mode : the totalising counters performs this operation in conjunction

with a pushbutton. A press on the button adds one more unit to the value

displayed. This system can be used with a ticket distributor or a manual

assembly station.

These are used for counting events from electrical pulses or contacts. The

value is displayed and updated in increments or decrements on each new

pulse.

They can be used to enter a preset value manually. When this predefined

value is reached, they send an electrical signal. Predetermining counters can

be adding or subtracting.

Applications : upcounting or downcounting the number of parts.

The predetermining counter counts the number of parts in the same way as a

totaliser. When the selected value is reached, the preset counter, in

conjunction with the various sensors, sends a signal to trigger actions, such as

stopping a machine or conveyor belt.

These are used to count and display the time, with a precision of a hundredth

of an hour.

Applications : they can be used to measure the duration of an action or of the

use of a machine.
