Deze programmeerbare counters:

Komen uit een werkende opstelling, maar liggen al een jaar in de doos....

Ideaal als je een wikkelbankje wil maken om de slagen te tellen. Je kan de machine dan automatisch laten afslaan bij een vooraf ingesteld nummer omwentelingen.

SPECIFICATIONS

I. Power Requirements

120VAC +10% - -20% 50/60 Hertz. Power is connected to the rear panel terminals provided, including chassis ground.
The power circuit is connected directly to the input power transformer primary without power switch or fusing.
Nominal wattage for a 4 digit unit is 6 watts with display, 5 watts without display. Maximum current is 0.1 amp with display, 0.08 without display.

II. Counter and Coincidence

A. Number of digits: 2, 3 or 4.
B. Coincidence selection: Bi-directional switches.
C. Characteristics:
Turn on to all zeros. (Higher order zeros blanked.)
Reset must override count.
Coincidence with count input only.
Display of power "ON" by LED indicator and change in the LED
light intensity as manual contact closure count inputs are made.
D. Counter reset functions:
Front panel switch (depression of a momentary toggle switch).
External contact (circuit) closure to power supply common.
Automatic recycle with coincidence. (Jumper recycle terminal to
+15VDC.)

Maximum immunity to reset contact bounce, contact noise or
external electrical noise (Schmitt Trigger reset input).
When reset switches are used to terminate the relay actuation
output, the output is to terminate with the release of the switch
(latch until reset is completed).

III. Output Control

A. Two form "C" contacts rated 10 amperes resistive at 120VAC or 28VDC.
B. Output relay functions selectable at rear terminals. Timed 100 milliseconds (jumper time out terminal and+15VDC)
variable to 10 seconds (with external resistance added between time out terminal and +15VDC).

Latch until reset is completed (jumper LURC terminal to +15VDC). Latch until external contact or circuit closure (unlatch terminal jumpered to common). This circuit has a Schmitt Trigger input.

C. Count output is provided to operate a second Series 1000 control or other logic circuit. This output assures compatibility of any other unit even with variations in production and short on or off time for the count input. Count Inputs (Always connect count input between input terminal and common.)

A. Count circuit input to 5 kilohertz. Includes operation for most all
Durant transducers which are not better suited to slower count speed
of "B".

B. Count contact closure to 150 hertz. To be used in all Possible
Applications and includes operation for ES9513-RS, reed switch
49485-400, as well as slow speed encoder application, etc. (Count
input is connected as indicated above and the "Low Frequency"
terminal must be jumpered to common.)

C. Count invert. The count is entered when the contact is opened, the
photocell goes dark, etc. (Connection is to be made between the
"invert" terminal and common. Count input must be made per IV.

D. Provide 15VDC (plug and two commons) at rear terminal for
Durant transducer operation. To be rated for 100 milliampere output
at 15V +0.5, -2.0 VDC full line and load regulation.

V. Rear Panel Terminals

A. Six terminals for form "C" relay output contacts.
B. Output/input terminals.

1. Count input invert (jumper invert terminal to common).
2. 15VDC common.
3. Slow speed count (jumper low frequency terminal to common).
4. Count output (connect additional control count input terminal to this count output and jumper commons of both units).
5. Count input (for both slow and high speed counting, connect count input between count input terminal and common).
6. 15VDC positive (added terminal to facilitate wiring).
7. 15VDC common (added terminal to facilitate wiring).
8.
9. Timed output (jumper time out terminal to +15VDC for 100 milliseconds or add resistor in lieu of jumper, for time out up to 10 seconds).
10. Latch until reset is complete (jumper LURCterminal to+15VDC).
11. Auto recycle (jumper auto reset terminal to +15VDC).
15. Latch until external contact closure or circuit is made (connect switch or circuit between unlatch terminal and common).
17. Counter reset (connect remote reset switch between reset terminal and common).

VI. Displays

A. .300 inch LED count display.
B. Optional decimal point of LED count display optionally availab
C. Power "ON" and counting LED indicator. In this case an LED
lite is to operate with power "ON" and to reduce in intensity
count input so that counting is visually apparent at low speed m;
count contact closures.
D. Ripple blanking of higher order zeros.
