IEEE SYSTEMS FOR PRODUCTION AND TEST AUTOMATION

ALSO FORCE/DISPLACMENT TESTING SYSTEMS FOR KEYBOARDS

AND MECHNICAL ASSEMBLIES 0-1N, 0-10N, 0-500N


 
The A8274 KWP Force Displacement Test System, certified according to DIN ISO 9001, has been designed to measure the force vs. displacement characteristic.
Possible modes of operation are automatic
Force against displacement of any key or mechanism.
Travel speed adjustment.
Measurement of force on make and break
of the contact and measurement of displacement on make and break of the contact.
Some typical applications are magnetic or relay coils, membrane keyboards, piezo keyboards,
relays, switches, connectors, plugs, sockets etc.
The unit can be connected to a XY-plotter to provide a hard copy of the measured curve
characteristics. The test system includes the adjustable stand with the force and displacement
sensor mounted on a precision slider and the microprocessor controlled electronic unit inside
a 19 inch rack. System applications are quality control, product supervision, development, laboratory design work and incoming and outgoing goods inspection.

System features and advantages:

* operation by untrained personal
* classified test results
* accurate and fast testing of both: force and displacement
* stand alone measurement unit which does not require a PC
* force range from 1 to 10 of from 10 to 100 Newton (500 Newton on request)
* displacement ranges from 0 to 20 mm (up to 50 mm on request)
*  automatic plot of curve characteristics
 
 
Extent of delivery:
* 1 Force / Displacement Test System A 8274 KW with stand and precision slide
   on working plate
* 2 different test fingers
* mains cable
* operating manual

Omnitest has a wide range of modules and system control cards which can be used in any desired combination to solve customer test or production handling requirements.
Multiple tasks such as actuating switches or key boards.pushing,lifting turning,positioning,contacting,and manipulating can easily be achieved as well as optical and accoustical verification of correct performance using our standard ITF series modules.
 These can be integrated into a project at any level from card,module,rack assembly to complete A.T.E. Systems have been supplied for complete telephone testing, handset testing and many projects for production line and test automation.
We also supply Pressure/displacement systems for the evaluation of "touch" or tactile feel of keys or switches or mechanisms. These can be linked to programmable X-Y tables for production testing of keypanels or switches - for example - car horn switches or indeed any mechanism where the switch actuation pressure is critical

 

TEST SYSTEM IEC SYSTEM CONTROLLER

The IEC-Controller A 8274-IEC,certified according to DIN ISO 9001, is a freely programmable control unit which can be connected to a computer via IEEE-488 interface.
The controller is the heart of all ITF Engineering automated systems and when combined with
the various A 8274 modular system cards, it can be utilized to carry out almost any task imaginable such as pneumatic operations, DC motor control, stepping motor control, interrogation of sensors through the use of inputs, activation of relays, activation of current loop outputs, detection of light sources such as LED´s for intensity etc. This equipment is best suited for use in quality assurance, product supervision, laboratory design work, incoming and outgoing goods inspection.
 
System features and advantages:
* operator friendly and easy use
* quick and easy programming
* non-volatile storage (EEPROM)
* once programmed, connection to a PC is no longer necessary
* storage of up to 999 program lines
* free selection of number of active inputs and outputs
* free selection of activation times for all outputs
* control up to 256 inputs and/or outputs
* 5/10 empty sockets for additional ITF Engineering system cards

 
 

The pneumatic system A 8274 PS, certified according to DIN ISO 9001, is a modular, expandible unit which enables the automatic operation of pneumatic functions which would normally be carried out by hand. The pressing of keys, switches, knobs and buttons can now be carried out in a controlled sequence at a pre-selectable mechanical operating pressure in conjunction with either the A 8274 KS-IEC or the A 8274 B unit.
Typical system applications are quality control, product supervision, development, laboratory
design work and incoming and outgoing goods inspection.
System features and advantages:
* modular extension from 16 to 64 outputs in groups of 8 per 19" rack,
   4 racks per system i.e. maximal 256 outputs
* computer interface for remote control
* simple operation of keyboards using pneumatic fingers
* very rapid change over from one configuration to another
* connection of the valve outputs and the tubes via rapid ´instant push-in fittings´
* easy exchangeable cards
* IEC-bus compatible, using real time control via A8274 IEC controller

At the heart of the system is the A-8274 KS/IEC , a freeely programmable control unit which is connected to a PC via IEEE-488 interface. Combined with other cards in the range which will fit into the KS/IEC it can be untilised to carry out almost any function or task such as pneumatic operations, DC motor control, Stepping motor control, interrogation of sensors through the use of inputs, activation of relays, activation of current loop outputs, detection of light sources through fibre links for colour or intensity and many other functions.
