K2635 8 TO 1 ANALOG MULTIPLEXER
In most measurement and control systems, several analog
variables have to be measured or guarded. The combination of an analog
multiplexer card and one single A/D converter K2610 replaces the use of eight
single A/D converters, which is not only less expensive, but especially
space-saving and leaves some room for other I/O functions.
The software for this card cannot be more simple: with one
single instruction you chose another input. The output is buffered and can
amplify the input-signal up to 5 times.
There is space for an attenuator on each input.
A motherboard K2612, which buffers the computer signals,
generates the necessary auxilliary signals and takes care of the
interface-card-power supply, allows for the connection to the computer.
Schema
Technische Daten:
The possibility to attenuate each input separately.
Input impedances of more than 1 mega-ohm are possible.
Buffered output: min, load resistance is 1 kilo-ohm.
The output signal can be amplified (max. 5 times)
Fast response: the output is stable within 1 ms. after the selection command.
Explanation for the programming of the card (in Basic) in the manual.
8-bit address decoding on the print.
The (5V/40mA and 9V/20mA) power supply is taken care of by the motherboard
Dimensions : 106 x 106 mm.
