General Information

Model 9700

 

 

 

 

E-to-I Converter

A voltage (E) to current (I) conversion of the output signal generated by the analyzer is available. This conversion allows I (current) to P (pneumatic) devices, as well as low-impedance current-operated indicating and/or recording and controlling instruments to be directly driven without the need of accessory equipment.

One of the following three ranges of current output is available:

1 to 5 mA dc,

4 to 20 mA dc

10 to 50 mA dc.

The designation 326B-I signifies an analyzer equipped with an E to

I converter.

Differential Power Supply

Both integral alarm and E-to-I converter options are plug-in printed circuit boards for quick replacing. When either or both of the options are employed in an instrument, a highly regulated differential power supply (also a plug-in printed circuit board) is included to supply the positive and negative voltage required by the semiconductor circuitry.

The basic Model 326B employs a simple unregulated power supply. The rectifying diodes and filtering capacitors are located on the same circuit board as the detection and amplifier circuitry. The alarm comparator and converter circuits, however, require that the supply voltage remain at a constant level to all circuitry in the interest of accuracy. When options are employed, the unregulated power supply components are deleted from the amplifier board, and the amplifier, as well as the option circuit, are fed from the regulated differential power supply.
