MicroDIN
- Programmable Isolating Signal Converter with preset (Sq Rt,
etc) and User Defineable Linearisation Functions |
|
Function:
Isolating signal converter which will convert a range of process
signals into standard transmission voltage or current signals.
The MicroDIN is a microprocessor based signal converter that
can carry out: signal conversion; thermocouple linearisation;
special functions, such as Square Root Extraction, etc. Both
the input and the output stages of the instruments are powered
from separate secondaries of the transformer thus maintaining
3 port isolation. The MicroDIN is programmable with the programming
function resident in memory. To programme the MicroDIN you
need to connect it to a terminal/PC via a Lee-Dickens MicroLEAD.
The MicroLEAD is a TTL to RS232 converter and comes with a
software package that will make your PC emulate a terminal.
With the Lee-Dickens MicroLEAD you can programme the input
and output type and range and the function required.
Power supply: mains or DC

L900
- Programmable Isolating Signal Converter with preset (Sq Rt,
etc) and User Defineable Linearisation Functions |
|
Function:
The L900 is a programmable microprocessor based isolating
signal converter which will convert a range of process signals
into standard transmission voltage or current signals. The
programming function is resident in memory. The L900 can carry
out: signal conversion; thermocouple linearisation; special
functions, such as Square Root Extraction, etc. Both the input
and the output stages of the instrument are powered from separate
secondaries of the transformer thus maintaining 3 port isolation.
Connect the L900 to a terminal via a Lee-Dickens MicroLEAD
and change the input and output type and range and the function
required.
Power supply: mains or DC

MicroMATH
- Programmable Analogue Maths Module |
|
Function:
An analogue computation/mathematical module which can handle
up to six analogue (mA) inputs and carry out a number of mathematical
functions before outputting a standard transmission voltage
or current signal. The MicroMATH is microprocessor based and
offers a comprehensive range of mathematical operands. The
MicroMATH is programmable with the programming function resident
in non-volatile memory. Connect the MicroMATH to a PC/terminal
via a Lee-Dickens MicroLEAD and set up the algorithm required.
This can be a simple addition of several inputs to a more
complicated algorithm containing Constants, Conditional Transfer
Commands, Straight Line Approximations, etc. For example,
MicroMATH can easily handle Mass Flow Calculations in the
one instrument or more complex algorithms using cascaded units.
Power supply: mains or DC
