Signal convertor upgrades legacy applications
A
Lee-Dickens product story
Edited by the Engineeringtalk editorial team

The BD940 is a signal convertor that will add or subtract between two and four scaleable input current or voltage signals and one internal scaleable constant.
Lee-Dickens is to manufacture a four channel analogue adder/subtractor for like-for-like replacement of products in existing applications.
The company reckons that the current product serving the market has become ever harder to source and feels it is perfectly positioned to produce a cost effective replacement product for the many hundreds of existing applications in the nuclear, steel and utilities industries.
The BD940 is a signal convertor that will add or subtract between two and four scaleable input current or voltage signals and one internal scaleable constant.
The BD940 then converts the resultant into an isolated standard transmission voltage or current signal.
Each channel can be added to or subtracted from the equation by means of links, now located behind the easily accessible front panel (the only major improvement to the original product) and each channel has a scaling potentiometer for overall gain control.
Setting up the scaling for each channel is affected by reference to an internal voltage brought out to the external terminals.
The BD940 can be supplied with either a 115 or 230V AC power supply.
A 9-30V DC option is also available (model number BM940).
The unit has an operating temperature range of -20 to +60C and works in humidity up to 95%.
The Lee-Dickens manufacturing centre in Northamptonshire is able to produce this high quality, but now niche product at a reasonable cost.
The BD940 enables end users to replace current equipment and extend the life of the plant without having to buy new racks or spend vast amounts of time and money rewiring.
Furthermore, replacing like-for-like products in specialist applications will remove the requirement for retraining and may negate the requirement for submitting a new safety case.
