The page Industrial Process Control Circuits has been updated. This was the PCB of the Transmitter, This would go into the SSR box. It worked pretty well, served the purpose. It was also cloned by others. Now designs are public. In those days, i would try to protect my designs, it was futile. The only edge an engineering company can have to protect its designs is quality, customer support, marketing clout and constant improvement. If you have a Capital-Reserve for cash-flow and dedicated R&D lab and team with very low Attrition; combined with an enthusiastic and adventurous Marketing Team. Then [Read More ....]
This is a prototype of a Preset Counter. It is built with ICM7217. The cabinet is ABS Plastic DIN 96-96. The Panel is Engraved on Acrylic. I don’t remember for which application it was used. It has three thumbwheel settings, when the proximity switch counts upto the set-value, the corresponding relay turns ON, with a State Indicating LED on front panel. These can be configured sequentially or to work synchronously, this depends on what customer wants. Both modes may give the same result. In sequential operation, Some of these counters-timers may need to wait for an external trigger or feedback [Read More ....]
Proportional Temperature Controller This is a Proportional Controller where the setpoint is derived from a Thumbwheel switch. The conversion of Thumb-wheel Digital Data to Analog mV is similar to R-2R Weighted Resistor Network. In this case it is a 1-2-4-8 Binary Weighted Resistor Network. It has no Digital Components. You can see an example circuit below for digit weights you just use like 10K-100K-1M etc. There is a problem of procuring 8M Resistors, so use series parallel combinations, avoid open presets. Trimpots can be used but then it raises the BOM cost. 1-2-4-8 Kilo Ohms may load opamp for high [Read More ....]
