Sir,
I am Ganapathi Sundaresan, Working as Assistant Engineer in Tamilnadu Electricity Board, Chennai. At present for Transformer Protection with remote end trip we are using INTERFACE UNIT ( RS 232 Compatible) for TX and RX Data through Radios or BSNL Lease Line Circuit ( 2 Channel input and 4 Channel Output ) Frequently we are facing problems in micro controller and in sum of the units the micro controller has failed. We are unable to replace the micro controller since we don't have program and micro controller chip in locked condition.
We are interested in replacing the older model with latest technology scheme. Can you suggest which model of TEXAS Instruments is more suitable for protection system with Operating voltage
12 V or 48 V or 110 V DC kindly conform the suitable model with price and terms and condition for procurement purpose. We are in urgent need of replacement
