Problem: Even with a current transformer, a dangerous 0-5 amp AC signal enters our instrument cabinet. We would like to keep power levels in a safer range for our instrument technicians.
Solution: Install an ECT with the -EM option. It provides a “mini” external input transformer to step down the 0-5 amp signal to a lowlevel 0-5mA signal into the ECT. The ECT then transmits a 4-20mA signal to the receiving instrument. This permits safe servicing without disconnecting the main CT.
