Users of CTC Series signal converters can use a standard, 5-amp secondary CT or low-voltage (0.333 VAC) ProteCT current transformer with non-contact ranges as low as 0-5 A over a conductor to produce a standard 4-20 mA, two-wire, loop-powered signal. With DIN-rail mounting and a 24 Vdc loop-powered supply, CTC series provides simple, snap-in installation that requires no calibration.
