The Series SC478 and SCL478 Frequency Isolators / Transmitters allow low cost retransmission of any AC Sine Wave source from 50 mV to 150V RMS and 2 to 10,000 Hz. Featuring push button setup, units can isolate and retransmit to a wide variety of external devices with standard process signals. The SC478 operates on line power so no extra power supply is needed; the SCL478 operates on low power for systems that work exclusively at low voltages. Units mount easily on a standard 35 mm DIN rail and is only 0.886 in (22.5 mm) wide.
