The Series SC468 and SCL468 AC Current and Voltage Isolators/Transmitters allow low cost retransmission of any AC current (10 mA to 100 mA) or voltage (100 mV to 200 V). Quickly setup, they can isolate and retransmit to a wide variety of external devices into standard process signals. The SC468 operates on line power so no extra power supply is needed; the SCL468 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 22.5 mm (0.886 in) wide, allowing space for other equipment.
