E-770 SERIES TEMPERATURE CONVERTERS DESCRIPTION E--770 series devices are rail-mountable industrial devices in a plastic case designed to be used as signal converters. E-770 series converters convert resistance thermometer (RTD) and thermocouple (TC) type temperature sensors, resistance and DC mV signals to standard 4 - 20 mA output signals. The input and output signals of the E-770 series devices are not galvanically isolated. E-770 series converters can be ordered as 2-wire or 4-wire types. In 2-wire types, the operating voltage and output signal are not galvanically isolated, in 4-wire types, the operating voltage and output signal are galvanically isolated. E-770 series converters can be configured with special PC software provided by Elimko.
