SIGNAL ISOLATOR SC301

SC301 is a dual purpose, current-to-current converter with 3-port isolation. It is HART compatible; HART technology superimposes digital communication on top of the 4-20 mA signal for two-way field communication so that the transmitter can be interrogated either from the operator station or by a handheld configurator. It provides a fully floating, isolated DC supply for energizing a conventional 2 or 3-wire 4 - 20 mA transmitter/smart transmitter and repeats the current in another isolated circuit or accepts a 4 - 20 mA signal from a controller/source to drive loads up to 750W. A 20 - 35 V DC power supply is required for operation. The power supply terminations are at the top of the unit to enable this model to be used either as a repeater power supply or driver. SC301 provides galvanic isolation between its own power supply, the input and output signals up to 1.7 KV AC/DC continuously and has a transfer accuracy better than 20 ?A. SC301’s microcontroller technology linearizes the input which makes control more effective.
