Description

RISH CON SI101 is a powerful signal isolator suitable for a variety of applications. It operates passively and does not require a separate power supply, but derives the auxiliary energy it needs from the DC signal. The SI-101 amplifies and/or changes the signal level or type (voltage/Current) of the input signal. The Rish Con DC Signal Isolator can be used to isolate the 4…20 mA current signal from a 2-wire thermocouple transmitter or temperature controller, and pass it on to a PLC or data logger. SI 101 eliminates earth and ground loop problems and simplifies interfacing. The isolator complies with all the requirements for EMC and safety (IEC 61010).
