Loop Powered Isolator

Masibus 9000U Series Loop Powered Isolator

Masibus 9000U+loop powered isolator is compact yet rugged 4 wire Isolator used for reliable Isolation and Attenuation of Industry Standard Field Signals. 9000U+ is available in Single or Dual output models. 9000U+ has higher noise rejection ratio that ensures accurate and noise free signal conditioning. It’s Slim DIN Rail mount design occupies less space and reduces cost of overall installation. With Dual output option this model also acts as Signal distributor. A typical application could be where the signal has to be distributed for indication on local panel, field control room, main control room or DCS system. The Isolator provides a good protection for sensitive system parts against voltage spikes etc.

Model 9000U+ has built-in transmitter power supply (TPS) to drive field transmitters delivering 4-20mA DC outputs signal. An exceptional feature of advanced extended universal power supply for the range of 20V to 265V DC or AC makes 9000U+ suitable for most of the power supply range available in field thus providing easy installation. Masibus’ 9000U+ Model offers an excellent accuracy and stability for reliable operation in hostile environments and full isolation safely separates input channel, each output channel and the power supply.
