Signal Isolator

Masibus Automation & Instrumentation offers a Signal Isolator, Model 9000U. This is a rugged 4-wire isolator designed to accept custom built and wide range of voltage and current input signals. Signal is then isolated and converted to standard instrumentation signals, acceptable to commercially off the shelf (COTS) automation products. The unit enables analog signals to transmit without galvanic connections between the field and the receiving instrument. This in turn allows ground or reference levels to float up to thousands of volts at its input terminals, and prevents circulating current between differing ground potentials that can contaminate input signal. Model 9000U will isolate the contaminated signal to a clean signal for accurate measurement and control application. Isolation provided by Masibus Model 9000U saves the control system from damage due to accidental application of high voltage or induced voltages on the input signal and in turn avoids wrong output signals to process. They also act as signal distributors when used with more number of outputs. Model 9000U series is available with multiple outputs up to 2, for signal distribution. A typical application could be where the signal has to be distributed for indication on local panel/field control room/main control room and DCS system. The isolator provides a good protection for sensitive system parts against voltage spikes, etc. Model 9000U offers a wide range of input/output signal types include mA, mV, V DC. Built-in transmitter power supply (TPS) can drive field transmitters in case of 4-20 mA DC input. Model 9000U offers excellent accuracy and stability for reliable operation in hostile environments and full isolation safely separates each input channel, each output channel and the power supply. Features: rugged and accurate 4-wire isolator; three port isolation; accepts non-standard signal input option; input voltage – ?10 mV to ?600 V DC, current – ?1 mA to ?100 mA, mains/DC operated; up to 2 outputs of different types available; DIN rail/back panel mounted; built-in transmitter powering; duplex isolator version option; and wide zero and span adjustment limits.
