Masibus Signal Isolator

9000C Series Masibus Signal Isolator

9000C Series Masibus Signal Isolator is compact yet rugged 4 and 2 wire Signal isolators designed for conditioning and safe guarding custom-built wide range of voltage and current  field signals. Field Signal is then isolated and converted to standard instrumentation signals, acceptable to commercially off the shelf (COTS) automation products.

The Aux Powered Model is Equipped with Advanced Extended Power Supply with Supply Range of 20V to 265V AC or DC. 9000C model is further enhanced with Switch selectable I/O configuration for I/O ranges i.e. 0/4-20mA, 0/1-5V and 0-10V. This feature allows user to have freedom to change 0/4-20mA, 0/1-5V and 0-10V I/O types only, using switch available on side of device and with minor tuning using front accessible trim-pots, depending upon field requirements.
