9000Ex-31 and 9000Ex-32 are single-channel Smart Current Drivers that provide a galvanically isolated 4–20 mA signal to the hazardous area, corresponding to a 4–20 mA input signal from the safe area. They repeat the current signal in another floating circuit to drive a hazardous area load, using isolating transformers that provide galvanic isolation. The Smart Current Driver operates SMART I/P converters, electric valves, and positioners in hazardous areas. It
features high output capacity combined with a low voltage drop across its input terminals.

Masibus 9000Ex-1/9000Ex-2 Repeater power supply/ Signal Isolator is compact and rugged for Isolation of field signals from Hazardous area. It provides a fully floating dc supply for energising a conventional 2-wire/3-Wire 4-20mA transmitter or smart transmitter, which is located in Hazardous area. It repeats the current in another floating circuit to drive a safe-area load.

Masibus 9000E is compact DIN rail mount Signal Isolator which is used to isolate 4-20mA Analog Field Signals. Separate Inbuilt Transmitter Power supply is available in each channel to energise the 2-wire field Transmitter, and this will eliminate the requirement of external Transmitter Power Supply. 9000E is suitable for 2-W and 4-W Field Transmitters.

Masibus 9000L Signal Isolator is compact yet rugged 4 wire Isolator used for reliable isolation and attenuation of Industry Standard Field Signals. 9000L is available in Single or Dual output models.

Masibus 9000U+ Signal Isolator is available in single or dual output models. 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 9000C has higher noise rejection ratio that ensures accurate and noise free signal conditioning. Its Slim DIN rail mount design occupies less space and reduces cost of overall installation. With DOP (AP only), 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.
