BASIC INFO
MTL3000 series MTL3045 ISOLATING DRIVER, 4/20mA for I/P converters has been discontinued for sale.
MTL3000 Series interface units offered a compact and easy-to-use means for communicating safely with process measuring, indicating, actuating and local control equipment in hazardous areas. The comprehensive range of models included analogue, switch and serial-digital signals in both directions, amplifying or otherwise conditioning them as required and at the same time providing world wide certified explosion protection for equipment and wiring in all zones and all explosive atmospheres. It also provided an alternative to the shunt-diode safety barrier where isolation was essential or preferred or a high-integrity earth was not readily available.
The MTL5500 Series are the recommended replacements for this series.
MTL3045 ISOLATING DRIVER, 4/20mA for I/P converters.
The MTL3045 isolates and passes on a 4/20mA or 0/20mA signal from a controller to drive a current-to-pressure (I/P) converter, a
position actuator, or any other load up to 800Ω in the hazardous area. Its high output capability of 16V at 20mA combined with the
low (4V) drop across its input terminals, and its excellent accuracy, make it the first choice for these applications.
