MTL 949X Power Supplies

The MTL 949X intrinsically safe isolated power supplies are ideal for providing power to instrumentation in hazardous process areas. They offer a wide range of different IS output voltages, ranging from 4.8V to 17.7V, offering flexibility of options to best suit a variety of applications. The 949X can also be used with the 946x-ET range of MTL IS Ethernet devices to provide direct power or IS Power over Ethernet (PoExTM), a method which allows a single cable to provide both the data connection and electrical power to devices, in turn, reducing installation costs.

The MTL 949X is available in three configurations:

The 9491 power supply is the preferred method for supplying the 9460-ET series of intrinsically safe Ethernet modules and is based on an isolating power supply. It takes a 24V DC safe area / Zone 2 / Division 2 supply and produces an intrinsically safe, 12V DC nominal output capable of powering the Ethernet modules mounted in a Zone 1/ Division 1 hazardous area. The 9491-PS may be mounted in a safe area, Zone 2 or Division 2 hazardous area.

The 9492 power supply is the preferred method for supplying the 9460-ET series of intrinsically safe ethernet modules and is based on an isolating power supply. It takes a 24V DC safe area / Zone 2 supply and produces an intrinsically safe, 12V DC nominal output capable of powering the ethernet modules mounted in a Zone 1 hazardous area. The 9492-PS-PLUS may be mounted in a safe area or Zone 2 hazardous area.

The 9493 power supply is a general purpose Intrinsically Safe power supply unit. It takes a 24V DC safe area or Zone 2 supply and produces an Intrinsically Safe output available in a range of different DC voltages. The 9493-PS-XXX may be mounted in a safe area or Zone 2 hazardous area.
