Eaton's Crouse-Hinds series range of MTL intrinsically safe (IS) 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 - 17.7V, offering flexibility of options to best suit a variety of applications. 

• 9491-PS-PLUS models: Safe area / Zone 2 mount power supply that takes standard 24V DC input and produces an intrinsically safe, 12V DC nominal output. Capable of powering the Ethernet modules and other IS devices - with Ex ia output (up to 200mA) for devices mounted in Zone 0, and Ex ib output (up to 400mA) for devices mounted in Zone 1 Gas Group IIB hazardous areas. 
  
• 9492-PS-PLUS models: Safe area / Zone 2 mount power supply that takes standard 24V DC input and produces an intrinsically safe, 12V DC nominal output. The optimum solution for powering MTL 947x-ET/G Ethernet modules and other IS devices - with Ex ia output (up to 200mA) for devices mounted in Zone 0, and Ex ib output (up to 400mA) for devices mounted in Zone 1 Gas Group IIB hazardous areas.
  
• MTL 9493-PS models: Safe area / Zone 2 mount power supply range that takes standard 24V DC input and produces intrinsically safe, 5.4 to 18V nominal output. With Ex ia output for devices mounted in Zone 0 and Zone 1, Gas Group IIB and IIC hazardous areas.
