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.
