Description

9492-PS-PLUS Intrinsically Safe Power Supply Ex ia/ib (12.8V)

9492-PS-PLUS Intrinsically Safe Power Supplies (isolated power supplies) are ideal for providing power to instrumentation in hazardous process areas. The 9492-PS-PLUS is the preferred method for supplying 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.

  • Isolated power supply
    • Zone 2 mountable
    • DIN-rail or backplane mounting
    • ATEX / IECEx certified
    • 480mA @ 10.00V DC – Ex ia IIB
    • 550mA @ 11.90V DC – Ex ib IIB output
    • Power over Ethernet option
    • Multiple outputs achieved by ganging 9492-PS-PLUS modules using 24V DC power distribution backplane
    • Wide operating temperature −40°C to +70°C

Additionally, 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.
Each 9492-PS-PLUS can power a single ethernet module. In order to provide multiple outputs required for several ethernet modules,
the 9492-PS-PLUS power supply module is ganged up to the required number of ways, either DIN-rail mounted or using the power
distribution backplane to simplify the 24VDC input connection to the modules.

The 9492-PS-PLUS module has LED power indication for both input and output along with internal current limiting and electronic auto-reset circuit breaker action to protect the module in the event of its output being short circuited or overloaded. This also minimises the power dissipation during the fault to a negligible level, thus improving reliability.
