The 9491-PS-PLUS Power Supply is the preferred method for supplying the 9470-ETG 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-PLUS may be mounted in a safe area, Zone 2 or Division 2 hazardous area.
Each 9491-PS-PLUS can power a single Ethernet module. In order to provide multiple outputs required for several Ethernet modules, the 9491-PS power supply module is ganged up to the required number of ways, either DINrail mounted or using the power distribution backplane to simplify the 24VDC input connection to the modules.
