About the Power Supplies
The power supply is an essential component in the operation of an
intrinsically safe system. It must isolate the unsafe incoming power from the
control system and limit the available energy to IS-safe levels.
No other power sources are needed to operate any components attached to
the FLEX Ex system in the hazardous area. Power for valves, actuators, or
transmitters come from the FLEX Ex modules.
The 1797-PS1N is a 85…250V ac in/quad-Ex dc out power supply in an
explosion-proof enclosure with 1 in. conduit pipe-thread input/output
terminations.
