This DS200PTBAG1B offering is somewhat interestingly definable as a Protection Termination Module, given its DS200PTBAG1B functional product number's assertion of a normal Mark V Series assembly version.
The IS200EDEXG1A board receives power from the ESPM module, the power that should be received from that module should be 24 VDC; the EDEX module will then turn the power received into 125 VDC.
