SECTION 6.0, ENHANCED REMOTE PANEL W/MULTI I/O MODULE
6.3.2.5 Power Supply Board
The Power Supply Board produces the +5 VDC logic power for the Enhanced
Remote Panel. It has two connectors - one for input and one for output. The
input wires come from the input power module that contains the line cord
connector power switch, and initial filtering. Surge protection and fusing are
located on the board.
6.3.2.6 Terminal Block P.C. Board
The Terminal Block PC Board mounts to the rear panel and handles all I/O
