2 POINTBlock dc 16 Input Module

Publication 1734D-IN002A-EN-P - April 2001

Simplified Schematic of POINTBlock

ATTENTION

Whatever field power you supply is connected

to the internal field-power bus. For example, if

120V ac is applied to the power connections,

there will be 120V ac applied to the modules

through the internal field-power bus.

POINT I/O modules to the right of this module

will have this internal power bus voltage

applied, unless you use a 1734-FPD to interrupt

and change the field power-bus voltage.
