44A720084-001 Optional EMI Line Filter
Note
This product is not required on later versions of the Series 90-30 PLC. This
information is provided as a reference for those already using this product. This
item is still available for purchase from GE .
Early versions of the Series 90-30 PLC and its associated hardware components were designed
primarily for use in industrial applications which are, in general, exempted from FCC
requirements. The AC power supply in those early PLCs may not comply with FCC requirements
in non-industrial applications for conducted EMI on AC power lines. In a situation where it was
desired to satisfy the FCC requirements for non-industrial applications, a line filter was used in
series with the AC power line input.
Later versions of the Series 90-30 PLC meet FCC
requirements and do not require a separate line filter.
A line filter that satisfies the FCC requirements for non-industrial applications is available from GE
as part number 44A720084-001. Figure L-1 provides a wiring diagram for connecting the
line filter in a Series 90-30 PLC.
