Overview
IPC402x consists of two or three printed circuit boards; base board, front board and, if applicable, an
expansion board. Overview pictures of IPC4020/IPC4020exp and IPC4022 are shown in Figure 1 and
Figure 2.
Overview IPC4022. The output 3 is routed to a power relay.
More detailed descriptions of the devices can be found in the datasheet for each device [1][2].

The only normal reason to remove the front cover of the devices is to check the identification stickers that
are located on the printed circuit boards. Each circuit board has a unique identity with the following format,
see example beneath.
