Section 2 Preparations
Insulation blocks
2-18
As shown in the following diagram, each function block of the E5AR/
ER is electrically insulated.
<Input> <event input · voltage output · current output> <communi-
cation> are insulated from each other with functional insulation.
<Input · event input · voltage output · current output · communication>
<relay output> <transistor output> are insulated from each other with
basic insulation.
If reinforced insulation is required, input, event input, voltage output,
current output, and communication terminals must be connected to a
device that have no exposed chargeable parts and whose basic
insulation is suitable for the applicable maximum voltage of connected
parts.
