Warning
S Use only PELV circuits as per IEC/DIN EN 60204−1 (Pro
tective Extra−Low Voltage, PELV) for the electrical supply.
Consider also the general requirements for PELV circuits
in accordance with IEC/DIN EN 60204−1.
S Use power supplies which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN EN
60204−1.
By the use of PELV circuits, protection against electric shock
(protection against direct and indirect contact) is guaranteed
in accordance with IEC/EN 60204−1 (Electrical equipment for
machines, General requirements).
The CP input module must be earthed to ensure that it func
tions correctly (e.g. EMC).
The connected sensors are supplied with + 24 V DC via the
connection for the sensor supply. The module enables sen
sors with high current consumption to be connected (max.
125 mA per sensor).
