Electrical Connection; Wiring Diagram Transmitter; Configuration Protected Area Width (Range) - IFM OY Series Original Operating Instructions

7 Electrical connection

► Disconnect power. Also disconnect any independently supplied relay load
circuits.
The nominal voltage is 24 V DC. This voltage may vary between 19.2 V and
28.8 V.
In case of a single fault the supply voltage must not exceed a maximum
of 28.8 V DC. Therefore a safe separation between current supply and
transformer is necessary.
To guarantee functional reliability an output capacity of min. 2000 µF / A has
to be ensured if a power supply with diode bridge is used.
► Connect the devices to the following table:
