ROTOSCAN RS4-4
Electrical Connection
|
|
|
The ROTOSCAN RS4-4 requires a direct voltage of 24 V and 8 W of power plus the load at the outputs (max. 25 W).
In keeping with electrical safety requirements, the power to the ROTOSCAN RS4-4 and all connected input and output circuits must be provided by a power supply unit with protective isolation from a safety transformer according to IEC 742 or comparable (this also applies for the use of battery chargers for AGV applications).
