The inputs and outputs are designed for max. 30 V DC. For further information see the data
sheets.
u
Load the digital inputs and outputs with max. 0.5 A.
u
Load the used digital inputs and outputs with max. 1.5 A in total.
u
If the auxiliary voltage of the GPIO connection of the device is used, load the used digital
inputs and outputs with max. 1.1 A in total.
u
For operation of the outputs with an external voltage source, only use LPS (Limited Power
Source) or NEC class 2 power supplies.
7.5 Antenna connection
Up to 4 RFID antennas can be connected via the antenna connections. The antenna connections are
designed as reverse TNC.
