14.2 Connecting Digital Inputs and Outputs of the

RRU 1400 and ARU 2400 Reader Directly

The activation and evaluation of the inputs and outputs is carried out using the

ReaderStart V3

software, with the DLL

supplied or by access to the reader protocol.

The digital inputs and outputs are provided via a printed circuit board connector, 5-pole with open screw connection

with tension sleeve. It is possible to use an industrial isolated wire with a diameter of > 1mm².

The inputs are electrically isolated from the power supply of the reader. The outputs are also DC-isolated from the power

supply of the reader and have a common pin (GND OUT_CMN).

NOTICE

Risk of malfunction!

► Note that the load per channel is limited to a maximum of 0.190 A. The inputs and outputs are

designed for 30VDC max.

► For further information, see the reader data sheet.
