To connect the high-speed outputs to a relay, LED or similar load, connect the negative side of the load to the output and
the positive side to +24 VDC. When the output switches on, the negative side of the load is pulled down to less than 3
VDC, and 24 appears across the load. Use a protection diode for a large inductive load, with the anode connected to the
output and the cathode connected to +24 VDC.
DataMan 503 Power Requirements
For the DataMan 503 readers, 24 VDC power is provided through the I/O+RS232+24 V cable. Maximum power
consumption is 13 W (High Power Lighting Module).
