data lines must meet the following specifications:
Supply Voltage: 12-24 VDC
Ripple: 5% of input voltage p-p (max.)
Noise: 5% of input voltage p-p (max.)
Supply Current
12 VDC 250 mA operating (300 mA inrush)
24 VDC 125 mA operating (300 mA inrush)
Parallel Port: (17 inputs maximum)
5 VDC 3.0 mA per input (typical)
12 VDC 7.3 mA per input (typical)
24 VDC 14.6 mA per input (typical)
Fusing: External fusing should be provided.
After the DL5 has been mounted, the necessary wiring can be connected to
the DL5. The following figure illustrates the terminal connections located
on the back of the DL5. Perform the following steps to connect wiring to
the DL5.
