Universal Screw Terminal Panel for DNx-Series I/O
3ft, 37-way round shielded cable
The DNA-STP-37 is connected to 37-pin I/O board via either DNA-CBL-37 or DNA-CBL-37S series cables.
All connections are brought out to standard screw terminals, greatly simplifying your field wiring effort. The board's silk-screen lists pin numbers on both sides of the screw terminals, making it much easier to identify which pin is assigned to a particular screw terminal.
