CIO-TERMINALCIO-SPADE50

This universal screw terminal accessory provides easy signalconnection to miniature screw terminals which accept 12-22
American Wire Gauge (AWG) wires.

Due to their ruggedness and larger size, spade lugs are preferredover screw terminals by some industrial customers. TheSPADE50 is a versatile 16" X 4" termination panel which mateswith both 37 pin and 50 pin connectors.

Any I/O board with a 37 pin signal connector may employ theSpade lugs are available from Radio Shack and industrial hardCIO-TERMINAL for signal termination. Its large size (16" Xware suppliers.

CABLE CONSTRUCTION KITS

CUSTOMIZED SCREW TERMINATION PANELS

Cables may be constructed from your choice of signal wire and aconnector kit. The connector kits, DFCON-37 and DMCON-25
consist of a 37 or 25 pin 'D' connector, crimp pins and a shell. The
crimp pins are crimped onto your signal wire then pushed into the'D' connector. A shell protects and professionalizes the assembly.
Shown below is the DFCON-37.

Signal routing and termination can be a hassle. It seems that nobody
makes exactly what you need, or they charge an arm and a leg!

CIO-MINI37 & CIO-MINI50
The economical CIO-MINI37 is just the screw terminal accessory
for tight places; or tight budgets. Measuring only 4" by 4", the CIOMINI37 mates with the C37FF series of cables and thereby to any
I/O board with a 37 pin connector.
It is truly a universal screw terminal accessory because all thesignals from the 37 pin connector are brought directly to a numbered 12-22 AWG screw terminal. The number on the screw
terminal corresponds to the number on the 37 pin connector.
The CIO-MINI50 provides the same functionality and size for I/Oboards that employ the 50 pin header connector.

A NOTE ON CABLES & CONNECTORSThe cables we offer are universally equipped with female connectors at each end. The female connectors on the cable are intended
to mate with the male connectors found on I/O boards and screw
terminal and signal conditioning accessories.
The male connector is always mounted on the board because, of thetwo, the female connector is more likely to wear out. The tiny
sockets in a female connector spread with frequent insertions andremovals, eventually resulting in too loose a fit for a good signal.
It is more economical to replace a cable than a board.
