Measurement Specialties CIO-SSH16 user manual Power Cable

Page 6

There are two cables used with CIO-SSH16; a signal cable and a power cable. The power cable (C-PCPOWER-10) is supplied with the CIO-SSH16.

The power cable is black with two white MOLEX connectors. One end mates with the J3 connector on the SSH16 and the other mates with any one of the available PC power expansion plugs inside the PC.

The signal cable (C37FF-# or C37FFS-#) is a 37-conductor cable with 37D female connectors at each end. One end plugs into the P18 connector of the CIO-SSH16, the other plugs into the analog connector of a compatible analog input board (such as the CIO-DAS16). (Figure 2-1).

2.2 POWER CABLE

A separate power cable is required because the CIO-SSH16 draws 1 amp from the +5V supply to power the chips and the DC/DC converter which supplies the analog components with +/-15V. This is more current than the C37FF cable should carry. The C-PCPOWER-10 cable included with the CIO-SSH16 provides ample current carrying capability.

The C-PCPOWER-10 power cable has two connectors, one male and one female. The male end has metal pins, the female end, metal sockets.

The male connector will mate with any of the unused PC power expansion plugs inside your PC. It is likely that there are unused plugs attached to wires which come from the PC power supply on your PC. If not, order the C-PCPOWER-Y adapter to add another connection. Plug the male end of the C-PCPOWER-10 power cable into one of the unused power connectors.

Run the C-PCPOWER-10 power cable out the back of the PC. Use an expansion slot or other orifice. If you prefer a connection external to the PC, the BP-POWER adapter is available to bring the power connector out to a bracket that mounts in an unused expansion slot.

WARNING

Use care so that the C-PCPOWER-10 power cable is not pinched by the PC case. If the cable were severed, a serious short circuit would result, possibly damaging your computer.

Power to the SSH 16 is supplied via a four pin MOLEX connector. This connector is the exact mate of the standard PC Power supply expansion power connector. The expansion power connectors are located inside the PC and carry +5V, +12V and Ground. They are used primarily for disk drive power, but, there are more power expansion connectors than you are likely to use (Figure 4-2) .
