Measurement Specialties CIO-SSH16 user manual Signal Cable, Power Connector

The SSH16 requires 1 Amp of +5 volt power. You may supply this power from the PC, as we recommend, using the cable supplied, or you may use an alternate power supply.

Figure 4-2. Power Connector

Caution on using alternate power supplies: The analog interface from the SSH-16 to the CIO-DAS16 is a single ended voltage signal connection. As such, it is will not reject errors induced by a potential difference between the PC power supply and the alternate supply you use to power the SSH16. Please be certain the PC power supply and alternate power supply share a common ground.

2.3 SIGNAL CABLE

The CIO-SSH16 signal connector is nearly a mirror of the CIO-DAS16 signal cable in 16 channel mode (Figure 1-2). There are two 37D connectors on the CIO-SSH16 wired in parallel. The second, P19, permits daisy chaining signals to other signal conditioning or screw terminal boards.

Use any 37 conductor ribbon cable with female D-37 connectors to connect a CIO-SSH16 to a CIO-DAS16 or other compatible analog input board. The cable length should not exceed 10 feet.

Connect one end of the signal cable to the analog input boards analog connector and the other to the CIO-SSH16 P18 connector.

A shielded cable (C37FFS-#) is preferable if EMI or RMI is present with sufficient energy to interfere with noise free measurements. The connection between the CIO-SSH16 and the analog input board is single ended so signals on the cable have no common mode noise rejection.

The signals labeled P13, P14, P15 & P16 (Figure 1-2) correspond to the four screw terminal blocks where other signals coming from or going to your A/D board may be
