Model 518 is an advanced, eight-channel sensor measurement system on a PC/104 board. It provides excitation for passive sensors and complete signal conditioning for thermocouples, RTDs, thermistors, and strain and pressure gauges. Each channel can be individually configured to measure voltage, resistance, or any supported sensor type.
-12V power supply
- My SBC does not provide -12V power to the PC/104 stack. Does the 518 require -12V power?
Yes, the 518 requires -12V, so your SBC must provide this operating voltage to it. SBCs usually have some sort of provision for this because the PC/104 specification mandates -12V (though some SBC manufacturers omit it to save money, thus violating the spec).
You can easily check for the presence of the three required power supply voltages (+5V, +12V, -12V) by probing test points shown in the image on the right.
