| As shown in figure "A" of the illustration, concerning the signal conditioning circuit for programmable logic controller as illustrated, which statement is true? |
| A) If the sensor input voltage signal delivered to the inverting input is less positive than the reference input signal voltage signal delivered to the non- inverting input, the amplifier output voltage will be positive. |
| B) If the sensor input voltage signal delivered to the inverting input is less positive than the reference input signal voltage signal delivered to the non-inverting input, the amplifier output voltage will be negative. |
| C) If the sensor input voltage signal delivered to the non-inverting input is less positive than the reference input signal voltage signal delivered to the inverting input, the amplifier output voltage will be positive. |
| D) If the sensor input voltage signal delivered to the non-inverting input is less positive than the reference input signal voltage signal delivered to the inverting input, the amplifier output voltage will be negative. |
