A voltage output signal is an analog output signal commonly used in pressure, temperature, and other types of sensors. Within the realm of voltage output, there are a variety of I/O options, including the ones in the table below.
The most common voltage output signals, especially where power consumption is not an overriding consideration, are 1-5VDC, 1-6VDC and 0-10VDC for industrial applications.
With the growth of IoT & IIoT projects that incorporate sensors, the capability to operate from low power with less current consumption is valuable, especially for equipment being deployed in remote areas where frequent battery changes are costly and time consuming.
To address low power needs, there are a number of voltage output options that can be powered from 3V, 3.3V, 3.7V, 5V, and 9V power supplies and batteries. The voltage output signals commonly paired with these supply voltages are*: millivolt, 0.5-2.5VDC non-ratiometric and 0.5-4.5VDC ratiometric. The option for 0.5-2.5VDC output is rapidly growing in popularity because of the increased use of 3 to 5VDC lithium ion batteries. Click here to learn more about this low power option.
