The Opta PLC may be used in industrial, Internet of Things (IoT), and hybrid applications. We find sensors and actuators at a variety of common voltages (e.g. 5 VDC). In this chapter we explore how to connect these input sensors and output actuators to an Opta PLC. We begin with a review of the Opta input and output characteristics. We then explore a wide variety of digital and analog input sensors and output actuators. We employ an operational amplifier–based transducer interface design process to interface input sensors to the Opta PLC.

摘要

The Opta PLC may be used in industrial, Internet of Things (IoT), and hybrid applications. We find sensors and actuators at a variety of common voltages (e.g. 5 VDC). In this chapter we explore how to connect these input sensors and output actuators to an Opta PLC. We begin with a review of the Opta input and output characteristics. We then explore a wide variety of digital and analog input sensors and output actuators. We employ an operational amplifier–based transducer interface design process to interface input sensors to the Opta PLC.
