Description
The KEYENCE KV-AD40 is a standard 4-channel A/D (Analog-to-Digital) conversion unit designed for the KV-8000 series PLCs. This module is engineered to convert analog signals from field devices—such as pressure transmitters, temperature sensors, and flow meters—into high-resolution digital data for the PLC. It supports a wide range of input signals, including both voltage and current, making it a versatile choice for various process measurement and control applications. With its reliable performance and simple configuration, it serves as a fundamental building block for integrating analog signals into KEYENCE automation systems.
