Mitsubishi Q68AD-G is an 8-channel analog input module designed for current and voltage signals. It supports input ranges of DC -10 to 10 mA and 0 to 20 mA, offering flexible resolution settings including 0 to 4000, -4000 to 4000, 0 to 12000, -12000 to 12000, 0 to 16000, and -16000 to 16000. The module features a conversion speed of 10 ms per channel and is equipped with a 40-pin connector. It provides channel-to-channel isolation, which enhances measurement accuracy and ensures high isolation voltage. This isolation type eliminates the need for external isolation amplifiers, reducing hardware and installation costs. The module supports process control applications by allowing direct connection of field devices such as flow meters, pressure gauges, and other sensors. It also supports direct connection to control valves via analog output. The Q68AD-G offers high dielectric strength and is resistant to electrical interference such as noise and current surges. It is classified as a standard analog input module with isolation capabilities. When using channel-isolated analog modules, the system can achieve improved reliability and signal integrity without the need for additional external components. This expands the potential for intelligent function-based control in programmable logic controller (PLC) systems.
