Action Instruments Q406-0000 Analog Input Module

Action Instruments Q406-0000 Analog Input Module is an AC-powered DC input isolator in the ActionI/Q line, engineered to bring DC sensor signals into a controller while providing galvanic isolation between the field and the control system. Powered from 100–240 VAC, this module accepts DC input signals and offers configurable outputs that feed PLCs or controllers in standard ranges: DC voltage outputs of 0–5 V or 0–10 V, and DC current outputs of 0–1 mA, 0–20 mA, or 4–20 mA. In the Q406 family, variants such as Q406-A000 are described as 1 input, 1 output devices and the family is defined as AC-powered DC input multi-channel isolators with a compact housing width of 22.3 mm. The Q406-0000 designation identifies the 100/240 VAC powered input module intended for integration into existing control architectures that require DC signal isolation and conditioning for sensors, enabling reliable data capture in industrial automation, process control, and data acquisition systems.
