Product Overview
The IO-SA0400Y is a 4-channel analog input expansion module designed to extend the capabilities of Maple Systems modular PLC systems. It accepts both current and voltage signal types, making it well-suited for interfacing with a wide range of industrial sensors and transducers. With a conversion speed of under 0.5 ms and selectable resolution of 14-bit or 16-bit, the module delivers fast and precise analog measurements. Connections are made via a screw-based terminal connector, and the module is powered by an external 24 VDC supply. It is configured and programmed through MapleLogic, Maple Systems’ free PLC software.
