Product Overview

The IO-SA0800Y is an 8-channel analog input expansion module designed to extend the signal acquisition capabilities of Maple Systems modular PLC systems. It accepts both current and voltage signal types across all 8 channels, with each channel individually configurable via DIP switch between current and voltage input modes. 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 push-in 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.
