SD1015B02-2SN_YOKOGAWA_PRODUCT_吉林易择科技技术发展有限公司

The Yokogawa SD1015B02-2SN is a Digital Input (DI) Module for the Yokogawa FA-M3 series of Programmable Logic Controllers (PLCs).<br /> This module serves as a critical interface between field devices and the PLC's central processing unit (CPU). It is designed to read the on/off status (discrete signals) from field devices such as push buttons, limit switches, proximity sensors, and relay contacts. The module converts these DC voltage signals into digital logic levels (1 or 0) and transmits this data to the CPU via the PLC's backplane for processing within the control logic.
