The Yokogawa SD1045B62 is a DC Input Module for the Yokogawa FA-M3 series of Programmable Logic Controllers (PLCs).
This module is a key interface component that connects field devices to the PLC's central processing unit (CPU). It is designed to read the binary on/off status (discrete signals) from a group of field devices such as pushbuttons, selector switches, proximity sensors, and relay contacts. It 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 use in the control program.
