The Yokogawa DM1045B60 is a Digital Input Module designed for use with the Yokogawa FA-M3 series of programmable logic controllers (PLCs).
This module acts as an interface between field devices and the PLC's main CPU. It is responsible for reading the on/off status (discrete signals) from devices like push buttons, limit switches, proximity sensors, and relay contacts, converting these signals into a digital format (1 or 0), and transmitting this data to the CPU for logic processing.
