The Mitsubishi branch module LJ71E71-100 is a key component in industrial automation systems, characterized by a DC5V internal current consumption of 0.08A and a weight of 0.12kg.

1. The field input interface module consists of an optical coupling module and a microprocessor-based input interface module. Its primary function is to serve as the input channel between the programmable logic controller (PLC) and the field control interface. This module ensures electrical isolation and signal integrity, allowing the PLC to reliably receive status signals from sensors, switches, and other field devices.

2. The field output interface module integrates an output data register, a selection module, and an interrupt request module. Its role is to enable the PLC to transmit control signals to field actuators and execution units. By converting internal logic signals into appropriate output commands, this module facilitates precise and timely control of devices such as motors, valves, and relays, thereby supporting efficient automated operation.
