The ABB 3BSE008538R1, also known as the DI810, is a high-performance 16-channel digital input module designed for the versatile S800 I/O system. This module is engineered to process 24V d.c. signals from various field devices, such as sensors and switches, and transmit them reliably to the control system. A key feature of the DI810 is its full galvanic isolation, both between individual channels and from the module bus, which enhances signal integrity and protects the system from electrical disturbances. Its robust design ensures dependable operation in demanding industrial environments, making it an ideal choice for process control and automation applications using ABB’s AC 800M or Advant controllers.
