Description

ABB LDGRB-01 3BSE013177R1

ABB LDGRB‑01 3BSE013177R1 is a digital input (DI) module that serves as a core component for field signal acquisition in industrial automation control systems. It belongs to the ABB S800 I/O series and is compatible with the System 800xA and AC 800M high‑performance control systems. Integrating five core capabilities—high‑precision digital signal acquisition, strong anti‑interference performance, comprehensive diagnostics, hot‑swap capability, and high compatibility—it is an important part of ABB’s industrial automation solutions.This module safely, reliably, and accurately converts various dry contact or passive contact signals from the field into digital signals recognizable by the controller. It is widely used in energy and power, industrial machinery, water treatment and environmental protection, marine engineering, automotive manufacturing, chemical engineering, and other fields. Suitable for various industrial automation systems, programmable logic controllers (PLC), and distributed control systems (DCS), it acts as a forward data acquisition outpost connecting field devices and control logic, providing reliable data support for industrial process control, equipment condition monitoring, and operation and maintenance management.


The module is mainly used for high‑precision acquisition of digital signals in industrial field applications. Its core function is to receive dry contact or Namur proximity switch signals from field devices such as pushbuttons, limit switches, relay contacts, and proximity sensors, convert them into digital signals identifiable by the system, and upload them in real time to main controllers such as the AC 800M via the backplane bus, providing accurate field status data for control logic execution.It features channel‑group isolation, which effectively suppresses crosstalk between channels and field common‑mode interference, ensuring accurate signal acquisition in complex electromagnetic environments. It is also equipped with comprehensive diagnostic functions, including module internal status diagnosis, field power supply monitoring, and wire break detection (with external resistors), enabling early detection of potential faults and predictive maintenance.The module is deeply integrated into the ABB industrial automation ecosystem, supporting seamless integration with S800 I/O stations, System 800xA, and AC 800M control systems. It works with communication interface modules such as CI853 and CI854, complies with relevant industrial automation standards, and provides excellent vibration and electromagnetic interference resistance, ensuring compliance and long‑term reliable operation in various complex industrial environments.


It adopts a compact industrial modular design for easy installation and user‑friendly maintenance. The plug‑in structure allows quick mounting on S800 I/O base units (such as the SD822 power/communication base and SA801 extension base), facilitating later removal and replacement. Clear LED status indicators enable rapid identification of power, operation, fault, and communication statuses for convenient on‑site troubleshooting.The housing uses industrial‑grade protective materials with excellent resistance to electromagnetic interference, dust, moisture, and vibration, suitable for harsh industrial environments such as compressor rooms, ship engine rooms, and painting workshops, supporting long‑term stable operation.It also supports hot‑swap operation, allowing replacement of faulty modules while the system is running without interrupting other channels, ensuring uninterrupted operation of critical loops and meeting the strict requirements of continuous process industries.

2. Features


  1. High‑density digital input for versatile applications16 digital input channels in a compact design save significant cabinet space—up to 40% compared to conventional layouts. Supports both dry contacts and Namur proximity switches with 24 VDC detection. Widely compatible with field pushbuttons, limit switches, relay contacts, and sensors to meet various industrial signal acquisition needs.

  2. Strong anti‑interference design for accurate and reliable acquisitionChannel‑group electrical isolation (opto‑ or magnetic coupling) blocks common‑mode interference and crosstalk caused by ground potential differences. Wide threshold levels and dedicated filtering avoid false triggering. Each channel is sampled independently and accurately even in severe electromagnetic environments, providing a solid foundation for safe control logic.

  3. Comprehensive diagnostics enabling predictive maintenanceBeyond basic signal input, the module provides internal diagnostics, field power monitoring, and wire break detection. Faults are detected early and reported to the controller, supporting predictive maintenance instead of reactive repair. This greatly improves system availability and reduces unplanned downtime.
