Product Features
ABB DI814 features 16 digital input channels, supporting current source-type inputs (24V DC), enabling simultaneous acquisition of multiple field signals.
ABB DI814 inputs are divided into 2 independent isolated groups (8 channels per group), with each group equipped with 1 voltage monitoring input to reduce interference and enhance system safety.
ABB DI814 is equipped with front-panel LED indicators, including fault (F), run (R), warning (W), and 16 channel status indicators (“0” or “1”), facilitating quick diagnosis.
ABB DI814 supports selectable digital filtering times (2, 4, 8, 16 ms) to suppress noise based on the field environment and ensure signal stability.
ABB DI814 supports process voltage monitoring (1 channel per group), and channel error signals can be read via ModuleBus for remote maintenance.
ABB DI814 complies with multiple industrial certifications and can operate in harsh environments such as wide temperature ranges and high humidity, with an IP20 protection rating.
Product Using Principle
ABB DI814 collects switch signals from field devices (such as limit switches, proximity sensors, buttons, etc.) and converts physical states (on/off) into electrical signals (high/low levels). Internally, the module processes signals using current limiting, EMC protection, and optical isolation components, followed by noise suppression via a filtering circuit. The stable digital signals are then transmitted to the upper-level controller (such as a PLC or DCS) via ModuleBus. Additionally, the module provides real-time feedback on its own status and channel status through voltage monitoring and LED indicators, ensuring reliable data transmission.
