O3EHa HENF315087R2
ABB O3EHa HENF315087R2 Multi-Function I/O Interface Module (Advant Controller 450 Distributed Process Interface Unit)
Product Description
The O3EHa HENF315087R2 is a high-performance multi-function I/O interface module specifically engineered for ABB’s Advant Controller 450 distributed control system (DCS). It acts as a critical intermediary between field-level devices (such as sensors, transducers, and actuators) and the central controller, enabling bidirectional data exchange to support real-time process monitoring and control. This module is widely deployed in industrial sectors including chemical processing, pulp and paper manufacturing, water treatment plants, and power generation facilities—for instance, in a municipal wastewater treatment plant, it coordinates the monitoring of influent flow rates (via magnetic flow meters) and the control of aeration blowers, ensuring optimal dissolved oxygen levels in bioreactors (maintained within 2-3mg/L).
Equipped with a versatile combination of 8 analog input channels, 4 analog output channels, 16 digital input channels, and 8 digital output channels, the module efficiently handles mixed signal types, eliminating the need for multiple single-function modules. This integration reduces control cabinet space by up to 30% compared to discrete I/O solutions. The analog inputs are highly flexible, supporting 4-20mA current loops, 0-10V DC voltage signals, thermocouples (Type J, K, T for temperature ranges of -210°C to 1260°C), and RTDs (Pt100, Pt1000 for precision temperature measurement). In a chemical reactor application, this allows the module to simultaneously monitor reactor temperature (via a Type K thermocouple), pressure (4-20mA from a pressure transmitter), and pH levels (0-10V from a pH analyzer), with 16-bit resolution ensuring that even small changes (e.g., a 0.1pH shift) are detected.
