The AC2403 is a two-channel AS-Interface analogue input module for acquiring 4–20 mA signals from industrial sensors. It supports 2-wire and 4-wire sensor configurations and converts measurement signals into AS-i process data. The compact field-mounted design reduces analogue wiring distances. Its V4A construction is suitable for demanding industrial environments. It is ideal for decentralized process measurement and PLC integration.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
Product Overview
The AC2403 provides two analogue current inputs for industrial measurement signals. It supports 2-wire and 4-wire sensor arrangements. The module transfers measurement values through the AS-i communication system. Distributed installation allows the module to be positioned close to the process sensor. This architecture reduces the need for centralized analogue input wiring.
Signal Acquisition
The module receives standardized 4–20 mA signals. Digital conversion allows the PLC to process the values through the AS-i network. The two channels can be used for independent process measurements. The design is suitable for continuous process monitoring. It provides an efficient interface between field transmitters and automation controllers.
Installation & Integration
M12 connections provide convenient sensor wiring. The module is designed for field-level installation. AS-i networking provides a single communication infrastructure for distributed I/O. V4A construction supports applications where enhanced material resistance is beneficial. The module can be integrated into process skids and machine automation systems.
Diagnostics & Maintenance
Channel data can be monitored from the AS-i master. Sensor signal interruption can be identified through controller diagnostics. Standardized connections simplify maintenance. The compact design minimizes cabinet-side wiring. Field service can be performed without extensive panel rewiring.
