Product Overview
The AC2402 provides two analogue inputs for 4–20 mA signal acquisition. It supports 2-wire and 3-wire sensor connections. Measured values are converted and transmitted through the AS-i network. The CompactLine design provides distributed measurement acquisition close to the process. Its IP67-oriented field construction supports industrial environments.
Analogue Signal Processing
The module receives standardized 4–20 mA process signals. It converts the analogue signal into digital AS-i process data. This allows PLC systems to process measurement values without separate analogue I/O cards at every machine section. The module supports efficient decentralized measurement architecture. Its configuration is suitable for common industrial process sensors.
Installation & Integration
M12 connections simplify sensor installation. The compact module can be positioned close to measurement points. AS-i communication reduces long analogue signal cable runs. Distributed installation can improve signal integrity and simplify cabinet wiring. The module integrates directly with AS-i masters and PLC systems.
Diagnostics & Maintenance
The network architecture allows centralized module monitoring. Sensor signal availability can be checked through the controller. The robust field housing reduces exposure-related maintenance. M12 connections simplify sensor replacement. The module supports systematic troubleshooting of analogue channels.
