Schneider ALU 130 | Analog Input PLC Module

The Schneider ALU 130 provides high-precision analog input capabilities for the Modicon M340 platform. This PLC module features 8 analog input channels for voltage or current signals. It accepts 0-10 V DC and 4-20 mA inputs for flexible sensor connectivity. Weighing only 0.21 kg, the Schneider ALU 130 fits into any standard M340 rack slot. Its dimensions measure 100 mm x 55 mm x 70 mm.

Input Specifications and Signal Ranges

The Schneider ALU 130 offers 16-bit resolution for accurate measurement of analog signals. Each channel handles 0-10 V, ±10 V, 0-20 mA, or 4-20 mA inputs independently. The module provides a conversion time of only 1 ms per channel for fast response. Moreover, the Schneider ALU 130 includes built-in scaling from raw values to engineering units. Consequently, you can read pressure, temperature, or flow data directly in real-world units.

Energy Storage and Internal Components

The Schneider ALU 130 contains no internal battery for maintenance-free operation. It stores configuration data in non-volatile memory instead of relying on battery backup. This module draws 170 mA from the 5 V DC rack power supply. Additionally, it consumes 40 mA from the external 24 V DC field power supply. The Schneider ALU 130 includes 8 analog-to-digital converters for simultaneous signal processing. Therefore, it provides excellent channel-to-channel isolation and noise rejection.

Installation and Application Details

The Schneider ALU 130 mounts directly into any Modicon M340 rack slot. This module requires an external 24 V DC power supply for analog circuit operation. Use shielded twisted pair cables for all analog signal wiring to minimize noise. Connect the cable shield to the functional ground terminal at the module end. The Schneider ALU 130 suits process control, HVAC monitoring, and machine automation tasks. It handles temperature sensors, pressure transmitters, and flow meters perfectly. Thus, this analog input module delivers precise measurement for demanding industrial applications.
