PLCs, Power Supplies & Others

The Schneider AS875111 analog input module captures eight precision process signals. This unit weighs 0.38 kg and measures 12.0 cm x 8.5 cm x 4.5 cm. It provides 8 analog input channels for the Advantys system. The module contains one 16-bit ADC and eight conditioning circuits. For energy storage, it includes one 220µF tantalum capacitor. Therefore, the Schneider AS875111 maintains input stability during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the Schneider AS875111. Use this data for your system integration planning.

Analog Input Features

Each of the eight channels accepts either voltage or current signals. The Schneider AS875111 allows you to configure each input independently. Therefore, you can mix different sensor types on the same module. The 16-bit ADC delivers high resolution for precision measurements. Consequently, this module suits demanding process control applications perfectly.

Signal Conversion Performance

The conversion time reaches just 2 milliseconds for each active channel. Thus, the module scans all eight inputs within 16 milliseconds. The overall accuracy stays within ±0.1% of the full scale. Hence, the Schneider AS875111 provides extremely reliable measurement data. The resolution reaches 0.3 mV for voltage mode. For current mode, it achieves 0.6 µA per bit.

Power and Energy Storage

The Schneider AS875111 draws 90 mA from a 24V DC supply. Hence, its total power consumption equals 2.16W. The 220µF tantalum capacitor provides 10 milliseconds of hold-up time. This short backup protects input values during minor voltage sags. Furthermore, the module includes reverse polarity and overvoltage protection.

Installation and Connectivity

You can mount the Schneider AS875111 on a standard DIN rail. The module snaps directly onto the rail without special tools. The two 10-pin removable terminal blocks accept wire sizes from 0.2 mm² to 1.5 mm². For voltage signals, use twisted-pair cables with one wire grounded. For current loops, a simple two-wire cable works perfectly. The Schneider AS875111 works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This analog input module operates reliably from -10°C to +60°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the Schneider AS875111 suits harsh industrial environments perfectly.
