PLCs, Power Supplies & Others

The Schneider ASB875101 analog input module captures four precision process signals. This unit weighs 0.32 kg and measures 12.0 cm x 8.0 cm x 4.5 cm. It provides 4 analog input channels for the Advantys system. The module contains one 12-bit ADC and four conditioning circuits. For energy storage, it includes one 100µF tantalum capacitor. Therefore, the Schneider ASB875101 maintains input stability during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the Schneider ASB875101. Use this data for your system integration planning.

Analog Input Features

Each of the four channels accepts either voltage or current signals. The Schneider ASB875101 allows you to configure each input independently. Therefore, you can mix sensor types on the same module. The 12-bit ADC delivers sufficient resolution for most industrial applications. Consequently, this module suits process monitoring and basic control tasks perfectly.

Signal Conversion Performance

The conversion time reaches 5 milliseconds for each active channel. Thus, the module scans all four inputs within 20 milliseconds. The overall accuracy stays within ±0.5% of the full scale. Hence, the Schneider ASB875101 provides reliable and repeatable measurements. The resolution reaches 2.44 mV for voltage mode. For current mode, it achieves 4.88 µA per bit.

Power and Energy Storage

The Schneider ASB875101 draws 60 mA from a 24V DC supply. Hence, its total power consumption equals 1.44W. The 100µF tantalum capacitor provides 8 milliseconds of hold-up time. This short backup protects input values during minor voltage sags. Furthermore, the module includes reverse polarity protection on its power input.

Installation and Connectivity

You can mount the Schneider ASB875101 on a standard DIN rail. The module snaps directly onto the rail without special tools. The 10-pin removable terminal block accepts 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 ASB875101 works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This analog input module operates reliably from 0°C to +55°C. It also withstands 90% relative humidity without condensation. The module survives vibration up to 1.5g from 10 to 150 Hz. Therefore, the Schneider ASB875101 suits most industrial automation systems perfectly.
