Designed by Schneider Electric, the AS-B873-001 is an analog input module that is part of the Modicon 800 family. This unit allows for the connection of four input channels, which can handle a signal range of either 1 to 5 VDC or 4 to 20 mA. Input impedance values are specified at 1 MΩ when in voltage mode and 250 Ω for current mode, promoting flexibility in measurement applications.

The module is built with a resolution of 12 bits, ensuring that readings are both accurate and detailed. Its accuracy rating is measured at 7 mV, guaranteeing reliable performance across various applications. This device maintains a linearity rating of ±0.05% of the full scale at a temperature of 25°C, enhancing its precision in operational conditions.

An important characteristic includes the 400 ms update time for all four channels, allowing for relatively quick data acquisition. Safety features include channel-to-channel isolation rated at 250 VAC continuous and channel-to-module isolation at 300 VAC continuous, which helps to ensure signal integrity and device protection against electrical disturbances.

Power requirements for the AS-B873-001 includes 5 V at 300 mA, a +4.3 V input at 300 mA, and -5 V at 0 mA. Weighing 1.59 kg (or 3.5 lbs.), this analog input module is suitable for various applications while maintaining essential electrical specifications to provide thorough and accurate data monitoring.
