SCHNEIDER AS-BDAU-204 is an analog input/output(I/O)module manufactured by Schneider Electric.Here is a detailed introduction to it:

1.Basic Information

Brand:SCHNEIDER

Model:AS-BDAU-204

Type:Analog Input/Output(I/O)Module

2.Technical Specifications

Number of Channels:AS-BDAU-204 has four analog input/output channels.

Input Range:The module can accept analog input signals from various sensors,usually ranging from 0 to 400 ohms.

Output Function:The module can also output analog signals for controlling devices such as adjustable frequency drives,positioning valves,dampers,etc.

Resolution:In terms of analog input,AS-BDAU-204 can convert analog values​​into 12-bit digital values,providing high-resolution input signal processing.

Power requirements:The module requires an external power supply(such as 250mA 24VDC).When no external power is used,the module can obtain power from the internal bus,but may give erroneous readings.

Communication protocol:Supports multiple communication protocols for easy integration with other control systems.

III.Functional features

Analog signal processing:AS-BDAU-204 is able to perform dual slope integral A/D conversion to convert analog signals into digital signals for processing by PLC or other control systems.

Configuration flexibility:Each channel can be independently configured to provide voltage or current loop output to meet different control needs.

Fault diagnosis:The module has an open current loop(broken wire)detection function.When an open circuit or high loop impedance is detected,a warning will be issued through LEDs and accessible registers.

Hold function:AS-BDAU-204 can be configured to hold the last value when communication with the CPU is lost for more than a certain time(such as 1 second)to ensure system stability.

LED indication:There are amber and green LED indicators on the front of the module to indicate the status of the module and the activity of the channel.

4.Application Fields

AS-BDAU-204 is widely used in industrial automation,process control,monitoring systems and other fields.It can be used with various sensors and actuators to achieve precise control and monitoring of industrial processes.
