The ABB DSAO 120 with part number 57120001-EY is an 8-channel analog output module designed for use in industrial automation systems. This module is capable of converting digital signals from a control system into analog voltage or current signals, which can then be used to control various industrial devices such as valves, motors, or other equipment.
Key Features：
Number of Channels: The DSAO120 module features 8 independent analog output channels, enabling simultaneous control of multiple devices.
Analog Output Type: It outputs voltage or current signals, with the typical range for industrial applications being ±10V or ±20mA. However, it's recommended to confirm the exact output range through ABB documentation.
Resolution: Offers a resolution of 0.05%, which is achieved through a 12-bit depth including the sign bit, ensuring precise control over the analog output.
Isolation: Some analog output modules offer electrical isolation between the input and output sides to enhance signal integrity and reduce noise. Verification of whether the DSAO120 provides isolation would require checking with ABB resources.
Industrial Process Control: Precise control of valves, motors, or other equipment based on sensor readings or control commands.
Factory Automation: Controlling conveyor speeds, motor operation, or other analog control needs.
Building Automation Systems: Regulating temperature, lighting, or other variables using analog signals.
The DSAO120 supports 8 channels with a voltage range of 2 +/-10V and a current range of +/-20mA, offering a resolution of 0.05% with 12-bit depth including sign bit.
