Product Features

Digital Output Control: The primary function of the ABB SDA338AE chip is digital output control. These devices can be controlled by creating digital signals from commands received from a connected controller or automation system. This allows components such as motors, valves, and conveyors to be activated or deactivated in industrial processes.

Fault Detection and Isolation: Integrated into the module, the FDI checks for short circuit and overcurrent conditions, and it can check if an output channel is experiencing an abnormal condition persistently. If a fault occurs, the power supply is able to quickly disable the high voltage connection to the channel to avoid damage to the module or any equipment it may be connected to. It can also send a diagnostic message to the operator or connected control device indicating the location and cause of the fault for easier and faster troubleshooting and maintenance.

Configuration and programming flexibility: ABB SDA338AE software or hardware configuration methods can be easily configured to meet the specific requirements of the application. First, it parameterizes the output mode, such as source or sink for temperature controllers, the default state of the output, etc., as well as the module addressing for the automation network. The module can be integrated into different industrial control architectures through programming and configuration.

Application Range

HMI, SCADA system: ABB SDA338AE is commonly used in human-machine interface (HMI) and supervisory control and data acquisition (SCADA) systems for monitoring and managing industrial processes. It is used to manage conveyor belts, robotic arms and other automated processes in assembly online. It also ensures fast IIoT (Industrial Internet of Things) applications for monitoring and controlling production equipment produce accurate and reliable digital output signals, thereby ensuring the efficient operation of the production process, thereby improving productivity and product quality.

Building automation: ABB SDA338AE is used to control lighting centrifugal systems, HVAC (heating, ventilation and air conditioning) systems and access control systems in building automation systems. In this way, it can regulate the on/off status of lighting and HVAC utilities based on motion sensor input or pre-specified timelines, and can allow access to restricted locations by acting on door locks. This makes use more energy-efficient, improves occupant comfort, and enhances building security.
