ABB DSTA 155 57120001-KD Connection Unit

ABB DSTA 155 57120001-KD Connection Unit is another model in the ABB analog connection unit series, similar to the DSTA 001 series. It is part of ABB's distributed control system (DCS) and automation products and is used to facilitate the integration of analog field devices with control systems.

It can support analog current (4-20 mA), voltage (0-10 V), and possibly other industry standard signal types. Multiple channels can be configured for each unit, depending on the application requirements. Input/output signals can be amplified, filtered, and scaled to be compatible with the control system. Signals are isolated to prevent electrical noise and surges. Typically DIN rail mounted for easy installation in a control cabinet.

The unit can convert and transmit different types of analog signals, so that effective data interaction can be achieved between the analog devices on site and the control system. It can convert the 4-20mA current signal or 0-10V voltage signal collected by the sensor into a digital signal that the system can recognize and process for further control and monitoring.

It can condition the input analog signal, including amplification, filtering and other operations, to improve the quality and stability of the signal, ensure the accuracy and reliability of the signal, and reduce the impact of signal interference and noise on the system.

It provides multiple analog signal input and output interfaces, which can connect multiple analog devices, such as temperature sensors, pressure sensors, flow meters, etc., to realize the monitoring and control of multiple physical quantities, facilitate the expansion and integration of the system, and meet the needs of different application scenarios.
