DSTD108L 57160001-ABW ABB Connection Unit

The ABB DSTD108L is a connection unit that forms a vital link in industrial control architectures, particularly within ABB's distributed control systems (DCS) like the Advant OCS. Its core function is to provide an interface that safely and efficiently translates signals between different voltage levels and types.

Signal Interfacing: The unit is designed to bridge the gap between low-voltage DC control signals and higher-voltage AC/DC loads.

Load Handling Capabilities: The relays are specified to handle a load current of up to 3 A (maximum), with a minimum load current of 0.1 A at 24 V.

Application Versatility: Due to its robust relay outputs, it is broadly applicable in various industrial sectors, including manufacturing, process industries, power generation, and marine applications, wherever reliable signal conversion and isolation are required.

Actuator Control: Controlling various types of actuators, such as pneumatic or hydraulic valve solenoids, dampers, or louvers, where the actuator requires a higher voltage or current than the control system can directly provide.

Interposing Relays for Safety Circuits: While not a dedicated safety relay, it can be used in general industrial safety applications to provide isolation and amplification for signals that trigger emergency shutdowns or interlocks, ensuring that control signals are robust enough to activate safety devices.

Building Automation and HVAC: In larger commercial or industrial buildings, it can be used to control pumps, fans, lighting circuits, or other building services based on signals from building management systems (BMS).
