Description
The ABB DSTD 108L is a connection unit module used in the ABB S100 I/O system. It serves as an interface between the S100 I/O modules and external devices, providing eight powerful 24-250 VAC/DC relays for switching and control applications.
Key Features:
- 8 Relay Outputs: The DSTD 108L offers eight independent relay outputs, enabling control of various devices like lights, motors, valves, and solenoids.
- High Switching Capacity: Each relay output can handle up to 200 mA switching current, suitable for most control applications.
- Wide Voltage Range: It supports a wide input voltage range of 24-250 VAC/DC, making it compatible with various power sources.
- Compact Design: Its compact size makes it easy to integrate into space-constrained control panels.
- DIN Rail Mounting: It features DIN rail mounting compatibility for convenient installation in control cabinets.
Function:
The DSTD 108L acts as a bridge between the S100 I/O modules, which receive control signals from a PLC or other control system, and the external devices that need to be controlled. The S100 I/O modules send their signals to the DSTD 108L, which then activates the corresponding relays based on the received signals. The activated relays provide the necessary electrical currents to switch or control the connected devices.
Applications:
The DSTD 108L finds application in a variety of industrial automation settings, including:
- Machine Control: Controlling motors, actuators, and other components in machinery and automation systems.
- Process Control: Regulating valves, pumps, and other elements in industrial process control systems.
- Lighting Control: Switching lights, signs, and other lighting fixtures in industrial and commercial environments.
- Alarm Systems: Activating alarms, warning lights, and sirens in safety and monitoring applications.
