DSTD108
Main features and advantages:
The DSTD108 delivers reliable timing performance with its high-stability quartz oscillator ( ± 5 ppm accuracy over -20 ° C to+70 ° C), providing consistent timekeeping for most small and medium-sized enterprises industrial applications. While not offering the ultra-high precision of rubidium-based modules, it ensures sufficient accuracy for synchronizing basic equipment and control loops, with a timekeeping resolution of 1 microsecond that meets the needs of standard automation tasks. The module supports essential timing protocols including NTP and simple pulse synchronization, enabling basic coordination with other devices in the system.
Control functionality in the DSTD108 is focused on essential needs, featuring 16 configurable digital inputs, 16 digital outputs, and 8 analog input channels—all designed to interface with common industrial sensors and actuators. This I/O configuration provides enough capacity for small to medium systems without the complexity of higher-end modules. The module includes basic control algorithms such as simple PID control, event-based triggering, and timer-based sequencing, allowing for the implementation of standard automation logic without requiring advanced programming skills.
Hardware highlights include a compact, rugged design with an operating temperature range of -20°C to +70°C, ensuring reliable operation in typical industrial environments. The DSTD108 features basic electromagnetic compatibility (EMC) protection suitable for standard industrial settings, making it resistant to common electrical noise. It also includes essential diagnostic capabilities, with status indicators for power, synchronization, and I/O operation, enabling quick visual checks and basic troubleshooting. The module’s compact size makes it easy to install in crowded control cabinets, saving valuable space in smaller facilities.
Application areas:
In the diverse landscape of industrial automation, not all applications require the full capabilities of high-end timing and control modules. Many Small and medium-sized automation systems, such as regional manufacturing lines, local water treatment facilities, and small scale logistics centers, require reliable timing and control solutions that balance performance with cost-effectiveness. This is where DSTD108 comes into play, offering a compact, efficient solution tailored to meet the needs of these applications without unnecessary complexity
The DSTD108 is ideally suited for use in small to medium manufacturing workshops, where it synchronizes basic production equipment like conveyors, packaging machines, and simple robotic arms to ensure smooth operation. In local water and wastewater treatment plants, it coordinates pump operations, valve controls, and level monitoring systems, optimizing resource usage and ensuring compliance with local regulations. Small logistics hubs leverage it to synchronize inventory tracking systems, sorting equipment, and basic material handling devices, enhancing operational efficiency. By addressing the specific needs of smaller-scale operations—such as simplified installation, lower cost, and essential timing/control functionality—the DSTD108 delivers reliable performance for applications that don’t require the advanced capabilities of high-end modules.

Installation and maintenance:
Before installing the DSTD108, ensure the mounting location provides adequate ventilation with at least 20mm of clearance above and below the module to prevent heat buildup. Its compact size allows for installation in crowded control cabinets, but ensure there is enough space for wiring access to the terminal blocks.
When wiring the DSTD108, use standard industrial cables for all connections, with shielded cables recommended for analog signals and timing connections to minimize interference. Connect the power supply to a stable 24V DC source, and if backup power is required, ensure the secondary power input is properly configured. For network connections, use Cat5e or higher Ethernet cables for reliable communication. Configure basic parameters such as IP address, timing settings, and I/O configurations using the simplified web interface or manufacturer’s configuration software, which is designed for ease of use.
For maintenance of the DSTD108, perform monthly checks of status indicators to verify power, synchronization, and normal operation. Conduct quarterly visual inspections to ensure connections remain tight and free from corrosion. Calibrate analog inputs annually using basic calibration equipment to maintain measurement accuracy.
Firmware updates can be applied during scheduled maintenance periods using the manufacturer’s software tools. Before updating, back up current configurations to prevent data loss. Maintain simple records of maintenance activities and any configuration changes to support troubleshooting.
