Key Features
1. Versatile I/O Configuration
With 10 I/O points (6 digital inputs and 4 relay outputs), the SR3B101BD is capable of controlling a wide range of devices and processes, including machinery, lighting, and other automation systems.
Digital inputs are used for signal acquisition, while relay outputs allow for switching and controlling electrical loads.
2. Integrated Real-Time Clock
The built-in real-time clock allows for time-based control, making it suitable for event scheduling, time delays, and periodic automation tasks.
The clock feature enables the relay to execute actions based on specific times, such as switching devices on or off at predefined intervals.
3. Clear and User-Friendly Display
The integrated display provides real-time system status and diagnostic information, making it easier to monitor operations and troubleshoot any issues.
The user-friendly interface allows for quick configuration and maintenance without requiring specialized knowledge.
4. Modular Design for Expansion
The modular design of the SR3B101BD enables easy integration with additional I/O modules, allowing users to expand the system as their needs grow.
DIN rail mounting makes the relay easy to install in control panels, providing space-saving advantages and flexibility in setup.
5. Easy Programming with Zelio Soft Software
The relay is programmed using the Zelio Soft software, which provides a simple graphical interface for configuring logic, timing, and control actions.
Drag-and-drop programming makes it easy for users to customize the relay’s operation based on specific control needs.
