 Key Features:

1. All-in-One Compact Controller

   • Combines control logic, scheduling, and monitoring in a single, space-saving unit—perfect for standalone or small-scale automation systems.

2. 12 I/O Channels

   • 8 inputs for sensors, switches, or contact signals.

   • 4 relay outputs to control loads like lights, motors, and valves (rated for switching up to 8A).

3. Integrated LCD Display

   • Built-in screen shows status, diagnostics, and allows manual operation. Enables local setup and testing without external devices.

4. Real-Time Clock

   • The internal RTC allows for scheduled operations, such as timed lighting, pump control, or heating systems.

5. User-Friendly Programming

   • Use Zelio Soft 2 for intuitive programming with ladder diagrams or function block diagrams. Also programmable from the front panel for quick changes.

6. AC Powered (100–240V)

   • Operates directly from standard AC supply—no need for external power converters.

7. Expandable & Modular

   • Can be expanded with additional I/O modules if your application grows, ensuring long-term flexibility.

8. Reliable Relay Outputs

   • Relay contacts ensure safe switching of both resistive and inductive AC loads, offering reliable performance in automation scenarios.

 Applications:

• Lighting Automation (e.g. store displays, timed exterior lights)

• Irrigation Systems (e.g. garden or agricultural automation)

• Access Control (e.g. timed gate or door opening)

• HVAC Scheduling (fan, heater, or AC control by time)

• Small Machine Control (e.g. conveyors, feeders, mixers)

• Energy Management (e.g. time-based device shutdown/startup)
