Schneider SR2B121FU | compact smart relay Zelio Logic – 12 I O – 100.240 V AC – clock – display

 Specifications:

  • Model: SR2B121FU

  • Series: Zelio Logic – Smart Relay

  • Power Supply: 100–240 V AC

  • I/O Configuration:

    • 8 Digital Inputs

    • 4 Relay Outputs

    • 12 Total I/O Points

  • Output Type: Relay (normally open contacts)

  • Display: Integrated LCD screen with navigation keys

  • Clock: Built-in real-time clock (RTC)

  • Programming Interface: Via front panel or PC (USB/serial)

  • Mounting: DIN rail or panel mount

  • Programming Software: Zelio Soft 2 (supports Ladder and FBD)

 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)
