Product Name:

Schneider SR3B101BD – Modular Smart Relay
Series: Zelio Logic SR2/SR3
I/O: 10 Inputs/Outputs
Power Supply: 24V DC
With Real-Time Clock (RTC) and Display
Outputs: 4 Relay Outputs

1. General Description:

The Schneider SR3B101BD is a modular smart relay from the Zelio Logic SR2/SR3 series, designed for small-scale automation applications. It combines programmability, real-time control, and an onboard display in a compact device that operates on 24V DC.

This model includes 10 total I/Os, a real-time clock (RTC) for time-based scheduling, and a clear LCD display for monitoring and manual interaction. It also includes 4 relay outputs for switching loads.

2. Key Features:

Feature	Description
Product Type	Modular programmable smart relay
Series	Zelio Logic – SR2/SR3
Model	SR3B101BD
Power Supply	24V DC
Inputs/Outputs	10 total I/O (typically 6 inputs, 4 outputs)
Output Type	4 relay outputs (mechanical switching)
Display	Built-in LCD – for real-time status and navigation
Clock Function	Includes RTC (Real-Time Clock) – for time/date-based operations
Programming Interface	Programmed via Zelio Soft software or front panel buttons
Mounting	DIN rail or panel mounting

3. Inputs & Outputs (Typical Configuration):

6 Digital Inputs:
Accept 24V DC signals (from sensors, push buttons, etc.)
4 Relay Outputs:
- Suitable for controlling lamps, contactors, relays, or small loads
- Each output can handle up to ~8A (check datasheet for exact value)

4. Main Functionalities:

Programmable Logic Control:
Can perform functions such as:
- Timers and counters
- Sequential control
- Pulse generation
- Delays and logic gates
- On/off cycles
Real-Time Clock (RTC):
Enables time- and date-based control (e.g., turning lights on at 6:00 PM and off at 10:00 PM).
On-Device Display:
LCD screen allows:
- Monitoring input/output status
- Viewing alarms or messages
- Navigating and adjusting parameters
- Manual control and diagnostics
User-Friendly Programming:
- Use Zelio Soft on a PC for graphical programming (ladder diagram or function blocks)
- Simple logic can be configured via onboard keys

5. Applications:

Perfect for simple to medium automation tasks like:

Lighting control systems
Pump and motor control
Irrigation systems
Access control
Building management systems
Small machines and conveyors

Ideal where PLCs would be overkill or cost-prohibitive.

6. Advantages:

Compact size, DIN rail mounting
24V DC operation – compatible with low-voltage control systems
Built-in clock for scheduled operations
Easy setup, even for non-experts
Expandable via Zelio Logic extensions if needed

7. Summary:

The Schneider SR3B101BD is a modular, programmable smart relay with 10 I/O, 24V DC power, 4 relay outputs, a real-time clock, and an LCD display. It’s designed for small automation systems needing flexible, time-based, and user-programmable control, making it ideal for both industrial and building applications.
