Schneider SR2B201BD Zelio Logic Smart Relay 20 I/O

Zelio Logic SR2B201BD 24V DC Compact Smart Relay from Schneider Electric

Product Introduction

The SR2B201BD belongs to the Schneider Electric Zelio Logic range of compact smart relays. This controller offers 20 I/O points in a space-saving design. Specifically, it provides 12 digital inputs and 8 relay outputs. The inputs follow IEC 61131-2 Type 1 specifications for 24V DC signals. Therefore, it interfaces directly with standard sensors and push buttons. Furthermore, the integrated real-time clock supports time-based control functions. Meanwhile, the LCD screen and navigation buttons simplify on-site programming. Additionally, the SR2B201BD runs on 24V DC and mounts on a 35mm DIN rail. As a result, it suits small machines, packaging equipment, and building automation.

Technical Specifications

The SR2B201BD delivers solid performance for small control systems. Its key ratings include:

• Number of I/O points: 20

• Digital inputs: 12 (24V DC, IEC 61131-2 Type 1)

• Digital outputs: 8 relay

• Relay output current: 5 A per output (10 A max per common)

• Supply voltage: 24V DC (19.2–30V)

• Clock: Integrated real-time clock

• Display: LCD with navigation buttons

• Program memory: 240 lines ladder / 500 blocks FBD

The relay outputs handle up to 5A each, with 10A maximum per common. Consequently, they drive contactors, solenoids, and indicator lamps directly. Besides, the 12 DC inputs accept signals from proximity sensors and limit switches. For instance, it works well in conveyor control, pump sequencing, and access control. Moreover, communication is possible through extension modules. Therefore, the relay can join larger control networks when needed.

Mechanical and Environmental Parameters

The SR2B201BD is built for industrial environments. First, its operating temperature range spans -20 to 55 °C. Next, the mechanical life of the relay output reaches 10,000,000 cycles. In addition, the electrical life reaches 500,000 cycles under AC-12 at 230V and 1.5A. The dimensions measure 90 × 107.6 × 59.5 mm (H×W×D). Meanwhile, the weight is about 0.28 kg. The housing uses durable thermoplastic material. Furthermore, the 35mm DIN rail mount allows quick installation. As a result, maintenance and replacement stay simple.

Installation Guide

Installing the SR2B201BD takes only a few steps. First, switch off the power supply and verify zero voltage. Next, clip the relay onto a 35mm DIN rail until it clicks. Then, connect the 24V DC supply to the dedicated terminals. Besides, wire the inputs and outputs according to your wiring diagram. Moreover, keep signal cables away from power cables to reduce noise. Finally, power up the unit and load your program via the LCD or software. However, always follow local electrical codes during wiring. Therefore, a qualified technician should perform the final commissioning.
