Information About SR3B261BD
The SR3B261BD is part of the Schneider Electric Zelio Logic SR2/SR3 smart relay family, intended for small to medium-scale automation applications. It combines discrete and analog inputs with relay outputs in a single compact housing, using screw-clamp terminals for secure field wiring. The unit integrates easily into control panels via DIN rail mounting and supports function block diagram programming for straightforward configuration. It is commonly used in machine control, building automation, pumping systems, and auxiliary process control where compact logic control and local visualization are required.
Key Features:
- Zelio Logic SR3 series platform: Designed for compact industrial automation tasks.
- 24 VDC supply operation: Compatible with standard industrial DC control power.
- Integrated local display: Enables on-device monitoring and parameter visualization.
- Combined digital and analog inputs: Supports mixed-signal control applications.
- Relay output configuration: Provides reliable switching for AC and DC loads.
- Built-in real-time clock: Enables scheduling and time-based control logic.
- Long program memory retention: Maintains application data without external power.
- Screw-clamp terminals: Ensures secure and vibration-resistant wiring connections.
- DIN rail mountable design: Simplifies installation in control cabinets.
The SR3B261BD delivers the reliability and precision required for compact logic control and automation in industrial environments.
