SR3B261FU Schneider Zelio Logic Smart Relay 26 I/O
Model: SR3B261FU
Brand: Schneider Electric
Series: Zelio Logic
The SR3B261FU is a modular smart relay from the Schneider Zelio Logic range. It packs 26 I/O points into a compact DIN rail housing. The controller runs on 100-240 V AC supply. It includes 16 digital inputs, with 6 configurable as analog. It offers 10 relay outputs rated 5 A each. An integrated real-time clock handles time-based logic. The LCD screen and navigation buttons allow on-site programming and monitoring. This relay suits small automation tasks that replace traditional relay panels.

FAQ
Q: Can the SR3B261FU replace a small PLC?
A: Yes, for logic, timing, and relay tasks. It lacks advanced motion control. Choose a PLC when you need high-speed counters or PID loops.
Q: How do I program this smart relay?
A: Use the built-in LCD and buttons for simple edits. For full programs, use Zelio Soft with ladder or FBD. The 240-line ladder memory covers most small jobs.
Q: What loads can the relay outputs drive?
A: Each output handles 5 A. They suit contactors, lamps, and small motors. Add interposing relays for high inrush loads. Check AC-12 ratings for inductive loads.
Q: Should I pick the SR3B261FU or a Zelio Logic with more I/O?
A: Count your inputs and outputs first. This model gives 26 I/O. If you need more points, step up the range or add extension modules. Analog needs may also push you to a larger unit.
Q: How do I verify a surplus or refurbished unit?
A: Ask for test reports and firmware version. Confirm the display and relay outputs work. Oiltech Controls checks each unit before shipment and backs it with a 12-month warranty.
