Expert Review
The SR3B261JD is a smart relay, not a full PLC. It suits small jobs where cost and space matter. The 26 I/O count covers many basic control tasks. The 12V DC supply works well in solar, vehicle, and remote sites. The LCD and buttons make on-site changes easy. The Zelio Logic software uses ladder or FBD, so techs learn it fast. The relay outputs handle 5 A, enough for small contactors and lamps. One limit: no built-in Ethernet. You need extension modules for communication. Overall, a strong pick for simple automation.
Manager’s Insight
Stock this SR3B261JD for customers who want Schneider quality without PLC cost. The Zelio Logic line moves fast in OEM and panel shops. The 12V DC version fits mobile and off-grid projects. The 26 I/O mix covers most small machine needs. The real-time clock adds scheduling without extra parts. Margins stay healthy because demand is steady. Keep spare relay outputs on hand for quick service.

Frequently Asked Questions
Q: Can the SR3B261JD run on 24V DC?
A: No. It needs 12V DC. The safe range is 10.4 to 14.4V. Use a 24V to 12V converter if needed.
Q: How many analog inputs does it have?
A: Six of the 16 digital inputs can work as analog inputs. That gives you flexible sensor options.
Q: What software programs this smart relay?
A: Use Schneider Zelio Soft software. It supports ladder and FBD. The free version covers this model.
Q: Can I expand the I/O later?
A: Yes. Add Zelio Logic extension modules. They clip onto the side of the relay.
Q: Does it come with a warranty?
A: Yes. We offer a 12-month warranty. Orders ship in 12 to 24 hours via FedEx, UPS, or DHL.
Q: What is the relay output rating?
A: Each relay output handles 5 A. The electrical life is 500,000 cycles at 230V 1.5A.
Q: Can I mount it outdoors?
A: Only inside a protected enclosure. The operating range is -20 to 55 °C. Keep it away from water and dust.
Q: Is a real-time clock included?
A: Yes. The built-in clock lets you schedule tasks by time and date. No extra module needed.
Buying Guide
- Check your supply: this model needs 12V DC, not 24V.
- Count your I/O needs. 26 points covers many small jobs.
- Need analog signals? You get 6 configurable inputs.
- Confirm relay output load. 5 A per output suits small loads.
- Plan for communication. Add extension modules if you need network links.
- Buy from a trusted source for genuine Schneider Electric quality.
