It carries a real-time clock that runs on supercapacitor backup for 10 years at 25 °C, with typical drift of 6 seconds per month at that temperature. The local display and program memory check on every power-up are built in, so you get immediate status at startup without a separate programmer. Cycle time is listed as 6…90 ms — that range covers simple to moderately complex ladder (up to 240 lines) or function block (up to 500 lines) programs, per the spec. The relay output response is 10 ms on-to-off and 5 ms off-to-on; for time-critical valve or contactor sequences, keep this in mind. Discrete inputs are 12 V DC, resistive type, with 4 mA draw per channel. Counting frequency on those inputs goes to 1 kHz, so it handles encoder or flowmeter pulses without a separate counter. The power budget sits at 3 W without expansion modules and 5 W with them; maximum supply current is 250 mA without expansion, 400 mA with — that gives you a headroom number when sizing the 12 V supply. Reverse polarity protection is included, saving a replacement if a field wire is crossed. EMC compliance covers IEC 61000-6-2 (industrial immunity), IEC 61000-6-3 and -6-4 (emission limits), and IEC 61131-2 Zone B. The conducted and radiated emission class is B per EN 55022-11 Group 1, so it is acceptable for both residential and industrial environments without external filtering in most panels. ## Build and mounting IP40 on the front panel, IP20 on the terminals — standard for a panel-mount smart relay. Screw terminals accept 0.2…2.5 mm² solid or stranded with ferrules, or 2 x 0.2…1.5 mm² solid. Tightening torque is 0.5 N·m. Clock drift is listed as 12 minutes per year over the full 0…55 °C range, but only 6 seconds per month at 25 °C — the drift is temperature-sensitive, so if your logic relies on precision time-of-day events in a hot cabinet, account for that. ## Sourcing note As an active catalog item from Schneider, the SR3B261JD is available to order. Submit an RFQ with your quantity and preferred lead time; no surplus or broker channel needed. This is a straight BOM line item for a new panel or a running replacement.","metaTitle":"Schneider SR3B261JD Zelio Logic Smart Relay, 12V DC, Real-Ti","metaDescription":"Active production modular smart relay with 16 discrete inputs, relay outputs, real-time clock, and program memory check on power-up.
