Product details

Overview

The SR3B261BD is a Schneider Zelio Logic smart relay with 22 I/O: 16 digital inputs conforming to EN/IEC 61131-2 Type 1, 6 analog inputs (0-10 V, 39 mV LSB), and 10 relay outputs rated for 500,000 cycles at 230 V AC-12 (1.5 A) and 24 V DC-12 (1.5 A). It includes a real-time clock with a drift of 6 s/month at 25 °C, a 90 ms scan time, and draws 4 mA from a 24 V DC supply.

Compared to the SR3B261JD, which has 12 digital and 6 analog inputs (18 total), the SR3B261BD adds 4 more digital inputs (16 vs 12) while keeping the same 6 analog channels, making it the higher-density choice for applications needing more discrete sensing.

The SR3B261BD is in active production; lead time is typically quoted per RFQ and varies by quantity.
