The Schneider SR2D101BD smart relay operates on a 24V DC supply, with safe voltage limits ranging from 19.2V to 30V, consuming just 100 mA without extensions. Its output supports both 24–250V AC and 5–30V DC relay switching, making it adaptable for resistive and inductive loads. The unit includes 4 relay outputs, each with an 8A output thermal current, built for high-cycle durability rated at 500,000 operations per IEC 60947-5-1 standards.
Featuring a cycle time of 6–90 ms and a counting frequency of 1 kHz, the SR2D101BD provides fast and accurate control. The discrete input voltage is 24V DC, compatible with 3-wire PNP proximity sensors. It offers input impedance values of 7.4 to 12 kΩ depending on the circuit, and supports both analog and digital modes. Built to perform in harsh conditions, it functions between -20°C to +55°C and at altitudes up to 2000 meters. With a net weight of 0.22 kg, reverse polarity protection, and compact screw terminals, this Zelio Logic Smart Relay ensures simplified installation and long-term performance in small-scale automation tasks.
The SR2D101BD Smart Relay is ideal for compact automation tasks like pump control, motor start-stop, gate logic, lighting control, and sequential operations in small machines. With its 10 I/O capacity and flexible input compatibility, it replaces traditional relay logic with programmable control, improving reliability and diagnostics.
It is a preferred choice for control panel integrators, machine manufacturers, and maintenance teams who need a quick and space-saving automation solution. For field technicians, its screw terminals, 24V DC operation, and compatibility with standard industrial sensors make it convenient and low-risk to deploy in real-world projects.
Backed by Schneider Electric’s legacy and part of the Zelio Logic family, the SR2D101BD offers a smart, cost-effective entry into programmable automation.
