VSB24STB 24VDC SPDT Sealed PCB Power Relay 16A Through-Hole Mount

The VSB24STB is a high-performance sealed PCB power relay designed for demanding switching applications in industrial controls, automation equipment, power management systems, appliances, and electronic control circuits. Combining robust switching capabilities with a compact footprint, this relay delivers reliable performance and long operational life in environments where durability and dependable operation are essential.

Featuring a Form 1C (SPDT - Single Pole Double Throw) contact configuration, the VSB24STB provides versatile switching functionality, allowing a single circuit to alternate between normally open and normally closed contacts. This makes it ideal for control systems, power distribution equipment, motor control circuits, HVAC systems, and general-purpose switching applications.

The relay operates from a 24VDC coil and incorporates a 1.1k coil resistance, drawing approximately 21.82mA while consuming only 530mW of power. This efficient coil design ensures reliable actuation with low energy consumption, making it suitable for continuous operation in automated systems.

Designed for high-current applications, the VSB24STB supports switching currents up to 16A and can handle voltages up to 380VAC or 150VDC. Its silver alloy contacts provide excellent conductivity, low contact resistance, and reliable switching performance under both inductive and resistive loads.

The fully sealed construction protects the internal components from dust, moisture, contaminants, and cleaning processes, improving reliability and extending service life in harsh operating environments. This makes the relay particularly suitable for industrial equipment, outdoor control systems, and applications exposed to challenging environmental conditions.

With a through-hole PCB mounting design and standard PC pin termination, installation is straightforward and secure. Its compact dimensions allow efficient use of board space while maintaining excellent electrical performance.

Engineered for durability, the relay operates across a wide temperature range from -40 C to +75 C and features a fast operating time of approximately 15ms, ensuring responsive and dependable switching performance.
