SSM1D26BD 6A DC Solid State DIN Rail Relay 4-32VDC Control Input

The SSM1D26BD Harmony Solid State Relay from Schneider Electric is a compact, high-performance DIN rail-mounted solid-state relay designed for reliable DC load switching in industrial automation, process control, machine building, and electrical control panel applications. Utilizing advanced MOSFET output technology, this relay delivers silent, maintenance-free operation with fast switching speeds and exceptional durability.

Designed for DC switching applications, the SSM1D26BD accepts a wide control input range of 4 to 32VDC, making it compatible with PLCs, microcontrollers, sensors, industrial controllers, and automation equipment. The output is rated for switching DC loads from 1VDC to 60VDC with a continuous current capacity of up to 6A, providing a versatile solution for controlling motors, solenoids, valves, actuators, lighting systems, and other DC-powered devices.

Unlike conventional electromechanical relays, the solid-state design contains no moving contacts, eliminating mechanical wear, contact bounce, and arcing. This results in significantly longer service life, increased reliability, and virtually silent operation, even in applications requiring frequent switching cycles.

The integrated heatsink enhances thermal performance and simplifies installation by eliminating the need for additional cooling components in many applications. Its slim 11mm-wide modular housing allows high-density mounting on standard DIN rails, helping maximize control panel space while maintaining efficient heat dissipation.

The relay features a built-in green LED status indicator that provides clear visual confirmation of input activation, simplifying system diagnostics and maintenance. Fast switching times of 0.6ms turn-on and 0.3ms turn-off make the SSM1D26BD suitable for precision control applications requiring rapid response.

Engineered for industrial environments, the relay offers 4kV dielectric isolation between input, output, and housing, ensuring excellent electrical protection and noise immunity. It complies with IEC standards and carries UL, CSA, and CE certifications, confirming its suitability for demanding industrial and commercial installations.
