Schneider Electric Harmony Relay Series Solid State Relay, 3.5 A Load, PCB Mount, 24 V DC Load, 30 V DC Control SSL1D03BD

Schneider Electric SSL1D03BD is a Harmony Relay Series Solid State Relay designed for industrial and automation applications requiring reliable, silent switching of DC loads. This solid state relay supports a maximum load current of 3.5 A and a load voltage ranging up to 24 V DC. It accepts control voltages from 15 V to 30 V DC, making it suitable for a variety of control interface requirements.

Its compact slim profile with a total width of 6 mm including the socket allows efficient use of space within control cabinets and PCBs. The relay is designed with PCB terminals and Single Pole Single Throw (SPST) contact configuration for straightforward integration in electronic systems.

The SSL1D03BD relay offers excellent environmental resistance complying with CSA, UL, and CE standards. It is shock, vibration, and pollution resistant with IP67 rating, making it ideal for demanding industrial conditions.

The relay incorporates features such as zero voltage switching or random switching modes, enabling high switching frequency and minimizing electrical noise. It has a very low off-state leakage current of 0.001 mA and a capacitance of 1.5 pF to ensure efficient and clean operation.

This relay is suitable for applications in industrial automation, control systems, signal conditioning, and other environments where compact, reliable, and maintenance-free solid state switching is required. It supports mounting directly on PCBs or can be implemented using DIN rail socket mounts with screw or spring terminals.

The relay provides silent and reliable switching with no moving contacts. Designed for harsh industrial environments with IP67 shock, vibration, and pollution resistance. Compact slim form factor including socket width of 6 mm saves control cabinet space.

Control voltage range from 15 V to 30 V DC enables versatile interfacing. High switching frequency and zero voltage or random switching options available. Mounting directly on PCB or DIN rail with available sockets for flexibility.

Wide operating temperature range from -20°C to 80°C ensures robust performance. Off state leakage current as low as 0.001 mA reduces power loss.

Schneider Electric’s Harmony Relay SSL series represents an innovative solution to industrial control needs by combining compact size, modular design, and long life span. This product fits well within the solid state relays category of industrial relays and supports diverse industrial, laboratory, manufacturing, and automation use cases.
