Industrial Applications

1. Interfacing 230V AC Machine Signals to Low-Voltage DC Control Systems

In industrial machinery, safety and control systems often operate at low DC voltages (e.g., 24 V DC), while sensors or actuators providing feedback may operate on 230 V AC. This solid-state relay acts as a robust interface, converting a 230 V AC input signal into a galvanically isolated DC output suitable for PLCs or other low-voltage control circuits. The 2.5 kV AC isolation protects sensitive electronics, and the compact 6.2mm width allows for dense panel integration.

Problem Solved

Safely and reliably interfaces high-voltage AC feedback signals from machinery (e.g., motor status, limit switches) with sensitive low-voltage DC control logic, preventing damage due to voltage mismatches and providing electrical isolation for safety.

2. Switching Low-Power DC Loads from 230V AC Building Management Systems

In modern building automation, central management systems often use 230V AC for control signals. This relay can take a 230V AC command (e.g., 'turn on light', 'activate fan') and safely switch a low-power DC load (e.g., 24 V DC LED driver, small DC fan motor, or a signal to a DC-controlled damper) with its 3-48V DC/100mA output. Its compact 6.2mm size allows for dense installations within control panels.

Problem Solved

Enables the integration of 230V AC building control signals with low-voltage DC loads or control circuits, providing reliable, wear-free switching for applications like intelligent lighting, fan control, or damper actuation, while maintaining electrical separation.

3. Process Control Signal Conditioning in Demanding Environments

In process industries, control panels need to accept signals from various field devices. If a field device provides a 230V AC status signal (e.g., pump running indication) but the central DCS/PLC requires a 24V DC input, this solid-state relay provides the necessary voltage conversion and critical 2.5 kV AC isolation. Its operating temperature range of -20 °C to 60 °C makes it suitable for typical industrial control cabinet environments.

Problem Solved

Provides reliable and isolated conversion of 230V AC process signals to 24V DC for PLC/DCS systems, ensuring signal integrity, protecting sensitive control electronics from voltage surges, and allowing operation in standard industrial temperature ranges.
