FEATURES
DC Switching
Reliable switching is achieved using semiconductor devices. It can be used easily as a Solid State Relay (SSR).
Breaking Capacity
SCSR Series: DC 143 V, 3 A
High-Speed Response
Operating and release times are significantly faster than those of mechanical relays. In addition to resistive loads, it can also be used for high-speed switching of inductive loads such as DC solenoids when used together with a protection device.
Long Service Life
Since there is no contact wear caused by arcing, the relay offers excellent switching durability. It helps reduce maintenance and replacement work in applications requiring frequent switching, such as brake circuits.
Remote Control
The control signal uses DC 24 V, which can be driven by PLC signals and other control systems, allowing easy remote operation.
Silent Operation
Since semiconductor devices are used for the main switching circuit, the relay operates silently, making it ideal for nighttime operation and noise-sensitive environments.
High Reliability
The contactless design eliminates problems such as contact oxidation and contamination, ensuring high reliability.
Overcurrent Protection
If the rated current is exceeded due to an abnormal load or power supply condition, the main circuit is automatically shut down to protect the equipment from damage. (STH Series only)
Electric Power Standard (B-402)
Designed for power relay applications, it provides excellent reliability in terms of noise immunity, voltage fluctuation tolerance, insulation performance, and other electrical characteristics.
