The D series solid state relay is a DC input and DC output type that can achieve DC level conversion, isolation and control, and can be easily interfaced with computers and various digital circuits. It is widely used in industrial automation fields to control various DC power executive devices, such as lighting equipment, small DC motors, DC power supplies, various electromagnetic devices and intelligent instruments, and can also be used as a driving level for various high-power output devices. Convenient to use, especially suitable for corrosive, humid and explosion-proof environments.
This manual describes the D series solid-state relays produced by BESTALL, focusing on DC input and DC output functions. The relays are suitable for industrial automation tasks such as lighting, small DC motors, power supplies, electromagnetic devices, and smart instruments, and can operate in harsh environments like corrosive, humid, or explosion‑proof settings.
Key topics include technical parameters, input and output control specifications, general characteristics, mounting options, and heat‑sink selection. Guidance is given for proper installation, thermal management, and safe operation under various load conditions. This manual is written in Chinese.
| Rated control voltage | 220 Vdc |
