DX-30 series signal relay includes DX-31, DX-31A, DX-31B, DX-32A, DX-32B three varieties, suitable for direct current operation protection circuit As an action indicator.
The DX-30 series signal relays include five variants (DX-31, DX-31A, DX-31B, DX-32A, DX-32B) designed for DC protection circuits and act as operation indicators. The manual describes each variant’s function, such as voltage‑or‑current actuation, lamp or drop‑out signals, and the presence of normally‑open contacts.
Technical data cover coil voltage/current ratings, holding circuit voltages, contact capacities, dielectric strength, and life expectancy. Wiring diagrams for rear and front connections are provided, along with installation conditions, environmental limits, and ordering information. This manual is written in Chinese.
