This document introduces the application scope, models and meanings, main parameters and technical performance, structural principles, and appearance and installation dimensions of the DX-30 series signal relays. This series of signal relays are suitable for use in DC-operated protective circuits as action indicators, with features such as voltage or current operation, jump board signal, mechanical hold, and hand reset.
The DX-30 series signal relay includes variants DX-31A, DX-31B, DX-32A and DX-32B. The manual describes the relay’s purpose, model variants, technical parameters, construction, and installation details.
Key sections cover rated voltage and contact ratings, power consumption, mechanical and electrical life, as well as physical dimensions and wiring options. This manual is written in Chinese.
