JSZ4 series time relay is a multi-function relay with a combination of delay time A, B, C, D, E, F. It has the function of power-on delay or power-on delay with flashing. It can be used to control the start and stop of various mechanical or electrical equipment.
This manual describes the JSZ4 time relay family, including the YA and NA models. It outlines the device's functions, time‑setting ranges, and electrical ratings, and provides guidance for proper installation and wiring.
Key features include selectable installation types (device‑mounted or panel‑mounted), multiple time‑setting groups, a wide input voltage range, and a delay accuracy of ±10 %. The document also lists physical dimensions and environmental limits for reliable operation. This manual is written in Chinese.
