NJS3 series time relay is to connect or disconnect the circuit according to the preset time. It is mainly used in control circuits with a frequency of 50Hz and a rated control voltage of up to 220V as a time control element
The NJS3 series time relays are designed for AC 50 Hz control circuits with a rated control voltage up to 220 V. They function as timing elements that connect or disconnect the circuit after a preset interval, offering interval, break, and power‑on delay modes.
The manual lists technical parameters such as rated voltage, contact ratings, power consumption, reset time, and delay range, and includes wiring diagrams for 3‑wire and 4‑wire installations as well as physical dimensions for DIN‑rail mounting. This manual is written in Chinese.
| Rated control voltage | AC 220 V (up to 380 V) |
|---|---|
| Contact rating | AC‑15 220 V/3 A, 380 V/1.9 A; DC‑13 24 V/1 A |
| Power consumption | 3 VA |
| Reset time | < 1 s |
| Installation type | DIN‑rail (导轨式) |
| Delay range | 0.5 min ~ 20 min |
| Operating temperature range | -5 °C ~ +40 °C |
The relay is rated for AC 220 V (and up to 380 V) control voltage.
It provides interval delay, break (off) delay, and power‑on (on) delay modes.
The relay is mounted on a DIN rail (导轨式) using a TH35‑7.5 steel mounting rail.
The reset time is less than 1 second.
