DXM-2A signal relay is suitable for DC operating protection line and automatic control line for remote return action indication
The DXM-2A signal relay is designed for DC protection and automatic control circuits, featuring sealed contacts, operating and release windings, a self‑locking magnet and indicator lamp. The manual describes the internal wiring, external dimensions and proper installation.
Key sections include technical specifications (action current/voltage, release voltage, contact break capacity, electrical life), wiring instructions for terminals 1‑6 (operating) and 4‑9 (release), debugging methods, physical dimensions, and ordering information. This manual is written in Chinese.
| Action current start | 85% I_e |
|---|---|
| Voltage start | 70% U_e (220 V, 110 V, 48 V, 24 V) |
| Release voltage | 70% U_e (220 V, 110 V, 48 V, 24 V) |
| Contact break capacity | 220 V, 5×10⁻³ s, 10 W DC, 30 W resistive |
| Electrical life | 5000 operations |
| Operating temperature range | -25 °C to +40 °C |
| Maximum altitude | 2000 m |
| Maximum relative humidity | 90 % |
| Maximum installation tilt | 5° |
Terminals 1‑6 are for the operating winding (terminal 1 is “+”), and terminals 4‑9 are for the release winding (terminal 4 is “–”).
The relay is rated for 5 000 electrical operations.
A release voltage of 70 % of the rated voltage (U_e) – e.g., 220 V, 110 V, 48 V or 24 V – is required.
