Basic Parameters of Intelligent Relay Modules
- Functions: supports start and stop of lamps, light switches, blinds control, and delayed start of multiple circuits (to avoid network interference).
- Intelligent interconnection: Through Pyxos bus interface, it can be connected with intelligent control system; module failure will not affect the bus connection.
- Maintenance concept: Plug and Play, “guaranteed” maintenance support.
- Parameters
- Power consumption: 180 mA @ 12V
- Operating temperature: -10℃~50
- Relay load: 250VAC/16A ( optional model 20A)
- COM port baud rate: 1200~115200 bps
- Model Selection
- 4 way: CW.RY040416 (16A), CW.RY040420-A (20A)
- 8-way: CW.RY080816 (16A), CW.RY080820-A (20A)
- All support manual operation and current sensing (optional)
The relay module is suitable for a wide range of applications, enabling device start/stop, light switching and blinds control. Through the Pyxos interface it can be connected to intelligent control systems.
Easy to maintain: “Guaranteed” maintenance, plug and play.
High reliability: single chip control, modules communicate with each other via the Pyxos bus, damage to intermediate modules will not cause the entire bus to fail.
Delayed start : with multi-loop delayed start function, avoiding the impact of synchronized start on the power grid.
