RS-485 Active Hub with power supply function
The LC-485 is a 4-ch RS-485 active star wiring hub with power supply function. It has 4 independent RS-485 output channels and one RS-485 input channel. Each output channel is equipped with an individual driver. The data from a master to the input channel will simultaneously be forwarded to all the four output channels, and can supply power. The total power c***umption of the LC-485 device plus all devices on the four output channels must be less than the power of the input power supply, and the total c***umption of all devices on the four output channels must be less than 1 A. The power c***umpti*** of the LC/SC series modules for 24 V and 12 V currents are shown in the list. |

RS-485 Short-Circuit protection
The Short-circuit protection can automatically shut off the breakdown channel, this kind of design can suffice to protect the communication system. When connected RS-485 equipment breaks down, the breakdown channel will be isolated to ensure that other equipments work normally. |
