The LC-103 module is a module for lights control that not requires particular skills to be installed and used.Is not required any particular software to control outputs.
 
LC-103 module provides a digital input channel (isolated through photocoupler) and 3 outputs channels with relay. All outputs channels are relay of form A type, while the digital input channel is of sink type. The input channel can control up to 3 relay channels with ON and OFF sequences without requiring a host controller. Is supplied also a 4 kV ESD protection and an 5000 Vrms isolation inside the module.
 
When is required the communication, the LC-103 is programmable with Modbus RTU commands and the address is settable via external dip.

Ideal solution to achieve centralized controls of lamp systems through MODBUS line.
