LC-103: Modbus Module with one AC input channel and 3 Relay output channels for light control

The LC-103 module is a light control module that does not require special skills to install and use. No special software is needed to control the outputs.

The LC-103 module provides one digital input channel (isolated via photocoupler) and 3 relay output channels. All output channels are form A relays, while the digital input channel is sink type. The input channel can control up to 3 relay channels with ON and OFF sequences without requiring a host controller. 4 kV ESD protection and 5000 Vrms isolation are also provided within the module.

When communication is required, the LC-103 is programmable with Modbus RTU commands, and the address is settable via an external DIP switch.

Ideal solution for centralized control of lamp systems via MODBUS line.
