The ICP DAS LC-103H is an easy-to-use lighting control module that requires no specialist skills to install and operate, and no software is needed in order to control the DO channels.

The LC-103H has a single channel for digital input (photo couple isolation) and 3 channels for relay output. All output channels are form A type relays, while the input channel is based on a sink-type using a wire connection. The input channel can directly control a 3-channel relay ON and OFF sequence without requiring a remote host controller. 4 kV ESD protection and 5000 Vrms intra-module isolation are also provided.

When required, communication with the ICP DAS LC-103H is programmable based on the DCON & Modbus RTU protocol, and an added benefit is that different addresses can be set for DCON & Modbus RTU communication via hardware configuration.
