1. Introduction 

The LC-305 is a 5-channel AC Load Current Measurement Module. LC-305 

is fully RoHS-compliant and has qualification for 4 kV ESD protection and 

2000 VDC intra-module isolation is also provided. When required, 

communication with the LC-305 is programmable based on the Modbus 

RTU protocol, and an added benefit is that different addresses can be set 

via hardware configuration. The module can measure the load current of 

each lamp to verify if the lamp is normal or failed; check if the bulb begins 

to fade and needs to be replaced; and see if there is carbon-buildup 

depositing on the relay contacts which may makes the relay become sticky.
