ICP DAS Dimmer Control Module
- Product Code:
The LC-221 is an easy-to-use dimming ballast control module that requires no specialist skills to install and operate. It provides two methods of controlling the brightness of fluorescent lamps via a dimmer, either via digital input or a host controller. The digital input can directly control the light value from 10% to 100% luminous fl ux in sequence, without requiring a remote host controller. 4 kV ESD protection and 2500 VDC intra-module isolation are also provided. When required, communication with the LC-221 is programmable based on the Modbus RTU protocol, and an added benefit is that different addresses can be set for Modbus RTU communication via hardware configuration.
