DMX512 Amplifier & Splitter — DMX121 (1CH) / DMX124 (4CH, 4 Output Ports) Signal Repeater, AC100V-240V

Designed for DMX512 signal handling, this unit provides shaping/amplification and four-way distribution to restore weakened signals after long-distance transmission. Every input and output uses photoelectric high-voltage isolation, ensuring complete electrical separation for reliable DMX processing. Isolation is provided both between distribution output ports and between the input and output ports, preventing interference from control-line faults and protecting the digital lighting console. By maintaining clean, amplified signals to connected fixtures, the device increases the overall dependability of a DMX512 lighting control system. The DMX124 signal distributor belongs to the signal distributor family and is specifically built for DMX512 digital lighting control applications.
