LT-123 DMX Signal Amplifier
1. Product Parameter:
LT-123 is dedicated to amplify, distribute, and insulate the signal that comes from the lighting system equipment
when it is connected to the bus of DMX512 (or RS-485).
3.
2. Need to use the multiple signals expansion output control, increase DMX (485) signal amplifier to distribute
multi-channel control.
1. It's specially designed for signal shaping amplification for DMX512 (485) signal which attenuated after a
long-distance transmission, realize extending the signal transmission distance;
1 channel input, 3 channels distributed output, there is a independently photoelectricity insulation of >3KV
between input and output terminals, and output terminals among 3 channels, so as to avoid the expensive
equipment such as light, 485 communications equipment, DMX driver, precise digital lighting controller,
being burnt by the possible high voltage which caused from the wrong wire connection and a broken
equipment, also can avoid the signal interference between each DMX equipment, to assure it works safely.
DMX (485) signal amplifier can isolate, amplify and distribute the signal to all kinds of DMX (485) control
equipment, see the example for the DMX Lighting.

1. 经远距离传输或者并接多个设备后, 对DMX（485）衰减的信号进行整形放大处理, 具有延长信号
传输距离的作用;
2. 需要用到多路信号扩容分支输出控制, 增加DMX（485）信号放大器分配多路控制;
3. 1路输入, 3路分配输出, 输入输出端之间, 3路输出端之间均独立光电隔离>3KV, 因此可以避免因接
错线或者某个设备出现故障时可能产生的高电压烧毁灯具、485通信设备、DMX驱动器、精密
数字式灯光控制台等贵重设备, 也同时避免不同的DMX (485) 设备之间信号干扰的作用, 确保其
安全运行。
