DIN-121 DIN Rail DMX Signal Amplifier DIN-121 DIN Rail DMX Signal Amplifier
DIN-121 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), 1CH input,
2CH output.

1.
1 channel input, 2 channels distributed output, there is photoelectricity insulation between
input and output terminals, 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.

1. Product Parameter:
2. Product Size:
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.
Need to use the multiple signals expansion output control, increase DMX (485) signal
amplifier to distribute multi-channel control.

*
An amplifier is needed when more than 32 decoders are connected, signal amplification should not be more than 5 times continuously.
* If the recoil effect occurs because of longer signal line or bad line quality , please try to connect 0.25W 90-120Ω terminal resistor at the end of each line.
