1. Isolation performance,
electrical isolation of inputs and outputs completely realized.
2. Signal is transmitted, the
output signal on the input side without feedback,it could effectively stop lamp
circuit, lamp power supply ripple on the controller port of the disturbance, but it does not
cut off their signal transmission between.
3. Optical signal is not
affected by electromagnetic interference, stable and reliable.
4. Common-mode interference
resistance ability, can effectively suppress interference.
5. Optocoupler fast response,
high transmission efficiency.
TTL-SPI
Amplifier:
Hardware
parameter
1. Supply voltage: DC12-24V (RT
open circuit)/DC5V (RT short circuit).
2. Transmission distance:
controller to the received TTL optical isolation distances of up to 200 m.
4. Signal output: GND (ground
output terminal) DAT (data signal output terminal) CLK (clock signal output).
Notice:
A. controller to the TTL
signal output port to TTL photoelectric panels, a distance of 200 metres, if distance is more
than 200 meters, please test.
B. TTL opto-isolated sink
must be connected to the light side (close to the RGB LED pixel light input side), distance
no more than 5 meters.
C. RT when open, TTL
photovoltaic panels to power 12-24V, RT short-circuit, 5V power supply.(usually,when you order our
12V amusement LED pixel along with the Amplifier,we'll make it 12V, and when you get the
WS2812b addressable strip LED, we produce this amplifier as DC5V, then pls dont try to
burn it by 12V).
D. Prohibition of live-line
operation, prior to installation, please switch off the power supply. Please be waterproof,
moisture-proof.
