AFL-160
Digital/Dry contact closure Fiber Optic Link |
|
Actual Size: TX:75 x 60 x 23mm, RX:115 x 90 x 23mm (box only)
Price starts from $925.- per pair (Transmitter and receiver units, TTL I/O), basic configuration, Multi-Mode. |
When you need to:
 Transfer Digital Control signals from a noisy environment,
Isolate digital signal from high voltage sources,
Control systems over a long distance,
Reduce wiring costs,
Get rid of interferences and spikes
Get fast and accurate response to your control signals,
The AFL-160 digital/Dry contact fiber optic link is the answer.
The AFL-160 was primarily designed for industrial and control application. The product is sampling the 16 Digital TTL input at a rate of 93 KHz. simultaneously and transmit all control signals to 16 digital outputs. Those outputs are available as 16 relays or as 16 TTL compatible outputs (0-5V). A "LINK" led and relay contacts enables the user to know if the link was disconnected and take any precautions needed to halt the system.
Input sampling and output updates may be synchronised to external circuits or controllers by using the "SAMPLE" pin at the Transmitter or at the Receiver.
The
AFL-160 consists of the following components:
A digital input Fiber Optic Transmitter - AFL-160/TX,
With TTL compatible inputs.
A digital Fiber Optic Fiber Optic Receiver - AFL-160/RX,
This unit can be configured with Dry contacts (1 change-over per TTL input)
Or with TTL outputs.
Up
to 3 km of of Multi-mode glass fiber or 50 Km of Single-mode fiber (optional).
Optical budget with Single Mode transceivers: 30 dB
2 power supplies of 12V - one for each side.
The link is connected between the TTL inputs at the transmitter , and the Relay contact outputs at the receiver. |

Advantages
Low
noise transfer of digital data , particularly beneficial in electrically
noisy environments and for transmission over long distance.
For medical tests:
the patient is isolated from data acquisition system and from any other high voltage
source.
Optional Single mode transmitter and receiver allows 30dB optical budget for longer range.
Isolates delicate
test equipment from computer-generated noise and spikes: noises from computer
does not return into your system.
Eliminates the formation
of "ground loops" (when two instruments are connected to separate power
lines or have a difference between their ground voltage potentials).
Total protection of
signal processor's input stage from lightnings, High Voltage spikes etc.
Replaces bulky multi-wire
cables with compact fiber optic cable - especially important when rewiring existing
ducts

Ordering
Information
The AFL-160 may be ordered with Single-Mode or Multi-Mode receivers and transmitters.
SIngle mode transmitters work in a different wavelength than Multi-mode transmitters and they cannot be combined!
Each side needs a seperate power supply or battery. All units , on the same side, which share the same common ground, may use the same power supply
A stabilized
power supply may supply power for up to 5 (optionally
10) receivers or transmitters (with 16 I/O lines each) |
EXAMPLE:
TRANSMITTER
/ RECEIVER PAIR:
AFL-160
- TT - REL - MM - R
Where:
TT = TTL Input voltage range(0-5V).
REL = Relay Outputs(standard). TT = TTL outputs.
MM= Multi-Mode Transceivers. SM
= Single Mode Transceivers
R
= Range in meter
