Fiber Optic Links

AFL - 220 DIN Rail Fiber Optic Link

AFL - 220 DIN Rail Analog / Contact Closure Fiber Optic Link is an OEM Product designed especially for Industrial Applications. The units may be used for Transferring ±10V Analog Signals or 4 - 20mA Current Loop Signals, together with 2 Contact Closures (or Digital TTL Signals). The User may configure the Analog Input to be -10V to +10V or 4 - 20mA by using a Single Jumper. The Receiver will Output both 4 - 20mA Signal (for Input Range of 0 to +10V or 4 - 20mA, as selected) along with 4 - 20mA Current Loop Signal.

The 2 Digital I/O Lines may be also Configured by the user to 0 to +5V (or +3.3V) Standard TTL signal or to contact closure (i.e. a contact close at the transmitter would cause a contact closure at the receiver). The Receiver Contacts are change-over type so the Operation may be Inverted (Contact Closure at the Input may be configured to Closed or Open Switch at the Receiver).

The AFL - 220 Analog / Contact Closure Fiber Optic Link was designed for System Integrators and Builders, where Low Size, Low Power Consumption and Low Cost are Important. You won't have to keep 3 - 4 different Fiber Optic Links in your toolbox. One Link does it all with few Simple Jumper Configurations.

The Bandwidth of an Analog Input is DC - 5kHz. The Contacts can be switched upto 300 times per second and the TTL Lines can be toggled upto 30,000 times per second. The Distance between 2 Modules may be between 0 to 2 miles with the Standard Multi-mode Interface (30 miles Optional with Single-mode Optical Interface and SM Fiber).

1. Advantages:
2. Low Noise Transfer of Analog or Digital Data, particularly beneficial in Electrically Noisy Environments and for Transmission over Long Distance.
3. For Industrial Applications: DIN Rail Interface, 24V Single Supply.
4. Optional Differential Amplifier Input Stage provides a Differential Input, with Gain of 1 or 10 or 100 (must be configured on time of order), for Direct Connection of any sensor such as: Strain Gage, Piezo, EEG & ECG, Temperature, Humidity, Pressure, etc.
5. Isolates delicate Test Equipment from Computer generated Noise and Spikes: Noises from Computer do not Return into your System.
6. Eliminates the formation of “Ground Loops” (when Two Instruments are connected to Separate Power Lines or have a difference between their Ground Voltage Potentials).
7. Total Protection of Signal Processor's Input Stage from Accidental Sensor Malfunction (e.g. Short to Mains Voltage or a Lightning Shock).
8. Replaces bulky coaxial cables with compact fiber optic cables - especially important when rewiring existing ducts. Interface to existing fibers - Multi-Mode standard, Single Mode optional.
9. Transfers Analog Signals to distances of upto 3km - with 12 bits Accuracy.
