.Optoisolators - Transistor, Photovoltaic Output are used in a variety of applications. This article examines the application field and working principle of FODM452R1.
FODM452R1 is a two-channel DC-isolated transistor output optocoupler. It is suitable for galvanically isolating an input signal from output circuitry when the output load includes a transformer. It features high levels of electrical isolation between the input and output, and provides optical-to-electrical coupling for passing digital or analog signals between adjacent circuits or devices. It is designed to meet various UL, CSA, IEC, and VDE approvals.
FODM452R1 features both photovoltaic and relay mode outputs with two signal isolated channels. Photovoltaic mode works by illuminating a light emitting diode (LED), which generates a small current for operating a photodiode in a feedback loop. The photodiode rectifies the light to generate a voltage and this in turn, energizes and switches on the output terminal.
In relay mode, FODM452R1 operates at a higher input current than photovoltaic mode. It is driven by a current modulated LED, which operates at a nominal input current of 40mA. The light emitted by the LED is detected by a Remote Emission Photovoltaic (REV) photodiode. When the photodiode senses a light signal, a voltage is generated that switches on and drives the output terminal.
The use of FODM452R1 in applications ranging from telecommunications systems to industrial automation control systems allows multiple circuits or devices to be isolated electrically, while the data signals or analog values remain intact. This optocoupler requires very low input current, making it an ideal choice for applications where power consumption must be minimized.
FODM452R1 also features an isolation rating of 3750VDC, which ensures that the input circuitry is fully isolated from the output circuitry. It is also RoHS compliant and can handle peak power surges of up to 150V, making it suitable for use in most environments.
In summary, FODM452R1 is a versatile two-channel DC-isolated transistor output optocoupler that can be used for a variety of applications and is suitable for galvanically isolating an input signal from output circuitry. It features both photovoltaic and relay mode outputs with two signal isolated channels, and offers high levels of electrical isolation and very low power consumption. Its 3750VDC isolation rating ensures maximum protection from electrical interference and ensures the signal remains intact.
