EL817(S)(TA)-G Typical application Circuitry

EL817(S)(TA)-G

Optocouplers, sometimes referred to as optical isolators, like the EL817(S)(TA)-G, are components made to use light to carry electrical signals between two separated circuits. It is made up of a phototransistor and an infrared LED that enable signal communication and electrical isolation. This device is widely used in applications requiring electrical isolation to protect sensitive electronics from voltage spikes, eliminate ground loops, or for safety reasons.

Application Scenarios

EL817(S)(TA)-G is suitable for a wide range of applications, including but not limited to, signal isolation in communication systems, interfacing microcontrollers with high-voltage circuits, power supply regulation, and in digital logic circuits where electrical isolation is necessary. A specific application could be in a microcontroller-based system for controlling an AC load via a relay.

Parameter Features

The EL817(S)(TA)-G features high electrical isolation (typically several thousand volts), a Current Transfer Ratio (CTR) that indicates the efficiency of the optical coupling, and compatibility with a wide range of input and output voltage levels.Its excellent reliability and low power consumption are designed in.

Circuit Connection Example: Microcontroller-Based AC Load Control via Relay

In a microcontroller-based system for controlling an AC load, EL817(S)(TA)-G can be used to isolate control signals from the microcontroller to the relay driving the AC load.

- Microcontroller to LED Connection: Connect the anode of the internal LED to a digital output pin of the microcontroller through a current-limiting resistor, and connect the cathode to the ground of the microcontroller circuit. This setup allows the microcontroller to control the LED, which in turn controls the phototransistor.

- Phototransistor to Relay Coil Connection: Connect the collector of the phototransistor to one end of the relay coil, and the other end of the coil to the positive supply voltage. The phototransistor's emitter is linked to the power side circuit's ground. The phototransistor conducts based on the LED's light, energizing the relay coil and switching the relay.

- Current-Limiting Resistor: To prevent damage to the LED and limit the current flowing through it to safe levels, connect a resistor in series with it.

- Flyback Diode: Place a diode across the relay coil in reverse bias to protect the circuit from voltage spikes generated when the relay coil is de-energized.

- AC Load Connection: Connect the AC load to one of the relay's switch contacts, and connect the other contact to the AC supply line.Relays govern how the AC load is connected to the supply by acting as switches.

When designing circuits with EL817(S)(TA)-G, it's essential to consider the current and voltage requirements of the LED and phototransistor to ensure they operate within their specified limits. The forward voltage and current of the LED, as well as the output voltage of the microcontroller, should be used to calculate the value of the current-limiting resistor. Additionally, the isolation voltage rating of the optocoupler must exceed the maximum voltage that might appear across the isolation barrier to ensure safety and reliability. Proper PCB layout practices should be followed to maintain the integrity of the electrical isolation and minimize noise coupling.
