Optoisolators - Triac, SCR OutputOptoisolators are devices that use optical coupling to separate electrical circuits, often from one another, while providing electrical insulation between circuits. EL3010S1(TB)-V optoisolators are a type of Triac and SCR Output optoisolator, and are used in various applications to provide isolation and other benefits.The EL3010S1(TB)-V optoisolator includes a 6144–55 LED coupled to a MCR100. The LED has a forward current of 20mA which is split between the two opposing terminal contacts called the Anode and Cathode.  The LED also has a nominal peak forward voltage at 1.48V. The integrated MCR100 has two SCRs connected in an inverse series configuration along with a diode to provide the extension of the Anode and Cathode signals.The two SCRs are designed for direct AC/DC or DC/AC conversion. This means that the current will only flow through the EL3010S1(TB)-V optoisolator when it is triggered. This trigger is provided by the LED which emits a light when a current is applied to the Anode and Cathode. The light emitted is detected by the MCR100 and generates a signal at the output that switches as the input current is applied or removed.The EL3010S1(TB)-V optoisolator is ideal for applications such as interfacing a low voltage DC control drive to a 240V AC mains line in order to switch mains-powered devices on/off remotely. The optoisolator allows for electrical isolation between the mains and low voltage circuits, providing protection for the control circuit and increased safety for users of the system.The EL3010S1(TB)-V optoisolator can also be used as part of an AC power control system. In this application the optoisolator would be connected to an AC mains line (say a residential supply) as an interface in the circuit. The optoisolator isolates the AC signal to provide protection for the device controlling the AC circuit. So when a low voltage signal from the control device is passed through the optoisolator it triggers the MCR100 to activate the SCRs, so providing the switching control to the AC circuit.This type of optoisolator can also be used in the control of motors and other AC powered devices. This is due to the EL3010S1(TB)-V optoisolator having a zero voltage triggering capability. This means that, when the Anode and Cathode are connected to an AC source, the latching circuitry of the SCRs will trigger both simultaneously allowing the circuit to control the AC power device.In summary, EL3010S1(TB)-V optoisolators are a type of Triac and SCR Output optoisolator designed for the effective electrical isolation of circuits. The optoisolator provides a cost-effective solution to controlling AC and DC powered devices and offers enhanced safety for users. These optoisolators can be used in various applications to provide isolation and control of the current flowing through the circuit.
