1, Product Introduction:

The structure of the photorelay: In the case of the ORIENT OR-440AS, the input side of the photorelay is equipped with an infrared led, and the output side is equipped with a photodiode array (hereinafter referred to as "PVG") and MOSFETs. Figure 1 shows an example of the internal structure of the 2.54SOP4 package, which is one of the photorelay unfolded packages. The LED on the input side and the PVG on the output side are placed face to face and are insulated with resin.

Figure 1. 

 

The working principle of the photoelectric relay OR-440A. The photorelay works by applying a current to the LED on the input side. The PVG on the output side then receives the infrared light from the LED, generating the electromotive force. This electromotive force drives the connected MOSFET gate, which opens the MOSFET.

The contact structure of optical relay form A is contact type, and the output side opens when a certain amount of current is applied to the input side. This contact type is also called normally open type. Denoted as 1a, denotes the 1-pole a contact relay and the 2-pole a contact relay, denoted as 2a. On the other hand, when a certain amount of current is applied to the input side, the output side of the form B contact type remains closed, and when the input current is below a certain level, the output side turns on. This type of contact is also known as normally closed contact. Denotes 1 pole b contact relay, denoted 1b; 2-pole b contact relay, marked 2b. The photorelay A uses an enhanced MOSFETs and the photoelectric relay B uses a depletion MOSFETs.

2,The application

1). The ORIENT Photorelay function is used in the circuit to monitor the charging voltage of the battery unit. The relay is expected to produce many contacts, and photoelectric relays are highly recommended because they do not have such a concept as contact life (long life). Advantages: Small size, long life, high withstand voltage.

2). The ORIENT Photorelay is used as a switch for the light and sound output of camera sets. Advantages No noise, long life, small size

3). ORIENT Photorelay is used to monitor insulation deterioration of battery cells. If the insulation in the unit deteriorates, when the relay is switched on, the ground fault current passes through and the sensor detects the current. The high load voltage type Photorelay is the ideal high voltage battery.
