Photoelectric isolation RS485 typical circuit diagram

First, RS485 bus introduction The RS485 bus is a common serial bus standard that uses balanced transmit and differential receive, and therefore has the ability to reject common-mode interference. The RS485 bus is one of the most widely used buses when some communication distances are required fr

NE555BU406 Nd Yag Rod Nd Yag Rod is a purple laser crystal, which are widely used for laser cutting, medical instrument @1064nm. It is suitable for a variety of laser working modes (continuous, Pulse, q-switch, mode locking, frequency doubling, etc.), widely used in industry, m

Damping resistor

Damping resistors are named for their role in the circuit. In order to prevent the loop from oscillating, some circuits use series or parallel resistors in the line to consume some of the energy that can cause oscillation. This resistor is called a damping resistor. First, the damping resistance
