RS232 to RS485 RS422 Serial Converter Industrial Grade Isolated Converter with Overcurrent Surge

About this item

• Feature: 1. SIGNAL CONVERSION: Adopting original SP3232, SP3485, stable performance, up to industrial grade design standard. The module realizes the interconversion of 232 signals and RS485 RS422 signals. On board automatic transceiver conversion circuit, no need for transceiver control, so that the two ends of the interface comm is more rapid and stable. 2. ROBUST AND SMOOTH CONNECTION: The module adopts standard DB9 and 5.08mm pluggable terminal blocks, ensuring smooth insertion and connections. The circuit only uses 5V power supply. When the module works, it needs to access the power supply voltage at the 485 422 terminal. With independent power isolation and signal isolation circuit. 3. ADVANCED SIGNAL ISOLATION: On board digital isolator for signal isolation to make the transmitted signal more stable. On board DC power isolation provides stable isolation voltage as well as output shortcircuit guard, and no additional power supply is required at the isolation end. 4. MULTIPLE GUARD FUNCTION: The 232 terminal is equipped with overcurrent guard and surge guard. RS485 422 terminal is equipped with overcurrent guard, surge guard and gas discharge guard circuit. On board TVS (Transient Voltage Suppressor) can effectively suppress the surge voltage and transient spike voltage in the circuit. On board self recovery fuse ensures stable output of current and voltage, and anti shock. 5. GAS DISCHARGE TUBE AND ANTI INTERFERENCE: On board GDT gas discharge tube can be utilized to drain the powerful thunder current into the earth, so that the subsequent circuits and equipments can avoid being damaged by the surge impact. 120R termination resistor bonding pad is reserved on the board, which can increase the stability of signal transmission and reduce interference. Specification: Item Type: RS232 RS485 RS422 Serial Converter Material: Aluminum Alloy Baud Rate Range: RS422: less than 2M bps (self transmitting test, actual usage needs to refer to the baud rate range of both devices) RS485: less than 2M bps (non standard value, actual usage needs to refer to the baud rate range of both devices) LED indicator: Onboard two LED indicators for circuit signal status 232 End Indicator: Indicator for receiving signal at 232 end, flashes when signal flows from 232 to > 485422 422485 End Indicator: Indicator for receiving signal at 422485 end, flashes when signal flows from 485422 to >232.
