Using the original SP3232, SP3485, stable performance, up to industrial-grade design standards, the realization of the 232 signal and RS485/RS422 signal conversion, automatic transceiver conversion, no need to “receive - send” control, so that the two ends of the interface communication more quickly and stably
Standard DB9 and 5.08mm plug-in terminals, the circuit adopts 5V power supply, need to access the power supply voltage at the 485/422 end.
Multiple isolation devices + circuit protection
1. On-board digital isolator with excellent performance characteristics and reliability, signal isolation, so that the transmission of the signal more stable
2. On-board DC/DC power isolation, can provide stable isolation voltage and output short circuit protection, isolation end without additional power supply
3. RS232 terminal with overcurrent protection, surge protection. It can ensure stable output of current and voltage, and strong shock resistance.
4.RS485/422 terminal with overcurrent protection, surge protection, lightning gas discharge protection circuitry
5. On-board TVS (transient voltage suppression tube), can effectively reduce the surge voltage and transient spike voltage in the circuit
6. On-board self-recovery fuses to ensure stable current and voltage output, reduce over-current and over-voltage as well as the impact of electrostatic discharge.
7. On-board GDT gas discharge tube, you can use the discharge tube to drain the powerful lightning current into the ground.
120R termination resistor pad is reserved on the board, which can increase the stability of signal transmission and reduce interference.
Baud rate support range:
RS422: ≤ 2M bps (since the transceiver test, the actual use of the equipment need to refer to both ends of the baud rate range)
RS485: ≤2M bps (non-standard value, actual use should refer to the baud rate range of the equipment at both ends)
Onboard two LED indicators, used to indicate the circuit signal status
232-end indicator: 232-end received signal indicator, that is, the signal flow for the 232 -> 485/422, the LED blinking
422/485 end indicator: 422/485 end receive signal indicator, that is, when the signal flow direction is 485/422 -> 232, the LED blinks.
