USC-W232D is an industrial grade galvanic isolated RS232 to RS485 converter which can convert RS232 signals to balanced differential RS485 signals in both directions.
Built-in power isolation makes sure the supply voltage is properly isolated from the signal voltage. The supply voltage is completely isolated from the isolated terminals. This RS232 to RS485 converter also
has built-in isolation for the signal lines providing error-free and clean data communication while avoiding electrical interference, surges and voltages spikes damaging the data signal and connected equipment. Onboard TVS (Transient Voltage Suppressor) and ESD protection, effectively protects against surge voltages and transient peak voltages in the circuitry and provides
protection against static electricity. An onboard self-recovery fuse and protection diodes, ensures a stable voltage output, and protects against
over-current and over-voltages.
If you have a long communications distance, a terminal resistor can be an advantage. A 120 ohm terminal resistor can be enabled by a jumper located under one of the screw terminals.
LED indication lights for Power and the TX / RX signals indicates when data is transmitted or received, which is a great help when troubleshooting a setup.
As a true industrial grade converter, this RS232 to RS485 converter has a wide input voltage range of 5V - 36V DC.
