DDAM-8520 is a industrial-grade Serial converter with bidirectional conversion between RS-232 to RS-485/422 and also a RS-485/422 repeater. Thus this device can be used for bidirectional data conversion between serial signals like RS-232 to RS-485/422. It can also be used as a repeater for RS-485 and RS-422 transmission. It provides 1 RS-232 serial port and 2 RS-485/422 serial ports. The Serial port has a 1500W surge protection, 15kV electrostatic protection and 3kV photoelectric isolation protection, thus it effectively prevents device from being damaged due to surge or high voltages in noisy enviorenmets.
