The PSM-ME-RS232/RS485-P bi-directionally converts RS-232 interface signals to the RS-485 2/4-wire and RS-422 standard.

With support for 4-wire balanced full duplex communication, or 2-wire half-duplex, the PSM-ME-RS232/RS485-P is suitable for most applications, including industrial, commercial and any general office computer device. Transmission speeds of 1.2 kbps up to 115.2 kbps can be applied to point-to-point and point-to-multipoint networks.

Use the PSM-ME-RS232/RS485-P in all common bus systems with UART/NRZ data format and character length of 10/11 bits. This is the best “plug and play” solution for converting RS-232 (V.24) to RS-422 (V.11) and RS-485, with electrical isolation.

RS232 to RS485 Converter Features

  • RS-422 4-wire for point-to-point operation
  • RS-485 2-wire operation, half duplex
  • RS-485 4-wire operation, full duplex
  • Automatic transmit/receive changeover
  • Transmission speed from 1.2 kbps up to 115.2 kbps
  • Integrated data indicator for dynamic indication of transmit and receive data
  • High-quality 3-way isolation between power supply, V.24 (RS-232), and RS-422/485 for reliable decoupling of the potentials with 1.5 kV
  • Integrated surge protection with transient discharge to the DIN rail
  • Shipbuilding approval per DNV
