Interface converter - PSM-ME-RS232/RS485-P

Interface converter, for converting RS-232 (V.24) to RS-422 (V.11) and RS-485, with electrical isolation, 2 channels, rail-mountable

  • RS-422 4-wire point-to-point operation
  • Mounting on standard EN DIN rails
  • Transmission speed of 4.8 Kbps ... 115.2 Kbps
  • High-quality 3-way isolation between power supply, RS-232, and RS-422/RS-485 for safe decoupling of potentials with 2 kV
  • RS-485 2-wire operation, half duplex
  • RS-485 4-wire operation, full duplex
  • Automatic RS-485 transmit/receive changeover
  • Integrated data indicator for dynamic indication of transmit and receive data
  • Integrated surge protection with transient discharge to the DIN rail
  • Shipbuilding approval in accordance with DNV GL and ABS
