ISA Serial Boards CI-132 Series Moxa vietnam

Features and Benefits 

  • Economical RS-422/485 ISA boards with two DB9 male connectors on the board for easy wiring
  • RS-485 data direction control with ADDC® or by RTS
  • 921.6 kbps maximum baudrate for super fast data transmission
  • 16-byte FIFO and on-chip hardware flow control
  • Surge protection and electrical isolation available
  • Built-in termination resistors



The CI-132 series ISA boards come with 2 independent RS-422/485 serial ports for connecting data acquisition equipment and other serial devices to a PC. Connect your devices over longer distances—up to 1.2 km (4000 ft)—and ensure greater reliability in industrial environments with on-board surge protection and electrical isolation (available with some models). Enjoy greater versatility by using point-to-point full duplex connections, or set up a half duplex RS-485 multi-drop network.
