APCI-7420-3Two-port PCI serial board with galvanic isolation
- Manufacturer
Each port takes the operating mode of the MX module fitted: RS232, RS422, RS485 or 20 mA current loop, with the galvanic separation carried by the module itself.
Transmission speed is programmable up to 115.2 kBaud and the crystal option reaches 1 MBaud; the 128-byte FIFO buffer per direction limits interrupts towards the CPU. Declared isolation is 1000 V.
At a glance
- Memory: Buffer FIFO 128 byte per porta (TX/RX)
- Serial interfaces: 2× RS-232/422/485/20 mA CL (configurabili via moduli MX, fino a 115,2 kBaud; 1 MBaud con opzione Quarz)
- Channels: 2
- Isolation voltage: 1000 V (MX-Module)
- Board function: Serial
