4 line BdC 20 mA (With galvanic isolation and line protection)

Features:

• Asynchronous communication board 4/8 high flow ports, up to 3,75 Mbps (1)
• FIFO of 128 octets on each way for emission or for reception
• Mode RS232, RS422, RS485, Power (current) loop 20 mA, TTL
• Interface in external metallic connection case
• Extra protection against lightning ESD (of more than 22 kV)
• Automatic reversal of line under RS485
• Driven like standard COM ports

Note 1 : tandard maximum speed is 1.8 Mbps (29.4912 Mhz oscillator) and can go up to 3.75 Mbps (optional 60 Mhz oscillator). Other oscillators can be mounted on the board to satisfy communication speed specific requirements.

Connections:

• Link between board and case by reinforced round cable and a vibration resistant link
• Case RS232 : 4 or 8 SUB D25.
• Case RS422 without insulation: 4 or 8 SUB D25.
• Case RS422/ RS485 isolated 3 KVeff: SUB D9 for each channel.
• current loop case 20 mA isolated: SUB D9 for each channel.
• Mode TTL without case: connector MDR 100 points.
• Modular case with mixed interface (RS232, RS422, RS485, fiber optic cable).

Signals:

• Under RS232: TxD, RxD, RTS, CTS, DSR, DCD, DTR, RI.
• Under RS422: TxDa, TxDb, RxDa, RxDb.
• Under RS485: +Tx/Rx, -Tx/Rx.
• Under current loop 20 mA: +TxD, +RxD, -TxD, -RxD.

Adressing:
