Same as SC3091, input signal is RS232 digital signal, output selectable RS232, RS485 or RS422. Requires independent power supply, three-port isolation between input, output and power supply.
Note:Three-port isolation between input, output and power supply. 24 V DC independent power supply; input side connects to RS232 digital signal; output side outputs RS-485, RS-232 or RS-422 digital signal according to model selection; can provide power supply to field instruments (DIP switch setting). Transmission rate ≤56 kbps, transmission delay ≤5 μs. Module indicators: green power indicator, communication status indicator, red fault signal. All terminals are hot-swappable. Refer to the module side silkscreen for specific terminal numbers.
Ordering information:
- The output communication protocol and power distribution voltage requirements must be specified when ordering.
- Factory example: RS232 input, RS485 output, adjustable power supply voltage, model SC3092-1.
