Communication input isolator, inputs digital communication signals, outputs after isolation and transmission, and simultaneously provides power supply to instruments. This product requires independent power supply, with three-port isolation of input, output and power.

Note:Three-port isolation of input, output and power. 24V DC independent power supply; input side connects to RS-485 digital signals; output side outputs RS-485, RS-232 or RS-422 digital signals according to model selection; can provide power distribution to field instruments (0/5V/6V/8V/9V/12V DC, set by DIP switch). Transmission rate ≤56kbps, transmission delay ≤5μs. Module indicators: green power indicator, communication status indicator, red fault signal. All terminals are hot-swappable. Specific terminal numbers are subject to the silkscreen on the side of the module.

Ordering information:

  • The output communication protocol and power distribution voltage requirements must be specified when ordering.
  • Original factory example: RS485 input, RS485 output, adjustable power distribution voltage, model SC3091.
