This product requires independent power supply, with three-port isolation of input, output and power.<\/p>\n<p><strong>Note:<\/strong>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 \u226456kbps, transmission delay \u22645\u03bcs. Module indicators: green power indicator, communication status indicator, red fault signal. All terminals are hot-swappable.
