ExpertDAQ Digital IO modules communicate via RS485 and are available with Modbus RTU. Within one RS485-network up to 256 modules may be controlled. Without a RS485 Repeater the maximum cable length is 1200m. The RS485 Digital IO module are sturdy, power saving and easy to use.

The EX9050HD-M has 8 digital Input (source) and 8 digital open-collector Output (NPN). The Digital IO RS485 module can emit currents of 30mA at 3,5 to 30V and has a LED-display for each channel. The Digital IO RS485 module was developed for use in a wide temperature range.
