ExpertDAQ Digital Input module 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 EX9051D-M has 16 isolated channels with a high input impedance. The Digital Input RS485 module has a special input, allowing high input voltages for Digital Level 1. The Digital Input RS485 module has a LED-display for each channel and was developed for use in a wide temperature range.
