Our wireless serial I/O interfaces provide an easy way to connect sensors, transducers and switches into a wireless communication system. Operating in point to point exception reporting or MODBUS RTU modes, this range of products is suitable for projects that require 0-20mA, 4-20mA, 0-10V, digital and pulsed I/O. Devices can convert between mA and voltage to interface many different sensor types into a single network. When deployed with the WLN-2000, a complete MODBUS solution for I/O with third party devices is realized to reliably and securely transport data over a distance to a control room from several remote site locations. In a simpler form, digital and analogue data can be communicated over a distance of several miles / kilometers available as user-defined outputs. Combinations available include:

  • SIO-110DX - MODBUS Serial I/O, 16 digital channels with RS232/485 interface.
  • SIO-120AI - MODBUS Serial I/O, 8 digital I/O with upto 8 AI and RS232/485 interface
  • SIO-130AO - MODBUS Serial I/O, 8 digital I/O with upto 8AO and RS232/485 interface
