XIO Module
Input / Output Controller for Plant Automation and Control
XIO industrial modules are designed and manufactured by MINDS to handle all digital and analog inputs and outputs for complete control of your asphalt/hotmix, emulsion, or modified bitumen plant. Build to last: deployed at hundreds of plants all over the world.

XIO - Multiple Inputs/Outputs Controller
XAF - Analog/pulse Interface
XEL - Logic Input Interface
" The quality and stability of the mix produced is incredible. I even had samples tested independently as it was almost unbelievable. All plant equipment is controlled on screen eliminating consoles, button and the likes. This allows for easier maintenance and operator training. The interface is user friendly and my operators had no difficulty at all getting used to it. MINDS accompanied us all the way giving us useful and pertinent insight into the control part of the design, saving a lot of time and errors. We bought another plant in 2010 and we stripped the old control system out without hesitation. "

XIO Module Highlights
Unique architecture
The XIO module is a multiple input/output controller used in our automation and control systems. This module is characterized by its unique architecture, compactness and robustness and uses a TCP/IP communication protocol over an Ethernet link. The XIO module is equipped with logic input and outputs, analog and frequency input-outputs, each type in a calculated proportion that just one type of module is needed to control an asphalt plant. Thus, a small application requires one or two XIOs. To increase capacity additional XIOs, all identical to the first one, can be added to increase the number of input-outputs. A very large plant with comprehensive automation can require six XIOs or more.
The advantages of this architecture are numerous:
- Only one module is needed as a spare part
- Guaranteed flexibility and extensibility
- Simplified systematic wiring
- Support and maintenance facilitated
- Inherent generation of spare inputs and outputs
Comparison with traditional architecture
In a traditional installation using a field network, electronic modules ensuring the input-outputs are specialized according to the type of signals: logic inputs, logic outputs, analog inputs, analog outputs, etc., this architecture multiplies the number and types of electronic modules (refer to Classical Architecture). With the XIO, only one standard device is necessary, having all the types of input-outputs onboard (refer to XIO Architecture). When the number of input-outputs is very important, the cost of the two solutions is similar, but on small and average installations, in an example of road construction plants, the architecture of XIO reduces costs and becomes more profitable. In all cases spare parts management is much easier with the XIO architecture.
