MOXA NA-4020 INTRODUCTION
The ioLogik 4000 Series is suitable for remote monitoring and alarm systems, such as those used for water treatment systems, water supply systems, wastewater treatment systems, and power monitoring systems. These kinds of applications need more I/O points and a variety of I/O types, including temperature sensors, gas detectors, and water quality detectors, all of which can benefit from the versatile mixture of I/O features supported by the ioLogik 4000 Series.
Slice Form Factor and Flexible I/O Variety
The unique modular construction of the ioLogik 4000 Series allows for the mixing and matching of modules to achieve the best combination of I/O modules to meet the needs of a wide range of remote automation applications. An industrial modular housing enables I/O modules to be added to the base unit without a backplane. The ioLogik 4000 Series is perfect for space-limited applications, and high-density I/O points are provided for greater flexibility and expandability. Modules can connect to virtually any type of sensor, including but not limited to those for temperature, pressure, flow, voltage, current, and contact closure.
Easy Maintenance
The ioLogik 4000 Series comes with removable spring-type terminal blocks (RTBs) that allow you to conserve field wiring for future use.
