MOXA NA-4020 / NA-4021
Product is End of Life : 2022-01-01
RS-232/485 (Modbus/RTU) network adapters
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 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. The ioLogik 4000 series features an industrial modular housing that allows I/O modules to be added to the base unit without a backplane. The width of each module is only 12 mm, perfect for space-limited applications. The ioLogik 4000 series provides high density I/O points for greater flexibility and expandability. The modules can connect to virtually any type of sensor, including but not limited to those for temperature, pressure, flow, voltage, current, and contact closure.
The NA-4020/4021 series network adapter can be expanded by adding up to 32 I/O modules. It can provide spring type, removable terminal blocks (RTBs) that allow you to preserve field wiring before replacing an I/O expansion module. Each I/O expansion module can be replaced quickly and easily.
