The ioLogik R1200 Series RS-485 serial remote I/O devices are perfect for establishing a cost-effective, dependable, and easy-to-maintain remote process control I/O system. Remote serial I/O products offer process engineers the benefit of simple wiring, as they only require two wires to communicate with the controller and other RS-485 devices while adopting the EIA/TIA RS-485 communication protocol to transmit and receive data at high speed over long distances. In addition to communication configuration by software or USB and dual RS-485 port design, Moxa’s remote I/O devices eliminate the nightmare of extensive labor associated with the setup and maintenance of data acquisition and automation systems. Moxa also offers different I/O combinations, which provide greater flexibility and are compatible with many different applications.

Easy-to-Use Software Interface for Easy Maintenance

With Moxa’s easy-to-use ioSearch software, you can quickly access all of an ioLogik R1200 device’s status information and settings with a user-friendly graphical user interface. Furthermore, ioSearch also provides an easy method for updating firmware for all ioLogik R1200 devices over an RS-485 network, so you can even update your firmware remotely. The free and easy-to-use ioSearch software reduces the maintenance time and labor required to set up your communication interface. When more than one ioLogik R1200 are on the same RS-485 network, you no longer need to turn hundreds of dials during setup. Instead, simply configure and duplicate each ioLogik R1200’s baudrate and mode through the graphical user interface. This convenient software feature reduces maintenance engineers’ effort, and greatly simplifies upgrading your device’s configuration compared with more traditional methods.

Innovative Hardware Design Reduces Deployment Effort and Enhances Maintenance Efficiency

With the industry’s first RS-485 serial remote I/O with USB design, Moxa provides an innovative solution for upgrading and configuring RS-485 remote I/O communication devices and firmware. All you need to do is upload the configurations to a USB drive, plug it into the field device, and all the configurations and firmware updates will upload to the field device automatically.

Cost-Saving Hardware Design for Backup and Redundancy

Moxa’s ioLogik R1200 Series provides dual RS-485 ports so that when one of your RS-485 ports is damaged, you can quickly switch to the other RS-485 port for quick testing or repair. RS-485 remote I/O devices are already considered a low-cost technology, but with dual RS-485 ports, Moxa helps you save a little bit more. With the ioLogik R1200, you can take advantage of our dual RS-485 ports to set up wiring, provide computer redundancy, or back up your network using two computer topologies. For wiring redundancy, when your computer detects that one of the RS-485 connections is not responding, it can quickly switch over to the other RS-485 line to guarantee continuous communication between field sensors and the central computer. Furthermore, users have the freedom to define the settings. For computer redundancy, the ioLogik R1200 provides system operators with a secure backup when one system goes down.
