Introduction

The ioThinx 4530 Series is a versatile Linux-based controller with support for I/O and serial expansion modules. Equipped with a Cortex-A7 dual-core CPU, 2 GB of memory, and 3-in-1 serial interfaces, the ioThinx 4530 Series offers robust performance. These controllers can support up to 64 units with the dedicated 45MR Series modules, including digital and analog I/O, relay, and temperature modules. In addition, the ioThinx 4530 Series supports up to five 45ML Series serial modules.

Moxa Industrial Linux 3 (MIL3)

The ioThinx 4530 Series runs on Moxa Industrial Linux 3 (MIL3), an industrial-grade Linux distribution based on Debian. Developed and maintained by Moxa, MIL3 is specifically designed to meet the security, reliability, and long-term support requirements of industrial automation systems.

Key Features

Small Footprint With High-density I/O Points

A single ioThinx 4530 Series controller fully equipped with expansion modules can support up to 1,024 digital I/O points while maintaining a remarkably small footprint, measuring less than 10 cm (3.9 in) wide and 6.1 cm (2.4 in) tall. The 45MR Series modules come in even smaller at 1.8 cm (0.7 in) width. This compact design allows for installation in limited spaces, enhancing the simplicity and maintainability of your control cabinet.

Flexible Modular Design to Expand I/O and Serial Interfaces

Featuring a flexible modular design for expanding I/O and serial interfaces, the ioThinx 4530 Series enables users to effortlessly modify the combination of expansion modules to suit various application scenarios. This modular capability helps developers seamlessly migrate programs from one project to another.

Easy Tool-free Installation and Removal

The ioThinx 4500 Series has a unique mechanical design that reduces the amount of time required for installation and removal. Screwdrivers and other tools are not required for any part of the hardware installation, including mounting the device on a DIN-rail, as well as connecting the wiring for both communication and I/O signal acquisition. Furthermore, no tools are required to remove the ioThinx from a DIN-rail. Removing all of the modules from a DIN-rail is also easy using the latch and release tab.
