Advantech’s RS-485 I/O Modules, ADAM-4000 series, are the perfect choice for establishing a cost-effective remote I/O system. Customers can benefit from ADAM-4000 modules through its simple wiring using only two wires to communicate with their controller or other RS-485 devices. ADAM-4000 modules use the EIA RS-485 communication protocol; the industry's most widely used bi-directional, balanced transmission line suitable for industrial environments.
The ADAM-4000/ 4100 series featuring rugged industrial-grade cases are specially designed for reliable operation in harsh environments. Built-in microprocessors independently provide intelligent signal conditioning, analog I/O, digital I/O, data display, and RS-485 communication through Modbus RTU protocols.

FAQ: How to Select the Right Remote I/O for Your Industrial Applications?
The article will take you through step-by-step beginning with an analysis of the advantages of Remote I/O, its physical interfaces, protocols, and I/O functions to choose the right Remote I/O that suits your industrial needs.
Analog input modules provide various sources of input, such as thermocouple, RTD, thermistor or general analog signals. These modules use EIA RS-485 communication protocol – the widely used bi-directional, balanced transmission line standard in the industry. ADAM-4000 supports Modbus / RTU protocol as a remote data transmission mechanism as well.
Advantech offers versatile I/O devices from sensor modules, add-on DAQ cards or portable modules to remote I/O and wireless I/O devices and software tools, which not only satisfy data acquisition, measurement, control, and communication needs but also allows cloud integration for wider area data management systems.
