RS-485 I/O Modules: ADAM-4000/4100

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.

RS-485 Serial I/O: ADAM-4000/4100 Series

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.
