Advantech ADAM-4068 8-Channel Relay Module

The Advantech ADAM-4068-C is an eight-channel relay output module designed for remote I/O expansion in industrial automation, providing eight independent relay outputs that can be controlled from a central Modbus-enabled host. It uses a Modbus RTU over RS-485 serial interface and is intended for use with Advantech's ADAM remote I/O ecosystem, enabling scalable, modular expansion of digital output points. Each channel acts as a relay output, and the unit stores its configuration data in EEPROM to help ensure reliable startup and consistent operation after power cycles. The ADAM-4068-C is part of the ADAM-4000 family of I/O modules, a common choice for automation and building-management applications that require remote switching of loads such as motors, valves, or indicators. Designed for easy integration with PLCs, SCADA, and PC-based control software that communicate via Modbus on RS-485.
