ADAM-4000 – RS-485 I/O Modules with Modbus by Advantech

The Advantech ADAM-4000 series represents a comprehensive family of RS-485 I/O modules engineered for robust industrial data acquisition and control applications. This versatile product line includes three specialized modules: the ADAM-4118 offering 8 differential thermocouple input channels supporting J, K, T, E, R, S, B, and N type thermocouples along with voltage and current measurement modes; the ADAM-4150 providing 15 channels of digital I/O with 7 digital inputs and 8 open collector outputs supporting counter, frequency, and pulse output functions; and the ADAM-4168 featuring 8 Form A relay outputs rated for both AC and DC loads. All modules in the ADAM-4000 family share common industrial-grade specifications including 3000 VDC isolation voltage, extended operating temperature from -40 to 85°C, and wide power input acceptance from 10 to 48 VDC unregulated. The modules communicate via RS-485 interface and support both ASCII Command and Modbus/RTU protocols for seamless integration into existing SCADA and automation systems. Built-in watchdog timers ensure system reliability, while plug-in terminal block connectors simplify field wiring. The ADAM-4118 thermocouple module features 16-bit resolution, burnout detection, and built-in TVS/ESD protection for signal integrity. The ADAM-4150 digital I/O module supports 3 kHz counter input and 1 kHz pulse output capabilities, while the ADAM-4168 relay module delivers 100 Hz pulse output with 10ms typical total switching time. These modules are ideal for factory automation, process control, building management, energy monitoring, and environmental monitoring applications. FCC and CE certified with RoHS compliance, the ADAM-4000 series provides reliable remote I/O connectivity for industrial networks.
