ADAM-4117 – 8-ch Analog Input Module with Modbus by Advantech

The ADAM-4117 from Advantech is a robust 8-channel analog input module designed for industrial data acquisition and remote monitoring applications requiring reliable signal measurement in harsh environments. This versatile module supports both Modbus RTU and ASCII command protocols, enabling seamless integration with a wide range of SCADA systems, PLCs, and industrial controllers via RS-485 communication interface. The ADAM-4117 features eight differential analog input channels with independent configuration capability, allowing simultaneous monitoring of different signal types including millivolt, voltage, and current inputs. Each channel delivers 16-bit resolution with exceptional accuracy of ±0.1% for voltage mode and ±0.2% for current mode measurements. The module supports extensive input ranges from 0-150mV to ±15V for voltage signals and 0-20mA or 4-20mA for current measurements, providing flexibility for diverse sensor and transmitter applications. Built for industrial reliability, the ADAM-4117 operates across a wide temperature range from -40 to 85°C and accepts unregulated power input from 10 to 48 VDC with built-in power reversal protection. The 3000 VDC isolation voltage and 200 VDC high common mode capability ensure safe operation in electrically noisy environments, while built-in TVS and ESD protection safeguard against transient voltage events. Additional features include 92 dB common mode rejection at 50/60 Hz, ±60 VDC over voltage protection, and selectable sampling rates of 10 or 100 samples per second. The compact DIN rail mountable design with plug-in terminal blocks simplifies installation and maintenance. The B version adds micro USB connectivity for convenient configuration. Ideal for factory automation, building management systems, energy monitoring, and process control applications across manufacturing, infrastructure, and industrial sectors.
