Advantech ADAM-4019+| 8-Channel Universal Analog Input

The ADAM-4019+ is built for applications where multiple analog signal types must be captured at a remote location and delivered back to a PLC or SCADA system over RS 485. With 8 differential inputs and channel independent configuration, the module supports flexible signal assignments across channels, allowing one device to consolidate voltage and current loop measurements in a single compact node. Its support for both Modbus RTU and ASCII commands makes it compatible with common industrial controllers and serial gateways.

Designed for industrial stability and protection, the ADAM-4019+ provides 16 bit resolution and a total sampling rate of 10 samples per second across all channels. It features 3,000 VDC isolation, built in TVS and ESD protection, and a watchdog timer system rated at 1.6 seconds for system and communication monitoring. With multiple input ranges spanning low level millivolt signals through standard voltage and current loop ranges including 4 to 20 mA, the ADAM-4019+ is a practical universal analog input choice for process monitoring, equipment diagnostics, and distributed instrumentation.
