ASCII/Modbus RTU 8 × Universal Analog Input Module

ADAM-4019+ is an 8-channel Universal Analog Input Module. The new module improves over its predecessor ADAM-4019 with a 4~20 mA input range, and a burnout detection function. Its mixed input range design supports individual configuration for each channel to save costs and space in applications. The other frequently used input ranges include +/-10V, mV, and thermocouple, which are all well-integrated in this model. It also supports burnout detection so that any sensor failures can be detected in advance. For easier control, ADAM-4019+ provides not only ADAM ASCII commands, but also the Modbus/RTU protocol for satisfying different application demands.


  • Supports 4 to 20 mA
  • Software configurable for mV, V, mA or Thermocouple inputs
  • 16-bit resolution
  • Isolation voltage 3000 VDC
  • Supports Modbus/RTU Protocol
  • Burn-out detection function

Like most of the ADAM-4000 series IO modules, this unit can configured (with the utility linked below) to respond to either Advantech's ASCII serial protocol or Modbus RTU.

Configuration of the unit is performed with the ADAM.NET utility for Windows. Running the utility requires the .NET framework version 1.1 or later.

The ADAM series all come with a DIN-rail and panel mount adapter. Multiple units can be stacked on top each other for high density installation.
