The ADAM-4017 is a 16-bit, 8-channel analog input terminal that offers programmable input ranges on all channels. This module is an extremely cost-effective solution for industrial measurement and monitoring applications. Its opto-isolated inputs provide 3000 VDC isolation between the analog input and the module, protecting the module and peripherals from damage caused by high input line voltages. ADAM-4017 provides signal conditioning, A/D conversion, and RS-485 digital communication functions. The module protects your devices from ground loops and voltage spikes through opto-isolation of A/D input and transformer based isolation up to 3000 VDC. The ADAM-4017 uses a 16-bit microprocessor-controlled sigma-delta A/D converter to convert sensor voltage or current into digital data. The digital data is then converted into physical units. When prompted by the host computer, the module sends the data to the host via a standard RS-485 interface.
