Advantech ADAM-4018 - "Discontinued" - 8-CHANNEL THERMOCOUPLE INPUT
by Advantech

The ADAM-4017/4018 is a 16-bit,8-channel analog input module that provides 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 V DC of isolation between the analog input and the module, protecting the module and peripherals from damage due to high input voltages. ADAM-4017/4018 offers signal conditioning, A/D conversion, ranging and RS-485 digital communication functions. The module protects your equipment from ground loops and power surges by providing opto-isolation of A/D input and transformer based isolation up to 3000 V DC . The ADAM-4017/4018 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 translated into engineering units. When prompted by the host computer, the module sends the data to the host through a standard RS-485 interface.
