ADAM-4018+
8-channel Thermocouple Input Module with Modbus

ADAM-4018+ Introduction

The ADAM-4018+ is a 16-bit, 8-channel analog input module that provides programmable input ranges on all channels. These modules are an extremely cost-effective solution for industrial measurement and monitoring applications. 3000 VDC optical isolation between the analog input and the modules protects the modules and peripherals from damages caused by high input voltages.
