Introduction
The M-7018Z is a 10-channel universal analog input module with an RS-485 interface that is specially designed for extremely accurate thermocouple measurement and features automatic cold-junction compensation for each channel to ensure temperature output consistency and stable temperature output in the field. The innovative design of the enhanced model ensures that thermocouple measurement is more accurate than with the earlier design.
Besides the thermocouple inputs, The M-7018Z also supports voltage and current input. The voltage input range can be from ±15 mV to ±2.5 V. Up to 10 different types of Analog Input can be connected to a single module. The module also provides up to 240 Vrms overvoltage protection and features per-channel open wire detection for thermocouple and +4 ~ +20 mA input types. The M-7018Z supports Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7018Z.
