The M-7000 series is a family of network data acquisition and control modules that support Modbus RTU and DCON protocols. With the Modbus RTU protocol, the modules can easily communicate with most popular SCADA/ HMI software packages and PLC's. It has the same form factor as the I-7000 series.
The M-7018 is an 8-channel Analog Input module that provides current and voltage input, as well as thermocouple input. The M-7018 also features 4 kV ESD protection and 3000 VDC intra-module isolation. The specifications for the M-7018 are the same as the I-7018, but additionally supports the Modbus RTU protocol as well as the DCON protocol. The input range is selected per module (i.e. all channels are set to the same input range)
