I-7018(R)
M-7018(R)
The I-7018/M-7018 is an 8-channel Analog Input module that provides
current and voltage input, as well as thermocouple input. The I-7018R/
M-7018R is an upgraded version of the I-7018/M-7018 that includes an
extremely high-quality protection mechanism where the overvoltage
protection can be as high as 240 Vrms. The I-7018R/M-7018R is more
suitable for critically harsh environments, and the newly-added open
thermocouple detection feature makes the I-7018R/M-7018R more attractive
than ever. The I-7018/M-7018/I-7018R/M-7018R also features 4 kV ESD
protection and 3000 V
DC
intra-module isolation. The specifications for the
M-7018 and M-7018R are the same as the I-7018 and I-7018R, but provide
additional support for the Modbus RTU protocol as well as the DCON
protocol.
