Module RS-485 DCON & Modbus RTU 8 kênh đầu vào tương tự M-7018R-G CR
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 VDC 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.
