I-7018R 电路高保护，支持断线开路检测功能！！

 I-7000 and M-7000 remote I/O modules provide cost-effective protection and conditioning for a wide range of valuable industrial co*ol system. The product line includes sensor-tocomputer, computer-to-sensor, digital I/O, timer/counter, RS-232 to RS-485 converter, USB to RS-485 converter, RS-485 repeater, RS-485 hub and RS-232/422/485 to Fiber Optics. I-7000 supports DCON protocol, and M-7000 modules support Modbus RTU and DCON protocols. Many SCADA/HMI software and PLCs support Modbus RTU protocol. It is easy for them to integrate with M-7000 modules

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 mechani* where the overvoltage protection can be as high as 240 Vrms. The I-7018R/M-7018R i*ore 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 i*a-module isolation. The specificati* 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.   模拟量输入     输入通道 8差分   输入类型 热敏电阻   热敏电阻  +/-15 mV, +/-50 mV, +/-100 mV, +/-500 mV, +/-1V, +/-2.5V, +/-20 mA（需外部接125Ω电阻）热电偶( J, K, T, E, R, S, B, N, C, L, M)       分辨率 16-bit   采样率 10次/秒   精度  +/-0.1% of F.S.R.   带宽 15.7 Hz   零点*移 +/-10 μV/°C   跨度*移 +/-25 ppm/°C   波特率 15.7 Hz   共模* 86 dB min.   差模* 100 dB   输入阻* >400k Ω   过压保护 240 Vrms   热电偶开路检测 √   ESD保护  +/-4 kV (连接到没一个通道)   隔离电压 3000 VDC   接口     接口 RS-485   格式 N, 8, 1   波特率 1200 ~ 115200bps   LED显示     1路LED作电源/通讯指示用   电源     输入 +10 VDC ~ +30 VDC   功耗 1.8 W   工作环境     工作温度 -25 °C ~ +75 °C   存储温度 -40 °C ~ +85 °C   湿度 10 ~ 95% RH, 无冷凝
