M-7018-16_DESCRIPTION.html
The M-7018-16 is an analog input module designed with 16 differential analog input channels. The voltage input ranges from ±15 mV to ±2.5 V, the current input range can be either +4 to +20 mA, 0 to +20 mA, or ±20 mA, and types J, K, T, E, R, S, B, N, C, L, M, LDIN43710 thermocouple can be used for the thermocouple input. Designed with overvoltage protection of up to 30 VDC is provided. M-7018-16 features per-channel open wire detection for the thermocouple input types, 4 kV ESD protection and 3000 VDC intra-module isolation.
