Features
Introduction
M-7018-16 is a 16-channel differential analog input module that supports current, voltage, and thermocouple input. The voltage input range can be from ±15 mV to ±2.5 V, and 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. Overvoltage protection of up to 30 VDC is provided. The module also features per-channel open wire detection for the thermocouple input types and provides 4 kV ESD protection as well as 3000 VDC intra-module isolation.
