Description
The M-7019R is an analog input module that includes 8 differential analog input channels. Voltage, current, or thermocouple input can be selected for all analog Input channels via a jumper, and each channel can be configured for an individual range. The voltage input range can be from ±15 mV to 10 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 can be used for the thermocouple input.
Up to 8 different analog input types can be connected to a single module. The module provides up to 240 Vrms overvoltage protection, 4 kV ESD protection, and 3000 VDC intra-module isolation also features per-channel open wire detection for the thermocouple and +4 ~ +20 mA input types. The M-7019R supports Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7019R.
