M-2018-16
16 Channel Differential Analog Input Module with Thermocouple, Voltage and Current inputs. Communicable over Modbus RTU Protocol.
Features
ICP DAS USA’s M-2018-16 is an analog input module that is equipped with 16 differential analog input channels. The M-2018-16’s voltage input range can be 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. Overvoltage protection of up to 120 VDC is provided. The M-2018-16 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.
