M-2018-16
Introduction
The M-2018-16 is a 16-channel differential analog input module supporting voltage, current, and thermocouple inputs. Voltage input ranges from ±15 mV to ±2.5 V, current input supports 4–20 mA, 0–20 mA, or ±20 mA, and thermocouple types include J, K, T, E, R, S, B, N, C, L, M, and LDIN43710. Each thermocouple channel is equipped with open-wire detection.
For protection, the module provides 120 V VDC overvoltage protection, EMS (EFT/ESD/Surge) protection, and 3000 VDC I/O isolation, ensuring strong noise immunity and reliable performance in demanding industrial environments.
