ADAM-5018 7-channel thermocouple input module
The ADAM-5018 is a 16-bit, 7-channel thermocouple input module
that features programmable input ranges on all channels. It accepts
millivolt inputs (±15 mV, ±50 mV, ±100 mV, ±500 mV), voltage inputs (±1
V, ±2.5 V), current inputs (±20 mA, requires 125 Ω resistor) and
thermocouple inputs (J, K, T, R, S, E, B).
The module forwards the data to the host computer in engineering
units (mV, V, mA or temperature °C). An external CJC on the plug-in
terminal is designed for accurate temperature measurement.
