GL840 Data Logger
數據採集器
Three types of input system enable to measure various phenomena
Input system 1 : Multifunction analog input ports
Contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels. The GL840’s inputs are suitable for combined measurements from voltage, temperature, humidity, logic, and pulse signals.
The standard configuration has 20 analog input channels. It is expandable to 200 channels by adding optional 20 channels extension terminal base unit (B-566) and input terminal units (B-564 or B-565).
