The modules are factory calibrated to allow the XR440, or XR450, pocket logger to accept a wide range of different voltage and mA current input signals. Each individual input channel can be configured for the following:- -5 to +5vDC, 0-10vDC, 0-20vDC, 0-30vDC, 0-60vDC, 4-20mA (also 0-20mA) or the standard 0-5vDC suitable for all Pace Scientific sensor inputs. Modules plug directly ...
