G201 is an acquisition module for all types of analog instrumentation, designed to be used in geotechnical, structural and environmental monitoring. G201 can read different types of sensors with different signal types (4/20mA, mV/V, V) and all the vibrating wire instruments. It is also possible to read thermistor sensors as Pt100 and NTC. G201 is available in four versions: 4, 8, 12 and 16 channels. Each channel has one four poles terminal block which can be used to power the transducer and to receive the analog signals. The function of the 4-pole terminal block changes depending on with the type of the instrument connected to it. In case the transducer has only two wires (such as some 4/20mA, Vibrating Wire and the NTC sensors) each individual channel can be configured to read two instruments. For example, a Vibrating Wire sensor and its temperature values can be read on the same channel. In fact, each channel can be considered double and a 16 channels multiplexer can actually be used to read 32 instruments, if the types of sensor allows it. So, G201 can become 4+4, 8+8, 12+12 and 16+16 channels.
