Voltage-current / RS485 input module PZ-8I is an input module with ModBUS RTU interface for 8 analog voltage or current signals in the ranges ± 2.5 Vdc, ± 10 Vdc and ± 20 mA with 16 bit resolution. The module’s auxiliary power supply can power all 8 current loops simultaneously. The current input with internal shunt can be selected via dip-switch.
The insulation of the inputs with respect to the remaining low voltage circuits is 1,500 Vac.

Applications:
PZ-8I digitizer is applied in all situations in which it is necessary to interrogate various analog instruments with 4-20mA output and provide a digital signal at the output. Its characteristics allow it notable applications, both in industrial and in geotechnical and structural fields such as: dams, bridges, tunnels, monuments, buildings for civil homes, buildings of historical interest, flow and weather measuring sensors, etc.
In other words, we can state that the Digitizer is used whenever there are problems, both operational and economic, in providing for the tensioning of the cables (which can also be in a significant number) and in the various intermediate connections. PZ-8I instead allows the connection to be made using a simple serial transmission cable.
