Modbus sensors communication module 4001

The module 4001 is compatible with all the sensors Modbus RS485 from PONSEL according to the following offer : sensor OPTOD (dissolved oxygen/ Temperature), NTU (Turbidity Nephelometric), C4E (conductivity/salinity), pHEHT (pH, Redox, Temperature). The bus RS485 must be linear and is guaranteed functional on a maximal distance of 1km with a cable in pair twisted armored (type AWG26 for example). In the case of an installation with several Module 4001, it is advised to install a resistance of 120Ω At the end of line RS485 (between the signal A and B of the last Module). In case of disturbances on the line Modbus, a repeater RS485 can be necessary.
