Dataforth's RTD/Potentiometer Module
MAQ20-RTD31 industrial data acquisition and control system features an analog resistance input module designed to provide good channel protection. It interfaces to three types of 3-wire sensors: 100 Ohm Pt and 120 Ohm Ni RTD (resistance temperature detectors), and potentiometers up to 5 kOhm. The module has six input channels, each of which is protected up to 240 Vrms continuous overload in case of inadvertent wiring errors. To be sure data integrity is preserved, overloaded channels do not adversely affect other channels in the module.
