4 POINT

4-point modules provide exactly four channels or I/O points within a single module housing, offering a compact footprint for applications where signal density must be balanced against isolation, accuracy, or hazardous-area compliance. Products carrying this tag include Allen-Bradley 1718 and 1719 series intrinsically safe analog modules rated for Zone 1 and Zone 2/Class I, Division 2 environments, Micro800 series plug-in modules such as RTD inputs and relay outputs, and Point 5000 and PointMax XT analog and digital modules. Channel types span HART analog input and output, RTD, thermocouple, relay output, high-speed counter input, and isolated analog output, making 4-point a common configuration across both process instrumentation and discrete control applications.
