SENECA S20N1 and S21N1 batch controllers are cost-effective, simple and safe solutions for process automation. Equipped with polycarbonate front membrane from 72x144 mm with 2 Numeric 5-digit LED high brightness displays, 7 status indicators LED and 6 programming buttons, S20N1 and S21N1 get digital signals from free contact, Reed, NPN, NAMUR, Hall effect and photoelectric sensors.
The units are designed to control the measuring probes and activate valves or motors so to manage metering, batch& blending, filling and regeneration processes for fluids, in an automatic, time-based and accurate way. S20N1 and S21N1 batch controllers can be used as “stand-alone” metering unit or “auto-manual” station. In this second mode, they work as a local control unit in order to manually compensate, integrate or stop metering recipes remotely controlled from the PLC. Flexibility and redundancy of the system, capacity dosing, recipe development, energy efficiency of controlled processes are improved.
