The NexSys® control system is the latest in a long line of reliable, easy to use controllers from Lakewood Instruments. The NexSys® control system uses the latest in microprocessor technology with a 5.7” color touch screen interface for a high level of application flexibility.
All features, parameters, settings, and functional requirements to operate, program and monitor the NexSys® control system are accessible from the touch screen and DO NOT require the use of an external input, PC or device to operate or access. The NexSys® control system even includes on-board help screens with wiring, programming and maintenance instructions.
The NexSys® control system comes standard with the following system interfaces and DMX outputs: LON EIA 709 FTT10, BACnet IP, MODbus TCP. The unit comes from the factory ready to integrate readings into a BAS, including the state of any installed relay (on/off), water meter readings, conductivity readings, additional sensor readings (ph, ORP), sensor alarms, additional 4-20mA input readings, flow condition and other digital inputs.
The NexSys® control system comes standard with Ethernet capability through a browser (HTML5) interface that allows 100% access to all features and control parameters of the controller.
