"Proud to be the AWT 2011 Supplier of the Year"
Interface: Touch Screen display, 5.7” diagonal viewing area. Display Size: 115x86 mm Pixel: 320x240 Color: TFT 65536 Backlight: LED or CCFL Memory: 16 MB Flash, 16 MB RAM Multiple levels of security Screen is accessed by opening the NEMA 4X enclosure front panel. Relay Outputs (Internal): Six relays rated at 120VAC. Relay ratings, 3 AMP per relay, 15 amps total Chemical feed and additional relay programming methods, available selections Feed by percent of blowdown time after blowdown By Setpoint with Percent of time feature as part of spaced feed for setpoint “creep”. Trace chemistry capable with user definable correction factors as part of programming. By makeup totalized gallons By blowdown totalized gallons Percent on time Scheduled feed by time and day Alarm relay-User selected alarms powered output shall be selectable to either feed chemical or to alarm on the following conditions. Inputs: Up to 8 active Sensor inputs (2 TWR Conductivity, pH and ORP, 2 MU Conductivity) can be ordered in various combinations. Water meters- Two Water meter inputs are standard and be factory or field upgradeable for two additional (Total four) water meter inputs Each relay shall be capable of being configured to operate with either of the two flow (digital) input for activation or deactivation Expansion capabilities: The unit will be factory or field upgraded. Additional expansion features include: 4 Additional Fully programmable relays ( NRLY Nodes) 8 Sensor inputs. Combo of Conductivity using NCON and pH or ORP Probes using NpH/ORP
Nodes. Requires the purchase of additional probes/Plumbing kits. 8 Additional 4-20MA inputs (2 N420I Nodes) 4 Additional Digital Inputs (NDIG Node) Interface/Communications: The NexSys comes standard with the following system interfaces : LON EIA 709 FTT10, BACnet IP and MODbus TCP (As well as Incorporate DMX outputs). The unit shall comes from the factory with all tables and outputs defined for Information being transmitted , including: The state of any installed relay (On/Off) Water meter readings Conductivity reading Any additional sensor reading (ph, ORP) Any sensor alarms Any Additional 4-20mA input readings Any Additional 4-20 mA output reading Flow condition (and any other digital inputs) Remote Communications: The controller has standard Ethernet capability through and HTML interface that allows 100% access to all features and control parameters of the controller. The remote access allows the user to alter, confirm and manipulate 100% of configurations. All features, parameters, settings and functional requirements to operate, program and monitor the controller are accessible from the touch screen and DO NOT require the use of an external input, PC or device to operate or access. The controller will come standard with the capability to send E-service reports to a subscribed service (user to set up account with a service at their discretion). Controller displays operating values, via a color touch screen, color coded graphs for all sensor and relay operation times and readings with time and date stamps. User shall be able to manipulate graph via zoom and scroll features. Approvals Controller must be UL and CSA Listed (ETL listing is acceptable) NEMA 4X enclosure Power: Transformer power ratings of 120/240 VAC 50/60 Hz.
