The Lakewood Instruments WebNode connects the 2000 series -RS2L option card to Ethernet networks using the IP protocol family and the Transmission Control Protocol (TCP). The WebNode contains a Web (http) server that allows presentation of custom content.

The Lakewood Instruments 2000 Series controllers have many options available to add many different inputs and outputs to the controller. All of these options can be added in the field. There are options for 4-20 mA outputs (35L), Remodte Communications via RS232 (RS2L), Communications via a LonWorks network (2KIN-VI), Conductivity Inputs (NCON), pH/ORP inputs (NpH), Digital Inputs (NDIG), 4-20 mA Inputs (N420I), Relay Outputs (NRLY), Modems and a +24VDC power supply (PS).

These are the cooling tower replacement parts for plumbing assemblies.

Miscellaneous Accessories include the Drum Switch (model DS), the Audio/Visual Alarm (model AV), the Heavy Relay (model HR), the Panel Mount kit (model PM), the Bracket Mount kit (model BM), the external temperature compensator, the pH transmitter, the pH/ORP Simulator, the pH Preamplifier, and the Conductivity Preamplifier.

Miscellaneous Plumbing Accessories include the Corrosion Coupon Rack (model 9050), the Controller Inlet with Shut-off Valve and Sample Cock (model 9102), the Corporation Stop (model 9160), and the Chemical Injection Manifold (model 9176)

The 4-20 mA Input Node (N420I) is a LONWORKS Technology-based node. It contains its own micro-controller which communicates with other LONWORKS nodes on a twisted-pair communication wire. The N420I is a node which may be added to a Lakewood Instruments 2000 series controller to add four channels of 4-20 mA input.

The Conductivity Node (NCON) is a LONWORKS Technology-based node. It contains its own micro-controller which communicates with other LONWORKS nodes on a twisted-pair communication wire. The NCON is a node which may be added to a Lakewood Instruments 2000 series controller to add a conductivity sensor input.

The Digital Input Node (NDIG) is a LONWORKS Technology-based node. It contains its own micro-controller which communicates with other LONWORKS nodes on a twisted-pair communication wire. The NDIG is a node which may be added to a Lakewood Instruments 2000 series controller to add four channels of digital input to the controller.

The pH/ORP node (NpH) is a LONWORKS Technology-based node. It contains its own micro-controller which communicates with other LONWORKS nodes on a twisted-pair communication wire. The NpH is a node which may be added to a Lakewood Instruments 2000 series controller to add either a pH or an ORP sensor input to the controller.

The Relay Node (NRLY) is a LONWORKS Technology-based node. It contains its own micro-controller which communicates with other LONWORKS nodes on a twisted-pair communication wire. The NRLY is a node which may be added to a Lakewood Instruments 2000 series controller to add four additional relay outputs.

The pump accessories include the tubing kits, the rigid suction line, and the wall mount bracket. The spare parts kits are included on this cutsheet.
