Single & Dual Channel Controllers

Single and dual channel controllers combine ease of use and accurate operation for critical temperature and process applications. Advanced models feature large, dual 4-digit displays, PID control for heating and/or cooling, fuzzy logic control, dual output/dual alarm protection, NEMA 4X front panels, ramp/soak programming, digital communications and configuration software.

300B Temperature Controller

The 300B is rugged, reliable and very economical for precise process control. The open board 300B mounts to the subpanel, and has a remote dial for front panel mounting. The 300B has a 10Amp NO relay contact. Switching 2400W at 240Vac, single phase allows the 300 Series to directly control a small strip or cartridge heater... eliminating the expense and the cost of buying and wiring a contactor.

300D Temperature Controller

The 300D is rugged, reliable and very economical for precise process control. The fully enclosed 300D can be either mounted directly to the surface or DIN rail mounted. The 300D has a 10Amp NO relay contact. Switching 2400W at 240Vac, single phase allows the 300 Series to directly control a small strip or cartridge heater... eliminating the expense and the cost of buying and wiring a contactor.

1020 DIN Rail Mount Temperature Controller

The 1020 DIN rail temperature & process controller is the latest addition to the Chromalox 20 Series controller line. This new controller is cost effective, easy to install, extremely fast to configure and comes equipped with the most desirable standard or optional advanced control features. The 1020 offers a bright OLED text in icon matrix display, 3 LED output/event indicators, 3 tactile input buttons and it occupies only 0.9" (22.5mm) of width on the DIN rail. Controller design choices include 2 or 3 outputs, Modbus RTU/RS485 digital communications and standard or low supply voltage choices.

2110 1/4 DIN Temperature Controller

The Chromalox 2110 Temperature controller offers simple setup, flexibility and control features in an attractive, compact design that both OEMs and users will find cost effective. The 2110 is housed in a rugged, plastic 1/4 DIN package that only requires four inches behind the mounting surface. Straightforward operation and easy-touse control features are major strengths of the 2110 controller.

3204 1/32 DIN Temperature Controller

The 3204 control provides full auto-tuning PID control in a compact 1/32 DIN package, making it an excellent choice where panel space is a premium. The large 4-digit display, several temperature and process control options, a rugged design and efficient programming capabilities make the 3204 ideal for use in several demanding applications such as plastics, packaging, heat treating and life sciences. Input options include 9 different thermocouples, 100 ohm Pt RTD or 0-20 or 4-20 mV or mA linear process.

Each of the two outputs can be programmed as heat control, cool control or alarm output. Select from Relay and SSR Drive output combinations. The 3204 also offers either RS-232 or RS-485 Modbus/RTU communications for remote management needs. Auto tuning functions calculate dependable PID parameters for optimal control of the process. The single ramp to setpoint feature enhances process control capability. NEMA 4X/IP66 front panel withstands harsh environments and applications where the unit might come in contact with water or corrosives.

ETR-3400 1/32 DIN Temperature Controller with Smarter Logic®

The ETR-3400 with Smarter Logic offers extensive features that are rarely available on a 1/32 DIN controller. In addition to universal field selectable inputs, auto tuning of PID parameters and a selection of various control outputs, this controller has an additional analog input and an event input, an analog output or digital communications and other software features which make this controller a stand out among 1/32 DINs.

4040 1/4 DIN / 6040 1/16 DIN / 8040 1/8 DIN Temperature & Process Controller

Whether you have to manage temperature, flow, valve positioning or pressure, the Chromalox 40 Series Temperature and Process Controllers provide you with a comprehensive feature list and the flexibility to meet your most demanding process needs. Application needs change over time, but that doesn't mean that you'll need to change your controller. The Chromalox 40 series modular card design provides the owner with the flexibility to alter the functionality with ease. Expansion from 1 to 3 outputs, as well as communications and remote setpoint is easily accomplished and automatically recognized by the firmware. The optional ChromaWare™ configuration software allows the owner to program multiple units efficiently and store parameter settings for later use. The 40 Series Controllers are an ideal complement in both design and aesthetics to its cousin, the Chromalox 50 Series Limit Controllers.

4081 1/4 DIN Advanced Process Controller (Single Loop)

The Chromalox 4081 (Single Loop ) and 4082 (Dual Loop) are affordable temperature and process controllers with advanced functionality including profiling and data-logging options. They both incorporate a graphic/text LCD display and are designed to improve user efficiency with many features integrated to reduce startup time, simplify operation and minimize downtime.

4082 1/4 DIN Advanced Process Controller (Dual Loop)

The Chromalox 4082 is an affordable 2-channel temperature and process controller with advanced functionality including profiling and data-logging features and cascade, ratio, and valve motor drive control methods. The 4082 incorporates a graphic/text LCD display and is designed to improve user efficiency with many features integrated to reduce startup time, simplify operation and minimize downtime.

6020 1/16 DIN / 8020 1/8 DIN Temperature & Process Controller

The 20 Series 1/16 and 1/8 DIN temperature controllers are cost competitive, extremely fast to configure and offer the most common process controller features.  They have 2 or 3 outputs (SSR Drive or Relay), large dual 4-digit LED displays and occupy only 2.6” (67mm) behind the panel. Options include Modbus RTU/RS485 communications and low voltage supply. These units are pre-programmed with the most common parameter value settings found in heating applications.  This allows you to be up and running in less than 60 seconds. The 20 Series also offers an extremely intuitive Configurator program which facilitates the cloning of multiple controllers and fast parameter file uploads and downloads to and from the controller and PC. The program features a six-step Setup Wizard which covers the most basic wiring, input type and programming requirements to assist the less experienced control users.
