DIN Temperature Controllers
Plus (+) Series DIN temperature controllers have plug-in modules for outputs, inputs, alarms, and communications, so that users can keep only one type of controller in stock and adapt it for each application as required. Models include 1/16, 1/8 and 1/4 DIN size units sold under West and Partlow brands. Controllers have dual setpoints that can be selected from a remote location, and PID control with pre-tuning and self-tuning.

Remote Setpoint Improves Control
Remote setpoint is useful in a wide variety of applications. Using this feature, a heat pump can be made to operate in two stages, with a different setpoint for each stage. In a paint booth, remote setpoint may used to adjust the setpoint based on relative humidity. Another example is a production line, where the setpoint can be changed to accommodate changes in setup to manufacture different products.

 

Each “+' Series controller has a communications port that can receive setpoint changes from a remote operator, PLC, or factory control software. The remote setpoint input can be an analog voltage or current or potentiometer setting. In addition, the user can toggle between auto and manual control by a remote digital command or from the front panel.

Lower Installed Cost
The ‘+' Series accepts universal inputs, minimizing stocking requirements.

In addition, users may customize the controllers for a variety of applications using optional plug-in modules for outputs, inputs, alarms, and communications. This will appeal to companies that, until now, have had to stock a wide range of controllers. With the ‘+' Series, companies keep only one type of controller in stock and adapt it for each application as required. The user pays only for the options needed.

Sophisticated Control
DICG's ‘+' Series provides PID control of processes, including pre-tuning and self-tuning. Pre-tune is used on startup and is a one-step tuning algorithm designed to get to setpoint fast. Self-tune – also called adaptive or continuous tuning – is engaged near setpoint to control overshoot and continues to operate as needed thereafter. The controllers can also provide simple on/off control, heat-only mode, and heat/cool mode.

Up to three outputs are available, programmable for control, alarm, transmitter power supply, or retransmission of a process value or setpoint. Alarms can be high/low, deviation, band, or logical. Sensor break detection is also provided.

A new feature on the 1/8 and 1/4 DIN ‘+' Series controllers is a transmitter power supply option.
 
Simple to Use
The ‘+' Series controllers provide for the auto-detection of hardware modules, and require no link jumpers. These combined features alone are estimated to reduce setup time and decrease the risk of setup mistakes by as much as 50 percent. The auto-detection feature is particularly helpful to systems integrators and distributors who do lots of controller setups, and to end-users upgrading in the field. Because the controllers automatically configure themselves as soon as output cards are fitted, users save valuable engineering time.

A simple keypad on the face of each controller provides for fast, easy setup and program changes. Alternatively, the operator may use an intuitive Windows-based configuration software that steps the user through the setup process. A communications port is dedicated to this purpose (RS-485, Modbus, ASCII protocols.) A security code can be also be used for tamper-proofing to lock out unauthorized operator changes to the controller.

Another benefit of the ‘+' Series platform is a fully customizable operator menu. Using the PC configurator the ‘operator menu' can be tailored to the application – displaying only the amount of information needed thereby preventing operator“information overload”.   Compared to DICG's earlier models, the overall HMI (Human Machine Interface) has also been improved, its larger digits easier to read with the ability to select at point of ordering between red and green displays.

Finally, installation is also simplified by a wide choice of power supply options: 100 to 240V AC (standard) with optional 24V DC (22 to 65V / 20 to 48V AC).
