Overview:
Red Lion’s advanced PAX^®2C PID controllers offer universal inputs, including thermocouples, RTDs, process signals, DC current/voltage and resistance, to provide an all-in-one platform that simplifies integration. Available in 1/8 DIN size, PAX2C controllers work with both FlexCard™ and standard field-installable PAX option cards to seamlessly support changing applications.

Display:
With a dual-line, tri-color display, PAX2C PID controllers offer six digits on the top row, nine digits on the bottom row and a graphical bar chart. The display is comprised of seven zones which may be configured independently to provide visual indication of control and/or alarm status. The easy-to-read display offers 18 mm character height on the top row, with 8.9 mm character height on the bottom row. The front panel is NEMA 4X/IP65 rated for ingress protection.

Inputs:
PAX2C controllers feature universal inputs to handle various input signals including temperature, process signals, DC voltage, DC current, and resistance. Additionally, a built-in mini-USB port for programming allows the controller to be programming without changing communication cards.

Field-Installable Option Cards:
The PAX2C platform supports the installation of up to three option cards. This allows users to configure the controller for present applications, while providing an easy upgrade path for the future. In addition to enabling additional communications such as RS-232, RS-485, DeviceNet™ and PROFIBUS®, the plug-in option cards also support dual/quad relays, quad sinking/sourcing, heater current monitor and linear DC outputs.

FlexCard Modules:
The PAX2C platform also supports the use of FlexCard modules that allow a single controller to be populated in more than 150 configurations to monitor and control multiple application processes from a single display. FlexCard modules can be installed in any open PAX2C slot to allow the controllers core capabilities to be easily modified to incorporate a heater current monitor, a second analog input and an additional PID controller. The second PID controller allows the PAX2C to control multiple processes from a single display reducing inventory requirements and saving time, money and installation space.

Performance:
PAX2C controllers offer up to 16 alarms and may be configured to meet a variety of control and alarm requirements. Alarms may be programmed to monitor and/or actuate outputs as well as change display colors. The controller provides a max and min rate reading memory with programmable capture time. The capture time is used to prevent detection of false max or min readings that may occur during start-up or unusual process events. Power input is universal and accommodates 50 to 250 VAC /21.6 to 250 VDC.
