Red Lion extends PAX2C PID control by adding FlexBus support

April 13, 2015
New FlexCard Modules Enable Monitoring and Control of Multiple Applications on Single Display

Red Lion Controls announced the integration of FlexBus technology to its PAX2C proportional-integral-derivative (PID) controller portfolio. By inserting field installable FlexCard modules, users can now populate PAX2C PID controllers in more than 150 configurations to monitor and control multiple application processes on a single display.

Red Lion's advanced PAX2C modular platform provides an easy upgrade path that enables integrators and panel builders to reduce inventory requirements while increasing application support. The solution is ideal for temperature, flow and pressure control in industries such as packaging, plastic welding, extrusion and food and beverage.

The new FlexCard modules include:

  • Process Input/Remote Setpoint Cards: support input of 0/4 to 20 mA to enable cascade control loops where tighter control is required
  • Heater Current Monitor Cards: provide heater current input and can signal when the heater or heater control devices have failed before damage occurs

Red Lion's Crimson programmed PAX2C PID controllers are dual-line displays that change color based on process status, alerting when a value is out of a specified range. With universal process inputs and AC/DC power input, PAX2C controllers accept DC current, DC voltages, process signals, thermocouples and RTD inputs to provide an all-in-one platform that eases integration. Additional features include a large LCD display with easy-to-read bar graphs, programmable annunciators, up to 16 alarms and a built-in USB programming port.
