PCC-IV Digital Loop Controller

The PCC-IV Digital Multiple Loop Controller, the upgrade for the PCC-III, is a boiler or multiple loop process controller. The PCC-IV has been designed to seamlessly replace the PCC-III in hardware and software designs, with upgraded technology and increased longevity.

  • Dual Modbus Ethernet ports
  • Color Touchscreen
  • USB programming port
  • Larger Blockware memory
  • Modern dual core processor, large memory
  • SD card for easy field firmware upgrades
  • Retentive memory that never wears out (no battery! no EEPROM!)
  • 100% compatible with any existing PCC-III to OIT, SCADA, or BAS communications links with NO Modbus changes required. PC4_Draw AutoConverts PCC-III into PCC-IV.

Overview and Features

Preferred Utilities considers not only the creation of new products, but the support and replacement of older products. With this in mind, we designed the PCC-IV Loop Controller to seamlessly replace the PCC-III when the hardware is too old to function. Look no further than Preferred for upgrades and the next generation of quality technology.

The PCC-IV is a complete control solution for individual boilers or multiple control loops. With upgraded technology and increased longevity, the PCC-IV is also a great replacement for the Siemens/Moore 352 and 353 models (out of production October 2017). With added features and a retentive memory that lasts 5x the lifespan of the Siemens controllers, the PCC-IV is prepared for any application.

Preferred also offers many other products that are fully capable replacements for any loop controller, like our BurnerMate Universal, PWC, and PLC based systems. While each type of controller has specific advantages/disadvantages, Preferred has the in-house control logic engineering, panel fabrication, and field service start-up to provide the best solution for your application.

Designed with the intent to seamlessly replace the PCC-III, the PCC-IV upgrade fulfills everything its predecessor did with additions. The most notable new PCC-IV features include:

  • Dual Modbus Ethernet ports
  • Color Touchscreen
  • USB programming port
  • Larger Blockware memory
  • Modern dual core processor, large memory
  • SD card for easy field firmware upgrades
  • Retentive memory that never wears out (no battery! no EEPROM!)
  • 100% compatible with any existing PCC-III to OIT, SCADA, or BAS communications links with NO Modbus changes required. PC4_Draw AutoConverts PCC-III into PCC-IV.
