PCT55 – Programmable Logic Controller

 

PCT55 – Programmable Logic Controller

Description

PCT 55 is a programmable logic controller (PLC) with graphical touch screen control panel designed primarily for use with the Armfield EPC series of process control products, but can also be used to control other items.

It is supplied with PID control algorithms implemented in ladder logic and configured to suit each of the EPC processes. The user has full access to all the software and algorithms with the following features:

  • Calibration of the sensors associated with each product, calibration values can be stored in the PLC
  • Specific control exercises written for the four Armfield process units
  • Both proportional analogue and time proportioning discrete outputs
  • Individual Control of P, I & D parameters, re-verting to default parameters for each product on start up
  • User selection of sample time, cycle time, filter weighting
  • The control algorithms are written as separate sub-routines, making it straightforward for advanced users to write and use their own ladder logic control algorithms
  • Control facilities exist for a user defined process as well as the four Armfield process rigs without having to change the programming
  • Freely available programming software for the PLC and touch screen downloadable from the manufacturer’s website.
