PACs, PLCs, PID & Controllers

The topic of PACs and PLCs + other controllers, covers a large range of product type as seen below.

PACs represent the latest Automation and Control technology, that has many advantages over the traditional PLCs.

Both in Hardware and Software, PACs expand beyond PLCs ability.

There are two levelss- Osless PAC & OS PACs.

However for many projects a PLC is lower cost and a good technical fit for the job.

Hence MasTec offers all levels of PACs and PLCs to choose from.

For dedicated control, like ovens, furnaces etc, the lowest cost controller is the PID Controller in many form factors.

Embedded PACs, PLCs and controllers are also available is programmed by Basic, C, a Proprietary Language running in an OS or OS less environment. This is often a very good choice for Machine building where greater flexibility is required.

The Last technology that is often used is Distributed I/O. This can mean a PLC or PAC driving a set of Distributed IO remote blocks or can be a PC acting as a Soft PAC driving an ethernet or RS-485 network of remote IO blocks. Often a very good solution for simple control and monitoring

There is also a new form of PLC that is extremely low cost that comes in various levels of performance. At the simple level they are a very powerful relay controller with both Analog and Digital Inputs.

These low cost PLCs can be expanded to carry dozens of IO points and can easily interface with Analog systems for control.

Any machine builder that just wants Digital Control could look at these devices as a very quick and low cost solution.
