Automation & Integration​


At ACA Controls Ltd. we offer the following process design services:

Programmable Logic Controller (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices.

Human-Machine Interface (HMI) is designed for industrial applications. Supervisory Control And Data Acquisition (SCADA) is a system of software and hardware elements that allows industrial organizations to maintain efficiency, process data for smarter decisions, and communicate system issues to help mitigate downtime.

Loop checking is the process that confirms the components wired correctly and also helps to ensure that the system is functioning as designed.

Retrofitting is the practice of upgrading old components with new components, thus creating a more stable system foundation and potentially improving the performance of the machine.

Create a design to control a machine or process.

At ACA Controls Ltd. we have substantial experience in and offer numerous CAD Services:

Drawing that falls between one-line diagrams and wiring diagrams. They are used to show the wiring of instruments and electrical control devices in elementary ladder or schematic form.

Interconnection Diagram is the visual structure of a circuit that displays components used in the circuit to show flow of power and signals between components and  a wiring diagram is a simplified conventional pictorial representation of an electrical circuit. 

specifies the action of an instrument. That is whether the instrument is reverse-acting or direct-acting.

Includes more details than a PFD. It includes major and minor flows, control loops and instrumentation. P&ID is sometimes referred to as a Piping and Instrumentation Drawing. These diagrams are also called flowsheets. P&IDs are used by process technicians and instrument and electrical, mechanical, safety, and engineering personnel.

The equipment layout is the detailing of the conceptual layout. It is the basic document of mechanical engineering design or in other words, this document is the basis for the development of construction drawing by all disciplines.

Are any of these CAD Services something that you’re looking for? Our quality of work and customer satisfaction is, and has always been, above and beyond our client’s expectations.
