PLCs for Automation, Machinery & Control Panels

PLCs are commonly used in automation systems, machine control, pump stations, water treatment, conveyors, process equipment, alarms, monitoring systems and control panels. They can read inputs from sensors and switches, process logic, and control outputs such as relays, contactors, valves, lights and alarms.

Always check the PLC supply voltage, number of inputs and outputs, input type, output type, communication ports, programming software, expansion options, memory, mounting style and application requirements before ordering.

HMIs for Operator Control & Monitoring

HMI displays are used when operators need to view system status, adjust setpoints, acknowledge alarms, start or stop equipment, view process values or interact with a control system. They are commonly used with PLCs, controllers, sensors, VFDs and industrial communication networks.

Frequently Asked Questions

What is a PLC used for?

A PLC, or programmable logic controller, is used to control machines, pumps, processes and automation systems by reading inputs, processing logic and switching outputs.

What is an HMI used for?

An HMI, or human machine interface, is used to let operators view system information, adjust settings, acknowledge alarms and control equipment through a display panel.

What is the difference between a PLC and an HMI?

A PLC performs the control logic. An HMI provides the operator interface. In many systems, the PLC controls the equipment while the HMI lets the operator monitor and adjust the system.

What should I check before buying a PLC?

Check the supply voltage, input and output count, input type, output type, communication ports, programming software, expansion options and mounting requirements.

Can you help me choose the right PLC or HMI?

Yes. If you are unsure which product suits your application, contact AuscomTech with your control requirements, number of inputs and outputs, supply voltage, communication needs, display requirements and connected equipment.
