Carlo Gavazzi power control products

1 - Current / Voltage / Phase Loss monitors (sensors) - Replacements for Electromatic
2 - Timers (programmable timers, On and Off delay timers)
3 - Single loop Temperature controls
4 - PLC controllers
5 - Photoelectric sensors
6 - Dupline
7 - Energy Management
8 - Limit switches

Carlo Gavazzi offers a comprehensive range of monitoring controls for monitoring of phase loss, incorrect phase sequence, phase unbalance, over/under current, over/under load, over/under frequency, and over/under voltage. Easy replacement for Electromatic products.

These monitors are used in a wide range of applications for protecting motors against the damaging effects of single phasing and overloads (elevators, compressors, pumps, air conditioning systems, mixing tanks)

    Photo electric sensors.jpg (18475 bytes)

    Carlo Gavazzi offers a large range of photoelectric sensors which are used extensively on packaging machinery, automatic door systems, and in car washes. Our sensors are available in diffuse reflective, background suppression, retro-reflective, polarized, and through beam. We also offer a range of fiber-optic type sensors for applications where a conventional sensor cannot be used (space restrictions, temperature, atmosphere).

    Also included in our range of photoelectric sensors, is our VP series optical types. These are ideal for use in level applications. They are available in various housing materials which allow their use in various industrial cleaning solutions.

    DuplineŽ - the versatile bus for Industrial Applications and Building Automation. Dupline is used for transferring analogue and digital information over distances up to 10 km. It can be used stand-alone or as part of a PLC based control system. There are no special protocols to learn - all modules are simply and quickly configured with a small hand-held device.

    See also:



    Dupline is used extensively in mining (ventilation, lighting, and conveyor control), elevators (for signal transmission), irrigation systems, water treatment facilities (signal monitoring, control), facility alarm systems, and in building automation (temperature and lighting control, security).

    Energy Management

    The nature of our voltage mains has changed greatly in the last 10 years. With the proliferation of non-linear loads such as inverters, power converters, switch-mode power supplies, and computers, there is a growing concern for the quality of our power sources.
    Problems often arise which can cause equipment failure or shutdown resulting in significant costs and loss of production. Power quality problems can result in failure of compensation capacitors, tripping of fuses, over-heating of transformers and motors, failures of electronic equipment, and high neutral currents.

    Energy costs are becoming a significant expense in most processes. With increased energy unit costs, decreased generating capacity, and the environmental concerns with the burning of fossil fuels, it is important that companies reduce their electrical consumption.


    Carlo Gavazzi offers a broad range of power quality meters and transducers which give early warning of power quality problems - allowing preventative action to be taken before a major failure results. Most of our products offer relay outputs that can be used to immediately shut down a piece of equipment if a certain threshold is reached. Another option is to connect to your PLC or PC control system to provide plant wide monitoring of power quality using 4-20 mA current signals or via RS485 communications.

    Carlo Gavazzi also offers a number of software products for monitoring of a network of meters and transducers. This allows at-a-glance viewing of your complete power system.
