Relays Simplify Systems, Increase Efficiency, and Control Costs

Product packaging uses increasingly complex equipment for inspecting, cleaning, filling, sealing, wrapping, labeling, and palletizing. The industry has introduced more automation with electronic control to increase productivity, quality, and safety. Relays are used to control timing, to protect equipment and to ensure safe machine operation and the wellbeing of the operator.

Macromatic Relays Used For Packaging Equipment:

  • Time Delays Relays have built-in timing to control automated operation.
  • Phase Monitor Relays protect equipment from damage due to voltage faults.
  • Current Sensing Relays monitor and detect over or under current conditions.
  • General Purpose Relays provide economical operation in installations with space limitations.

Common Challenge

Packaging equipment often must work independently as a stand-alone machine, but also operate as an integrated part of a complete automated system. The need to operate as an isolated process creates challenges for machine designers. To accommodate this requirement, engineers often revert to PLC systems so new code can be written and communication protocols can be established.  PLC systems can be problematic:

  • PLCs increase the complexity and cost of systems.
  • Added onsite re-programming is required.
  • PLCs can require increased maintenance and more complicated troubleshooting.

Our Solution

Macromatic offers highly reliable and cost-effective products that are ideal for packaging equipment. By using relays in simple systems, processes can be more efficient and low cost. Integrating these systems into a larger operation can be achieved with simple relay handshaking without costly duplicate control platforms. Macromatic relays are made in Wisconsin, USA, to ensure supply chain integrity.

Relays for Simple, Cost-Effective Control of Packaging Equipment


Macromatic offers a wide variety of time delay relays (sometimes referred to as timing relays or timers). First choose the type of mounting configuration required for your application and then select from a variety of functions, time setting methods & output configurations.


Macromatic offers a wide variety of AC & DC current sensing relays (sometimes referred to as a current monitor relay). These relays are used in applications requiring protection of sensitive or expensive equipment against over – or – under current conditions.


Voltage sensing relays monitor either AC single phase (50-60Hz) or DC voltages to protect equipment against voltage fault conditions. No separate supply (input) voltage is required on any Macromatic voltage monitor relay since each unit is powered by monitored voltage.
