How much is your switching solution really costing you

When considering switching solutions, traditional choices for Engineers and Supply Chain Managers are Solid State and Electromechanical technologies. Solid State being a more recent technology is frequently compared to electromechanical in almost every aspect. Engineers, Supply Chain Managers, Marketing and Business Development Managers are often concerned about a variety of costs accruing over the entire life cycle of the equipment where the switching solution is implemented.

Solid State Relay VS Electromechanical Relay

SSR vs EMR

Rather than focusing only on initial cost, the Total Cost of Ownership (TCO) concept offers an approach toward considering the life cycle of the switching solution, where life expectancy is one key feature of SSRs and SSCs, especially when compared to EMRs. The TCO calculator will help you express the "Cost Effectiveness" of SSRs and SSCs quantitatively by identifying known and hidden costs that will negatively impact the profitability of the business.
