Product Overview
Macromatic offers a wide variety of AC & DC current sensing relays (sometimes referred to as current monitor relays). They be used in several applications where protection of sensitive or expensive equipment against over or under current conditions is required, such as detecting (sensing) conveyor jam-up conditions, machine tool wear, no load conditions or monitoring status of heater or lamp loads. An external current transformer may be used to extend the range of these products (for more information, read our KnowledgeBase Article).
