Special controls encompass a range of niche monitoring devices tailored for unique industrial applications that fall outside standard relay functions. These include specialized pump controllers, custom logic modules, and environmental sensors designed to interface with power distribution systems. These units are often specified for proprietary machinery or legacy system upgrades where standard monitoring parameters are insufficient to cover specific operational risks.

Transformers and transducers are foundational to power monitoring as they scale high voltage and current levels down to safe, measurable signals. Current transformers (CTs) and potential transformers (PTs) provide the isolation and accuracy required for metering and protective relaying. Our transducers convert these electrical parameters into standard industrial signals such as 4 to 20mA or 0 to 10VDC, allowing for direct interfacing with Programmable Logic Controllers (PLCs) and building management systems.

Alternating relays are utilized in duplex and triplex pumping or compressor systems to equalize the runtime between multiple loads. By alternating the lead motor during each successive cycle, these relays prevent uneven wear and extend the service life of the mechanical equipment. These units are available in various configurations to support lead lag logic and failover protection in the event of a primary pump failure.

Current monitors provide a high degree of protection by sensing the amperage drawn by a load. They are used to detect mechanical jams, belt breakages, or bearing failures by identifying abnormal current consumption. These monitors feature adjustable trip points and time delays to ignore transient inrush currents during motor startup while providing rapid response to sustained fault conditions.

Voltage and phase monitoring controls offer comprehensive protection for three phase equipment. These devices monitor for phase loss, phase reversal, and phase unbalance. Detecting a phase reversal is critical during installation to prevent motors from rotating in the wrong direction, which could cause immediate mechanical damage. Our controls provide clear status indicators and adjustable sensitivity to suit different load characteristics.

Universal voltage relays offer maximum flexibility for maintenance teams and system designers by supporting a wide range of input voltages within a single unit. When paired with digital timing logic, these relays allow for precise control over power up sequences and delay functions. The digital interface ensures repeatable accuracy that exceeds traditional analog potentiometers, making them ideal for high precision industrial processes.

Transportation circuit breakers are specifically engineered for use in mobile environments such as rail, marine, and heavy trucking. These breakers are designed to withstand high vibration, mechanical shock, and extreme temperature fluctuations. They meet specialized industry certifications to ensure reliable circuit protection in applications where standard industrial breakers might fail due to environmental stress.

3 Phase monitors are dedicated protection units for industrial power systems. They monitor the entire three phase power supply to ensure all phases are present and balanced. An unbalance in a three phase system can lead to excessive heat in motor windings and eventual insulation failure. Our 3 phase monitors provide an automated disconnect to prevent this damage, ensuring the integrity of the motor fleet.

The accessories category includes specialized mounting hardware, sockets, and testing equipment produced by Time Mark. These components are designed to facilitate the rapid installation and maintenance of the entire power monitoring line. High quality sockets ensure secure electrical connections and easy replacement of plug in relays, reducing mean time to repair (MTTR) in critical facilities.
