For more than 50 years, ATC Diversified Electronics, a division of Marsh Bellofram Corporation has offered some of the industry’s highest reliability AC current monitors, motor and pump protection, isolated switches and alternating relay products.
As a leader in solid state control products, the division was the industry pioneer in the first Phase Monitor Relay designed to protect 3-phase equipment from adverse conditions such as Phase Loss (single phasing), Under Voltage (brown-outs), and Phase Reversal (improper sequence). Continued investment in new product R&D and continuous quality improvements allows the ATC Diversified team to offer market-leading technologies, keeping pace with the needs of an evolving industrial marketplace.
Products are available with some of the industry’s shortest lead times.
An alternating relay is a type of electrical relay used primarily in applications where two or more loads (typically motors or pumps) need to be operated alternately rather than simultaneously. This type of relay helps to balance wear and tear, extend equipment life, and maintain energy efficiency. An alternating relay switches the load output between two (or more) devices each time the control signal is activated (e.g., from a float switch, pressure switch, or control contact)...

Marsh Bellofram current monitoring relays, available in multiple styles and types, are designed to detect AC and DC over and under current conditions, effectively detecting and preventing electrical shorts conditions and motor jam-ups which can damage equipment and significantly hamper its longer-term performance...
Pump level controls are often employed within municipal water, wastewater and sewage treatment plants, to ensure smooth-running processes and carefully monitored current loads. Marsh Bellofram offers a rugged series of duplexers, triplexers and quadraplexers, designed to ensure equal run time of loads on industrial pumps, motors and related equipment, extending the useful ...
Available in DIP switch selectable socket mount (plug-in) or DIN-rail mounted versions, Marsh Bellofram time delay relays (also known as TDRs or timers) are used to equip industrial machinery, conveyor belts, exhaust fans, heating systems, lubricators, and pump and motor controls with timed sequence delay, soft-start delay or auto-start functions for added machinery and equipment protection.
Power Alerts are designed to reduce the risk of electrical arc flash by pre-verifying the electrical isolation from outside of a control panel.
HVAC Electrical Protection Products are specialized devices and components designed to safeguard heating, ventilation, and air-conditioning systems (HVAC) from electrical faults, overloads, and transient events. By isolating, interrupting, or diverting fault currents and surges, these products help ensure safe, reliable operation and prolong equipment life. Including: Compressor Proteciton, Phase Monitoring, Voltage Monioring, Timers, Time Delay Relays
A seal-failure alarm relay is a specialized monitoring relay used primarily on pumps (and sometimes compressors) to detect loss of seal integrity—i.e. when a mechanical seal begins to leak. By continuously comparing a sensor signal against a set threshold, it trips an alarm (or even a shutdown interlock) the moment fluid escapes past the intended seal barrier.
SENSERT™ is a remote, cloud-based process monitoring and alert system. A variety of sensors, such as temperature, humidity, vibration, and pressure, can be used for this process monitoring. The sensors can be hardwired directly to the SENSERT Base Unit or wirelessly connected via the SENSERT Remote I/O. The Remote I/O then communicates sensor data to the Base Unit via Bluetooth Mesh. Up to 5 Remote I/O’s can be wirelessly linked to a single Base Unit. Sensor ...
