FAQs

What is the standard pickup voltage for Thomas & Betts Memphis Coil relays?

The standard pickup voltage is 70% to 110% of the rated coil voltage. For example, a 24VDC coil should activate between 16.8V and 26.4V. Most units activate reliably at 80% of rated voltage under normal conditions.

My relay is not picking up. Could it be a voltage issue?

Possibly. First, measure the voltage at the coil terminals using a calibrated multimeter. If its below 70% of the rated voltage, the issue may be upstream (e.g., voltage drop in wiring, undersized supply). If voltage is within range but the relay still doesnt activate, the coil may be damaged or contaminated.

Can I use a higher voltage than rated to ensure pickup?

No. Exceeding the maximum coil voltage (110% of rated) can cause coil overheating, insulation breakdown, and permanent failure. Always operate within the specified voltage range.

How do I test pickup voltage without a specialized tester?

Use a variable DC or AC power supply with a digital voltmeter. Slowly increase the voltage while monitoring the relays contact state (use a continuity tester or multimeter in beep mode). Note the voltage at which the contacts close thats the pickup voltage.

Is pickup voltage affected by temperature?

Yes. Coil resistance increases with temperature, which can slightly raise the pickup voltage. Thomas & Betts coils are designed to compensate for this within -40C to +85C. For extreme environments, request the thermal derating curve for your specific model.

How often should I check pickup voltage?

For critical applications, perform a pickup voltage test every 6 months. For standard industrial use, annual testing is sufficient. Keep a log to detect gradual drift, which may indicate aging or contamination.

Do Thomas & Betts relays have a shelf life?

Yes. If stored in a dry, climate-controlled environment (under 40% RH), coils can remain functional for up to 10 years. Moisture exposure or extreme heat can degrade insulation and alter pickup characteristics. Always inspect for discoloration or odor before installation.

Can I replace a Memphis Coil relay with a competitors model?

Technically, yes but not recommended. Thomas & Betts coils are engineered for specific inductance, thermal mass, and contact dynamics. Substituting with a non-compatible relay may result in false tripping, contact welding, or system failure. Always use OEM replacements.

What warranty does Thomas & Betts offer on Memphis Coil relays?

Standard warranty is 3 years from date of installation or 5 years from date of manufacture (whichever comes first). Coverage includes pickup voltage drift beyond 5%, coil burnout due to manufacturing defect, and contact failure under rated load.

How do I find the batch number on my relay?

The batch number is laser-etched on the side or base of the relay housing. It typically begins with MC followed by 6 digits and a letter (e.g., MC123456A). This number is required for warranty claims and technical support.

Can I get a copy of the pickup voltage test procedure?

Yes. Download the official Memphis Coil Pickup Voltage Test Protocol (Document

MC-TP-004) from the support portal. It includes diagrams, calibration requirements, and safety guidelines.

What should I do if I suspect a batch recall?

Contact customer support immediately with your batch number. Thomas & Betts maintains a real-time recall database and will notify you if your unit is affected. Recalled units are replaced free of charge, even outside warranty.

Are there software tools to monitor pickup voltage remotely?

Yes. Thomas & Betts offers the CoilSense IoT Module, which attaches to the relay and transmits real-time coil voltage, temperature, and activation status to a cloud dashboard. Available for retrofit on most Memphis Coil models.

Why is pickup voltage higher in my new relay than in the old one?

This is normal. New coils have lower contact resistance and cleaner internal surfaces, which can result in slightly higher pickup voltage. As long as its within the 70110% range, the relay is functioning correctly. Over time, minor oxidation may lower the pickup voltage slightly this is expected aging.
