Product Description

The JM21FA-RMS by J&D is a Hall effect current transducer, sometimes referred to as a 4-20ma sensor due to it’s 4-20ma output signal. The JM21FA is designed to accurately sense AC Amps.

Using a split core design this Hall effect current transducer offers many benefits and can be used in a variety of applications. Built for the measurement of AC waveform currents, utilizing galvanic isolation between the primary circuit (power) and the secondary circuit  (measurement). 0-5V DC, 0-10V DC, 4-20mA DC output proportional to the RMS value of the primary current.

Main characteristics
• Current transformer and RMS circuit in a single case
• Choice of primary current ranges: 5 to 250A RMS
• Output: 4-20mA
• Accuracy: <2% of nominal primary current
• Bandwidth: 50/60 Hz

Applications
• Automation and supervision
• Safety and condition monitoring
• HVAC & pumps
• Refrigeration
