⻬ True RMS Measurement 
⻬ Isolation 
⻬ 0 to 1 mA and 4 to 20 mA
Outputs Available
The OM9 Series transducers 
convert ac currents and voltages to 
dc process signals for direct 
connection to data acquisition and 
recording systems. The OM9 
employ true RMS measurement 
techniques in conditioning the ac 
signal. True RMS measurement 
provides accurate readings for 
signals which contain harmonic 
distortion. For measurement of 
currents and voltages greater than 
listed, the OM9 are directly 
compatible with OMEGA 
instrument transformers.
