Ordering Information
† Modules can be ordered with other input/output ranges. Consult
factory for ordering details and specifications
Installation Notes:
1.) This Equipment is Suitable for Use in Class I, Division 2, Groups A, B,
C, D, or Non-Hazardous Locations Only.
2.) Warning - Explosion Hazard - Substitution of Components May Impair
Suitability for Class I, Division 2.
3.) Warning - Explosion Hazard - Do Not Disconnect Equipment Unless
Power Has Been Switched Off or The Area is Known to be Non-Hazardous.
NOTES:
(1) For 1 to 25 seconds the max allowable transient current rating is √ 2500 / (event time). For less than 1 second,
ANSI/IEEE C37.90.1 applies with a 0.05 Ω load. For greater than 25 seconds, the 10A max continuous rating applies.
(2) For 10-100% rated span. Add 0.25% accuracy error (-02 thru -07), or 1.00% accuracy error (-01), for 0-10% Span measurements.
Accuracy includes nonlinearity, hysteresis and repeatability but not source or external shunt inaccuracy (if used).
(3) At standard 60Hz factory calibration. Consult factory for calibration at other frequencies.
