HVAC USA - H721HC
H721 SERIES & H921 Current Sensors: 4-20mA Analog Output VERIS INDUSTRIES TM Load Trending With 4-20mA Output H921 H721HC DESCRIPTION The Hawkeye 721LC, 721HC, and 921 provide accurate load trending information with a proportional 4-20mA output signal. Preset slide-switches provide easy field setup of sensed amperage range with no need for jumpers. APPLICATIONS Load trending Motor control Fan/Pump Status EXAMPLE LINEAR OUTPUT Scale software as shown 20mA FEATURES Power the sensor, and receive the signal with only two wires...lower cabling and commissioning costs than with traditional 3-wire sensors Self-gripping split-core for fast retrofit installation...no need to remove conductor (H921) Economical solid-core features adjustable bracket for easy alignment (H721) Factory calibrated switch-selectable ranges for high resolution and installation ease Three field-selectable ranges per unit...fewer versions to choose from, stock, and install Removable mounting bracket for installation flexibility Bracket on H921 can be installed in three different configurations... added flexibility 100% solid state, no moving parts to fail 5-year warranty SENSOR OUTPUT 4mA 0A Selected Range* SENSED AMPS *Factory calibrated ranges selected with the amperage range switch Maximize Reliability Minimize Installed Cost current monitoring 5 SPECIFICATIONS Year Warranty Sensor Power Insulation Class Frequency Temperature Range Humidity Range Accuracy Response Time Terminal Block Maximum Wire Size Terminal Block Torque (nominal) UL 508 open device listing; CE: EN61010-1:2001-2, CAT III, deg. 2, basic insulation For applications requiring double or reinforced insulation, please contact the factory. 800.354.8556 +1 503.598.4564 30mA (max)@12-30VDC 600VAC RMS (UL), 300VAC RMS (CE) 50/60 Hz -15° to 60°C (5° to 140°F) 10-90% RH non-condensing ±2% F.S. from 10% to 100% of selected range, but not less than ±0.4A 2 sec. 14 AWG 4 in-lbs (0.45 N-m) www.veris.com HQ0001762.A 01121 800.354.8556 +1 503.598.4564 DIMENSIONAL DRAWINGS H721LC/H721HC Removable/Adjustable Mounting Bracket 0.7" (19 mm) 0.9" (23 mm) 3.0" ** (75 mm) 0.2" x 0.15" slot (2x) 2.8" (68 mm) 3.8" (95 mm) 4.2" (106 mm) 1.1" * (27 mm) * Terminal block may extend up to 1/8" over the height dimensions shown. ** Slide switch may extend up to 1/4" over the height dimensions shown.
