HIT-2A Rate Indicator Totalizer

Product catalog summary

Overview: The HIT-2A is a versatile rate indicator and totalizer designed for various power inputs including DC, AC, loop, or battery. It features a 5-digit rate display and an 8-digit totalizer, with optional loop-powered 4-20mA output.

Power Supply Options:

Battery Powered: Comes with two C-size lithium batteries.
DC Power Input: 8 to 30 VDC, less than 4 mA, with reverse polarity protection.
AC Power Input: Universal 100-240 VAC at 0.15A, 50/60 Hz.

Display Features:

Rate Display: 5 digits, updates every two seconds, with selectable descriptors (/MIN, /HR, /DAY).
Totalizer Display: 8 digits with selectable descriptors (GAL, LIT, FT3, M3, BBL).
Low Battery Warning: Displays when approximately 10% power remains.

Outputs:

Pulse Output: Opto-isolated open collector transistor, user-selectable pulse duration and rate.
Alarm Output: Configurable for rate or total, opto-isolated open collector transistor.

Environmental Specifications:

Operating Temperature: -4°F (-20°C) to +158°F (70°C).
Humidity: 0-90% non-condensing.

Accuracy and Inputs:

Accuracy: 0.01% reading, ±1 count.
Magnetic Pickup Input: Frequency range 0.2 to 5000 Hz.
Opto-Isolated DC Pulse Input: Frequency range 0 to 5000 Hz.
Contact Closure Input: Internal pullup resistor, high and low logic levels specified.

Additional Features:

20 Point Linearization: Allows entry of up to 20 frequencies with corresponding K-Factors for improved accuracy.
Analog Output Option: 4-20 mA output, reverse polarity protected.
Approvals: Optional CE approval, ISO 9001 certified quality system.

Accessories: Includes spare battery options and universal power supply. Mounting options for explosion-proof enclosures are available.

Model Configuration: The HIT-2A model number includes options for enclosure style, input power, loop-powered analog output, additional options, mounting, and special features.
