Model HI 2151/30WC -Weight Controller

Product Design
The basic design of the HI 2151/30 has remained the same on all our multipurpose weight controllers to provide an easy upgrade path. Hardy understands the difficulties in replacing a unit and the space limitations on control panels. That`s why we design our products so you can replace an old unit with a new one using the same enclosure cutout.

Display
The six digit alpha-numeric red LED display allows for ease of use in reading weight values as well as reading menus. A 30 segment bar graph is standard and can be programmed for various modes and uses.

Front Panel
The front panel keypad and menus follow the same pattern. The current menus and features have been enhanced, but the front panel keys have remained the same. There is no need to relearn features and functions of an instrument when a new one is installed.

Setpoint Control
The HI 2151/30WC can independently control as many as eight relays based on either net, gross, rate-of-change, peak hold or totalized weight values. Each relay has its own individual preact to compensate for in-flight material, and deadband to compensate for relay chatter.

One Million Counts Of Resolution
The HI 2151/30WC has 1,000,000 counts of resolution yielding better control, accuracy and recording in weighing applications. This is 25-50 times more than the typical weight controller resolution. You can tolerate large dead loads, over sizing of load cells, and still have an bundance of resolution to work with.

C2 Electronic Calibration
C2 enables electronic calibration of the weigh system without test weights. This saves system start-up costs and aggravation.

Waversaver
Waversaver eliminates the effects of unwanted plant vibration on or around the scale by permitting the weigh module to “see” through the unwanted vibration signals - as low as 0.25Hz - while yielding a stable actual reading.

SECURE MEMORY MODULEThe rear panel accessible Secure Memory Module (SMM) automatically protects and stores critical data. It allows this data to be physically transferred from one indicator to another. If a problem occurs, simply remove the current SMM and plug it into a new indicator, and your system will be up in running in minutes.

Standard input power is 120 VAC + / - 10 percent.

Analog Output (-B1)

The Analog Output is configured from the front panel or the serial port and set up by jumpers on the printed circuit card. The option allows the transmission of Gross, Net, Optional ROC, Peak or Total weight as 0-5V, 0-10V, 0-20mA or 4-20mA (or the reverse of these), and makes it possible to span these ranges over a portion of the weight data. Resolution is 16,000 counts, or the number of display counts available in the range selected, whichever is less.

Two analog optional boards can be installed in each instrument. Both voltage and current data are available simultaneously.

Binary Coded Decimal (BCD) Output (-B2)

This BCD Option provides six digits of parallel weight data representing Net, Gross, Tare and the present front panel display. If all types of output data are requested, they will appear one after the other, ten milliseconds apart. The BCD option provides a 37 pin D-subminiature connector on a 6 inch cable.

Binary Coded Decimal (BCD) Output (-B5)

This BCD option provides six digits of parallel weight data representing Net, Gross, Tare and The Present Front Panel Display. If all types of output data are requested, they will appear one after the other, ten milliseconds apart. The BCD option provides a 40 pin connector on a 60 inch cable for use with either the optional - B6 or -B7 external termination boards.

BCD Single Termination Card (-B6)

The BCD Single Termination Card is an optional external interface point for a single BCD port signal line. The card is designed for use with a single HI-2151/30WC-B5 instrument.

BCD Quad Termination Card (-B7)

The BCD Quad Termination Card is an optional external interface point for up to four sets of BCD port signal lines. All terminal positions accept 20 to 26 gauge cable sizes. Additional terminal boards may be interconnected to allow multiple BCD ports to exist in a tri-state arrangement.

Remote I/O (RIO) Interface to the Allen-Bradley Network (-B8)

The RIO port allows bi-directional communications with Allen-Bradley Programmable Logic Controllers (PLC) and Small Logic Controllers (SLC). The HI 2151/30WC represents a quarter rack of discrete I/O (32 bits in the Logic Controllers output and input image files) to the Logic Controller and supports both discrete and block transfers of data. It can support up to 230.4 Kbaud transfer rates.

Binary Coded Decimal (BCD) Output (-B9)

This option provides six digits of parallel weight data representing Net, Gross, Tare and the present front panel display. If all types of output data are requested, they will appear, one after the other, ten milliseconds apart. This option provides a 24 inch cable for use with the HI 2151/30WC-WS wall mount controller.

Profibus Interface Option (-B12)

Allows bi-directional communications to Profibus (Process Fieldbus) products including those made by Siemens, GE Fanuc and Texas Instruments. This interface supports PROFIBUS-DP (Decentralized Periphery) and processes both Selectable Predetermined and Block transfer commands. It supports up to 12 Mbaud transfer rates.

Dynamic Data Exchange (DDE) (-B14)

Allows bi-directional communications with a PC over the serial port using Windows 3.x, Windows 95, Windows NT. The DDE links the HI 2151 series weight controllers to a Windows based application software such as: Wonderware, Visual Basic, Excel, Lotus 1-2-3, or Quattro Pro.

Peak Hold (-C1)

Displays and stores the highest Gross weight value measured until cleared by the front panel Key pad or from a remote command. This option is generally used in testing to determine peak forces a product or material can withstand. It can also be used to track the highest force applied to the scale.

Rate-of-Change (ROC) (-C2)

The ROC option measures and displays the rate at which a material enters or is dispensed from the scale over a period of time. To develop ROC data, a register is used that is 21 entries in length. New weight values are inputted to the register at the rate of 1/20th of the time base. The first register is subtracted from the 21st Register. The 21st register is one time base older than the 1st register. The time frame can be set to units per second, minute or hour. A time base of discrete values is selectable from 1 to 1800.

TTL(Transistor - Transistor Logic) Level Output (-D1)

Provides six TTL level outputs, rated at 500 milliamps per line. A mating connector with eight 24 gauge un-terminated wires, 60 inches long is also provide.

External Setpoint Relays Card (-D2)

This externally mounted card is equipped with six solid state triac relays. Individual relays can be configured as form A or form B by an on board dip switch. Each can be programmed to respond to the standard Net or Gross modes of operation or the optional ROC, Totalizer or peak hold modes. Each have individual setpoint, preact and deadband parameters. A 60 inch interface cable is provided. This option should not be used with the wall mount enclosure.

External Setpoint Relays Card (-D3)

The same as the -D2 option except that the length of the cable provided is six inches. This is designed to mounted in the HI 2151/30WC-WS-D3 wall mount enclosure.

240 VAC 50/60 Hz Input Voltage (-E2)

This is a factory configuration only.

NIST/NTEP Certification Mode Kit (-E3 except for -F4 wall mount)

The HI 21251/30WC is approved for National Institute of Standards and Technology (NIST) applications formally called the National Bureau of Standards (NBS), and certified under the National Type Evaluation Program (NTEP) for up to 10,000 counts when the NIST mode is activated. This option is required when products are to be directly sold based on weight readings of the scale. This kit includes special screws for sealing the instrument, a label plate, a NEMA 4 gasket and a NIST label.

Portable Display and Keypad (-E4)

The HI 2151/30XX-E4 option is used for local set-up, calibration and display of the blind remote version instrument, model HI 2151/30WC-BR.

Intrinsic Barrier Assembly (-F1, -F3 thru -F7)

The Intrinsic Barrier Assembly Option is used only with the wall mount Model HI 2151/30WC-WS. The option provides safety for Class I, II and III, Division I applications.
