Process load cell signals to give analog or digital outputs with high accuracy.
A range of accessories eases the assembly of low cost weighing systems.
DJB500 is a low cost 4 input channel device that sums the 4 inputs and provides scaled, filtered output to both an RS232 port and an RS485 multi-drop bus. Up to 32 DJBs can be connected to the RS485 multi-drop bus. Its wide command set includes full setup and calibration plus ability to read individual channels in raw data, mV/V scaled values or fully scaled, filtered 4-channel combined output. The advanced filter allows superior vibration damping while still giving fast response.
All weighing functions necessary for operation of weighing system such as Zero, Tare, motion detection, Units and error monitoring are performed by the DJB500. The calibration of each corner and of the scale is handled by the DJB500 through a calibration sequence initiated via the RS232 serial interface. Calibration constants are stored in EEPROM on board. Calibration security is effected by software which requires a special password to be entered. The weight data rate is setup selectable to cater for high accuracy static weighing (10 conversions/sec) or medium accuracy dynamic weighing (80 conversions/sec) applications.
Compact, complete and convenient to use.
All setting is made through the serial interface.
VT100, VT120 protocol.
Simple calibration, Test and Setting via HyperTerminal program.
Automatic units conversion, zero tracking.
IP65 / NEMA-4 outdoor rated enclosure.
The 1410 is an analog transmitter that connects to the analog inputs of PLCs and computer data acquisition systems. It operates from the 24 volt DC power provided by most PLCs, or from the companion 1040 power supply and provides excitation for 4 load cells or pressure transducers. Output is selectable, 4-20mA, 0-5 or 0-10 volts. Used in our BatchTron and many other O.E.M. products, the 1410 sets the standard for accuracy.
Input range: 0.15 - 4 mV/V full scale.
Accuracy at room temperature: ± 0.01% of full scale (1 part in 5000).
Temperature stability: ± 0.001% per ° C at 0.5 mV/V full scale or greater (± 0.05uV/.° C)
Output: 4-20mA 0-20mA, 0-10V or 0-10V full scale.
Power: 15-30V DC at 145 mA max when powering four 350 ohm load cells.
Physical: board size 87.5 x 70mm (3.45" x 2.83").

For "summing" (combining) the outputs of up to four load cells, the 1280 is one of the smallest and lowest cost units around. But that doesn't mean that it isn't accurate. The 1280's signal trim circuitry and integrated high-stability summing network mean that it is also the most stable and accurate on the market. Three adjustments are for side to side, side to side and end to end, making it ideal for platforms and hoppers. Thousands are in use in commercial platform scales. Do not use the 1280 for four section truck scales; use the 2450 or Mod Box Plus for this purpose.
1280 gives 3% total adjustment, is 4" x 2.75" in size and is physically compatible with the 1410 transmitter family.
1080 LOAD CELL SWITCHING RELAY
If you've ever tried to switch load cell signals with a conventional relay, you know that it can't be done; the heating caused by operation of the relay produces thermal voltages which create drift like you've never seen before! The solution is a special relay which is thermally balanced. The 1080 operates from selectable voltages of 12, 24 or 110 volts AC/DC and provides 2 pole single throw switching. Each scale or load cell circuit requires one 1080 for switching.
2420 SPAN/ZERO ADJUSTMENT MODULE
The companion for the 1080 switch above, or the 1160 solid state module from the 1100 family, the 2420 provides span and zero trimming for two separate scales or load cell circuits with the same nominal capacity and dead load. The combination 1080/2420 allows two (or more) scales to be automatically selected by a single indicator or other data acquisition device with only one set of calibration adjustments.
