INTRODUCTION
The DAT 500 is a transmitter of weight to be combined with the load cells to detect the weight in every
situation.
The display allows easy reading of the weight, the status of the instrument, the setting parameters and
errors.
The 4 keys located below the display allow the operator to perform the functions of ZERO, TARE,
GROSS/NET switching, setting of the setpoints weight, setting and tare both theoretical than real.
The DAT 500 uses the serial port RS232 with ASCII and Modbus RTU protocols for connecting to a PC,
PLC and remote units. In parallel with the RS232, a USB port available.
They are always available 2 programmable weight setpoints and the control of the maximum weight
value reached (peak).
The RS422/RS485 serial output allows you to connect up to 32 addressable devices.
The availability of the most common fieldbuses, as an alternative to the RS422/RS485 port, also allows
the transmitter to interface with any supervision device currently offered by the market.
Available versions:
• DAT 500:
weight transmitter with serial output RS232, RS422/RS485 and Peak function. Suppor-
ted protocols are Modbus RTU, continuous, slave and the ones upon request. Two programmable
setpoints, 2 inputs and Peak function.
• DAT 500/A: version with the analog output.
• DAT 500/PROFIBUS: weight transmitter with serial output RS232 and PROFIBUS DP.
• DAT 500/DEVICENET: weight transmitter with serial output RS232 and DEVICENET.
