General Details

OLT Overload controller

OLT Overload control indicator provides integrity with other elements in the panel with its box suitable for rail mounting, while providing easy connection to industrial control devices. It is a robust and quality control unit designed for use in cranes with 4 relay outputs. It can communicate with computer and external display via RS 232 serial port, 110-220 volts operating voltage. High precision 24 bit sigma delta ADC can connect 4 loadcells (350Ω), calibration without reference weight (mV / V). Housing suitable for DIN rail mounting.

Application

-Crane overload control

-Elevator overload control

-Industrial weighing applications

-Industrial weighing
