Project Description

LED Digital readout(DRO)(WB-6800)

Using 24-bit dedicated counting integrated circuit, counting speed up to 5m/s, remember the current position after a power failure, wide voltage input range, input voltage AC 90V-240V, all can work properly. Optional RS232 interface for easy communication with computer or PLC and data feedback. The digital readout(DRO) can be installed on a variety of machine tools or equipment, such as lathes, milling machines, grinding machines, planing machines, etc., with a grating scale to display the measurement positioning for the machine. The power supply anti-interference ability and signal anti-interference ability reach more than 2200V, baud rate 9600 wide voltage input range AC 90V-240V, both can operate normally.
