Project Description

3.5-inch LCD digital readout DRO (WB-55)

using the 3.5-inch real color LCD screen, mechanical keys, and large font display, after a power failure to remember the current position wide voltage input range, input voltage AC 90V-240V, all can work normally. Optional RS232 interface, convenient to communicate with computer or PLC, feedback data. LCD digital readout(DRO) can be installed on a variety of machine tools or equipment, such as lathes, milling machines, grinding machines, boring machines, spark machines, and fine hole discharge machines.

with a grating scale for the machine tool to display measurement positioning.
