1、 Product introduction

The differential to TTL module converts the a +, a -, B +, B -... Differential signals output by the servo encoder grating ruler into standard PLC a and B phase high-speed counting signals. The front and rear stage optocouplers are isolated, and the signal is used for closed-loop control, and the accuracy is greatly improved. This product can be used to solve the conversion interface between rotary encoder, grating ruler differential mode output and single chip microcomputer, PLC controller, applied to Siemens, abb, AB, Omron, Mitsubishi, Panasonic, Delta and other PLC high-speed counting module, pulse input terminal, motor encoder, conversion interface between optical grating ruler and PLC controller, inverter signal and PLC The signal transmission between controllers is especially suitable for motor automatic control applications.
