Design: Pulse signal cycle delay timer switch adopts 16 photoelectrically isolated digital inputs and 3 photoelectrically isolated digital outputs Features: The delay timer switch has upgraded the algorithm, supports soft interpolation, and fixes the arc interpolation error of the old version Working mode: Cyclic delay timer delay can simulate spindle control 0-10V spindle control (can be modified to PWM output) Practical: The interface of the cycle delay timer switch is clear, simple, and powerful, which can almost meet all requirements Safety protection: The cycle delay relay has a button emergency stop function (STOP button), and has reverse connection protection, and the reverse connection will not burn
