IS200STCIH6AED CPU Drive Relay

IS200STCIH6AED is used for positioning control, and the output of the crystal is used to issue pulses. Relays cannot be used to send out pulses, so they cannot be used for positioning control. If you use a relay to control a positioning servo or stepper, you will have to add a positioning module, which is not cost-effective. With a transistor output you can control servos etc. That’s all.

IS200STCIH6AED According to the requirements of the production process, a variety of indicators, inverter / digital DC governor start and stop should be used transistor output, which is adapted to high-frequency action, and a short response time; if the PLC system output frequency of less than 6 times a minute, should be preferred to the relay output, using this method, the output circuit is simple to design, anti-jamming and with load capacity.

IS200STCIH6AED transistor output type principle is the CPU through the optical coupling to make the transistor on and off, in order to control the external DC load, fast response time (about 0.2ms or even less). Transistor outputs are generally used for high-speed outputs, such as servo / stepper, etc., for high-frequency outputs: such as temperature PID control, mainly used in stepper motor control, but also servo control, as well as solenoid valve control (valve action frequency).
