CI854A-eA 3BSE030221R2 CPU Drive Relay

CI854A-eA 3BSE030221R2 is used for positioning control, and it is necessary to use the output of the crystal 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.

CI854A-eA 3BSE030221R2 according to the requirements of the production process, a variety of indicators, inverter / digital DC governor start stop should be used transistor output, which is adapted to high-frequency action, and a short response time; if the output frequency of the PLC system for less than 6 times a minute, should be the first choice of the relay output, using this method, the output circuit is simple to design, anti-jamming and with a strong load capacity. Relay output should be preferred if the output frequency of PLC system is less than 6 times per minute.

CI854A-eA 3BSE030221R2 transistor output type is based on the principle that the CPU makes the transistor turn on and off through optical coupling to control the external DC load, with 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).
