CP-9200SHSVA YASKAWA output relay

Description

Technical Specifications CP-9200SHSVA

The output of relay is generally strong current controlled by weak current. That’s what circuit control says.
In many automation equipment, the circuit ultimately needs to control some executive parts (such as motor, electromagnet). The circuit control of these executive parts can be carried out by relays, bidirectional thyristors, transistors and other switching devices. Therefore, for the output end of the circuit, there are corresponding “relay output, bidirectional thyristor output, transistor output” and other types.
In fact, an ordinary relay is equivalent to a single-pole double-throw switch, which controls the external circuit with three pins. When the control current is blocked (default state), the middle pin is connected to a left pin, and when the control current is connected to the right pin. The suction of the relay requires current to act on the electromagnet. Therefore, it is not enough to rely on the I/O port of the single chip microcomputer to make the relay draw, so a drive should be added (to play the role of power amplification and provide enough current for the relay), then the single chip microcomputer uses the I/0 port to control the drive, and then the drive circuit (driver chip such as UM2003) outputs enough current to make the relay draw, that is.
The output of relay, relay housing above write the output current voltage, that is, use weak current to control strong electricity, strong electricity to what extent, is the output parameters (such as 220V,2A), the transistor output and relay output are different, although both are control devices, but the transistor input and output no electrical isolation, and the relay is electrically isolated, When the volume is limited, the response time is very short, are often controlled by transistors, and when the voltage is relatively high, the current is relatively large, to pay attention to personal safety, often use relay, as for the relay as the MCU input, it is not necessary, relay is an isolation switch, weak current control strong current, it does not seem to receive the input pin, Unless you use an external signal to control the relay, the relay suction state is input to the MCU, that is not necessary, the relay is just a switch with electrical isolation.
