If you have a machine with one or several small AC motors, rated voltage between AC220V, 200W-50W, you need to use the PLC to control its action, do not want to use AC magnetic contactor to occupy the place, do not want to use Relays are easy to break, so what good products can replace them?

PLC thyristor amplifying board can be selected to control AC by DC, non-contact control, advantages take up little space, long service life can reach 89A through current and electricity, meaning, can directly control 500W220V AC motor, AC motor has 2 times start Current, can start and stop with high frequency, generally used in the automatic production line of electric drums, small chainsaws, automatic balers, some small machines used more AC small motor, or some machines can not use the cylinder, use the motor Instead, thyristor amplifying plates, ordinary two-phase small AC motors, and thyristor amplifying plates can be used to achieve high-speed forward/reverse switching. The response is 3 times faster than electromagnetic switches. It can also be used instead of solid state relays to control the heating of heating wires.

PLC amplifying board is a relay board used for isolation and amplifying current between PLC and load, so it is also called IO relay board. Its role is to improve the carrying capacity of the PLC, protect the PLC from overvoltage, overload, load short circuit and other failures, resulting in damage to the PLC host.

PLC amplifier board is to replace the intermediate relay, solid state relays effectively reduce the volume of space occupied, because now PLC has developed for 50 years has been to a small volume, miniaturization of the direction of development, then the PLC's peripheral circuits are also followed by integration, such as the 90s PLC control The circuit has time relays, counters, and switches. Now it's different. Now the man-machine interface can replace numerous switches, timers, and counters. This is the PLC's input circuit. Then the PLC's output circuits are relays, solid state relays and the like. , Also to the direction of integration, replace the relay relay with a relay amplifier board (replacement of the relay module) Advantages Amplifier board with protection circuit, ordinary relay without protection circuit, solid state relays are replaced by transistor amplifier board and can Silicon-controlled amplifier board, transistor amplifier board is to control the DC load, thyristor amplifier board is to control the AC load, these two kinds are used for high switching frequency occasions.
