DC 24 Volt 6 Ways Programmable Relay Module With Relay Base Easy Replace

DC 24 Volt 6 Ways Programmable Relay Module With Relay Base , Easy To Replace

There are many low-cost PLC amplification boards with no optocoupler, no heat sink, no protection, they are not very reliable, and their service life is not much better than traditional relays. Really good PLC amplification boards need to be lighted. Coupled isolation.

Why do we need to add optocoupler isolation, to explain below, PLC transistor output control PLC amplifier board, if the PLC amplifier board is not optocoupler isolated, the load will have a strong power string will directly damage the PLC amplifier board, strong electricity through the amplifier board and then string to the PLC The output terminal damages the PLC, causing losses. If an optocoupler is added, the input and output of the optocoupler are not directly controlled. The output is amplified by an optical signal, and the load is short-circuited or has a strong incoming power. PLC amplifier board, will not damage the PLC, because the PLC and the load is isolated with light, plus optocoupler PLC amplification board, not only has the amplification of the PLC output current amplification, but also the role of isolation anti-jamming, if Your machine has high frequency, super-wave interference signal is large, photoelectric switch, proximity switch, these signals to access PLC, high-frequency signals will interfere with the PLC, so that the PLC can not work, add the PLC isolation amplifier board on it PLC amplification board is really one of the indispensable components in industrial automation. In the future, PLC amplification board will change all aspects of industrial control.

PLC amplification board, also known as PLC output amplifier board or PLC isolation amplifier board, is an isolation amplifier circuit between the PLC output and the load, can also be said to be a conversion circuit, generally isolated with optocoupler, PLC amplifier board was first developed is It is used in injection molding machines and blow molding machines, die casting machines, and later hydraulic presses, automated production lines, punch automation, thermal power lines, military factories, ships, aircraft carriers are used, robots, robots, communications equipment, oil fields, stage lighting Music fountains, etc., replace the traditional intermediate relays.

PLC amplifier board is also the PLC current amplification, voltage conversion, will be connected to the PLC will be connected to the PLC amplifier board, the same principle, PLC amplifier board is quite intermediate relay.
