DC24V PLC SCR Module , Output Amplified Module PLC PNP NPN Control Board

The solid state relay is actually a PLC amplifying board. The internal principle is exactly the same. The AC solid state relay is a photocouple-driven two-way thyristor to convert voltage and current. The advantage of the solid state relay is that there is no mechanical contact and it is a semiconductor. On-off, the reaction speed is more than 5 times mechanical contact relay, the only is the volume is too large, the installation is not convenient, but also additional heat sink.

The thyristor amplifying board can directly replace the AC solid state relay, which is the same as the principle of the solid state relay. Compared with the solid state relay, the advantages of the two-band heat dissipation, easy installation, rail mounting, no drilling so porous, a SCR Magnification board can do 20 ways from 2 way, the installation is very convenient, the bad can still be repaired, the solid state relay is a one-time, the bad can't be repaired, increase the cost greatly, another advantage saves space, it is the solid state relay One-third position takes up space. Maintenance is more convenient to have output indicator, can watch the board is not normal operation, thyristor amplifying board can directly control the heating, electromagnet, lamp, hydraulic station, AC motor, electric drill and other loads.

Thyristor amplifier board, also known as thyristor amplifier board, is the same as a guillotine knife. It controls the on and off of the electricity and controls the AC power. Therefore, it is also known as the PLC AC amplifier board because it has no mechanical contacts, also known as solid state relays. Magnifying board

Thyristor output circuit

Bidirectional thyristor output circuit can only drive AC load, the response speed is faster than the relay output circuit, and the service life is longer.

The drive capability of the triac output is smaller than that of the relay output. The allowable load voltage is generally AC85 to 242V; the single-point output current is 0.2A to 0.5A. When multiple points share the common terminal, the output current at each point should be reduced. (If the triac output has a 0.3A single-point drive capability, the maximum allowable output is 0.8A/4 at 4 points common.)

In order to protect the thyristor, RC resistance absorption element (usually about 0.015uF/22Ω) and varistor are usually connected at both ends of the thyristor of the PLC internal circuit. Therefore, when the thyristor is turned off, the output of the PLC still has 1 to 2mA. Open-circuit leakage currents, which may cause some small relays to fail when the PLC output is OFF.
