Transisitor PLC 4 Channel Amplified Board JR-4J Large Load And Excellent Stability

Transisitor PLC 4 Channel Amplified Board JR-4J Large Load And Excellent Stability

PLC's transistor output channel current is limited by the circuit board wiring, device heat dissipation and power supply system, the rated output current is generally between 0.2 ~ 0.75A, and many field power devices often require large currents to drive the movement of mechanical components, which causes the PLC Insufficient output power. The traditional solution is to install an intermediate relay at the output of the PLC. The PLC output drives the relay coil. High current is provided through the relay contacts. However, the principle of the relay determines that each on-off will affect its mechanical life. At the same time, the greater the current through the contact, the more serious the oxidation of the contact surface, especially in the case of inductive load, relay contact will be caused by the passage of time Point adhesion, the emergence of the amplifier board to solve this problem, the PLC output signal drives the amplifier circuit, high current signal to the device power supply.

When high-power DC equipment such as DC motors, solenoid valves, etc., need to be frequently started, the use of the amplifier board has the unparalleled advantages of conventional relays.
Mainly in:

◆ maintenance-free, no-on-life life limit;
