DC Output Board PLC Relay Module , 4 Channel Weidmuller Relay Board DPDT

Input and output of PLC

Input interface:
The optocoupler consists of two light emitting diodes and a phototransistor.
Light-emitting diodes: In the optocoupler input signal changes, the light-emitting diodes and the input signal to produce the same change in the light signal.
Photo-electric three-level tube: It is turned on under the irradiation of light signal, and the degree of conduction is related to the strength of the light signal. In the linear operating region of the optocoupler, the output signal has a linear relationship with the input signal.
Input interface circuit working process: When the switch is closed, the diode emits light, and then the triode is turned on under light irradiation, and the signal is input to the internal circuit. When the switch is off, the diode does not emit light and the transistor does not conduct. Input signal to internal circuit. It is through the input interface circuit to convert the external switch signal into a digital signal that can be accepted within the PLC.
Output Interface
PLC relay output interface circuit
Work process: When the internal circuit outputs a digital signal 1, there is current flowing through, the relay coil has current, and then the normally open contact is closed to provide current and voltage for load conduction. When the internal circuit outputs a digital signal 0, no current flows, the relay coil has no current, and then the normally open contact opens, disconnecting the load's current or voltage. That is, the internal digital circuit is converted into a signal through the output interface circuit to make the load act or not.
Three types:
Relay output: contact, short life, low frequency, AC and DC load
Transistor output: no contact, long life, DC load
Thyristor output: no contact, long life, AC load
