Description
UNS0881B-PV2 3BHE050077R0102 is a digital logic controller mainly used for automatic control. PLC by the internal CPU, instruction and data memory, input and output units, power modules, digital analog and other units of the modular combination, can receive (input) and send (output) a variety of types of electrical or electronic signals, and use these signals to control or supervise almost all kinds of mechanical and electrical systems. The features of UNS0881B-PV2 3BHE050077R0102 include strong versatility, easy use, wide adaptability, high reliability, strong anti-interference ability, simple programming and so on. One of its biggest advantages is that the input/output function modules are complete, which can provide corresponding templates for different field signals (such as DC or AC, switching quantity, digital quantity or analog quantity, voltage or current, etc.), and directly connect with industrial field devices (such as buttons, switches, sensing current transmitters, motor starters or control valves, etc.). It is connected to the CPU motherboard through the bus. The digital input module is an electronic device used to connect external mechanical contacts and electronic digital sensors, which is part of the PLC (Programmable logic controller) control system. The main function of this module is to convert the external digital signal from the field into the PLC internal signal level, and transmit it to the CPU for program processing. Digital input modules usually have input channels, which are used to receive external switching quantities or digital signals, such as switching on and off, button pressing, sensor signals, etc. The input circuit is generally equipped with a RC filter circuit to prevent the wrong input signal caused by the input contact jitter or external interference pulse.
