14.Analog signal to PWM programmable isolation transmitter IC: ISO U(A)-P-D-Q
SunYuan ISO U(A)-P-D-Q series products are industry-leading technology, small size (SIP12 Pin), low-cost programmable control isolation transmitter newly developed by Sunyuan.The analog signals output by sensors, instruments, and transmitters can be isolated and amplified, AD converted into PWM square wave signals, and pulse frequency control and programmable output can be realized.Sensors,transmitters,instruments and control equipment can be embedded with PC and PLC/DCS to form an Ethernet/Internet of Things, RS232 bus network and communicate with the network immediately after the IC is embedded to upgrade the traditional control equipment on site to industrial control intelligent equipment , It is convenient for users to remotely monitor.
SunYuan ISO U(A)-P-D-Q integrates multiple high isolation DC/DC power supplies,analog amplification and conversion circuits, programmable MCUs, signal isolation control circuits, etc. in the same module, which is especially suitable for AD isolation and transformation of analog signals in industrial sites Send, fieldbus, Ethernet Internet of Things, PLC/DCS host computer collects and analyzes the signals of multiple sensors.The internally integrated high efficiency DC-DC isolation power supply separately supplies power to the internal input conditioning circuit, micro single-chip AD conversion circuit and output signal isolation circuit. SMD process structure and new technology isolation measures enable the device to achieve: 2500VAC three isolations between auxiliary power supply and analog signal input and PWM signal output, and the input signal and the communication serial port share the same ground.And it can meet the requirements of industrial-grade harsh working environment with wide temperature, humidity and vibration.
SunYuan ISO U(A)-P-D-Q series products are very convenient to use, and can realize the isolated transmission function of analog signal and PWM signal without any external components.The 12-pin single in-line ultra-small size (33.0X15.5X10.5mm) and standard PCB board mounting design effectively simplify the user's system design options and reduce the volume and wiring costs.Products include IC package mounted on PCB board, DIN35 standard rail mounting and PIM panel display embedded mounting mode. The DIN rail type installation method can realize the signal input and output isolation transmission function.The PIM panel embedded intelligent transmission meter can realize various functions such as sensor analog signal isolation display, alarm control and long-distance distortion-free transmission.It is widely used in the fields of metallurgy and mining, petrochemical industry, power equipment, medical equipment, industrial automation, new energy facilities and military scientific research. Users can choose suitable products according to site needs.
