12.Small volume PWM pulse width signal conversion high precision isolation transmitter IC: ISOS D-P-U
SunYuan ISOS D-P-U series products are the industry leading technology, small size (SIP7 Pin) and low cost PWM pulse width modulation signal isolation transmitter IC newly developed by Sunyuan.It can isolate and convert the duty cycle of the PWM square wave signal output from the inverter, single-chip microcomputer, PLC/DCS, and instrumentation into analog signals such as standard 0-5V/0-10V to realize the isolation and amplification of the DA conversion of the single-chip PWM signal and transmission control function.
SunYuan ISOS D-P-U series products are particularly suitable for DA conversion and isolation transmission of PWM pulse width modulation signals in industrial fields, single-chip microcomputer, field bus, Ethernet Internet of Things, PLC/DCS upper computer to multi-channel sensor signal acquisition analysis and control.The internal SMD process structure and new technology isolation measures enable the device to achieve:the PWM signal input and analog signal output 3000VDC isolation.And it can meet the requirements of industrial-grade harsh working environment with wide temperature, humidity and vibration.Due to the volume limitation, the internal power supply of the product is not boosted and isolated, so the power supply voltage value for the product must be higher than the signal output voltage value by more than 3VDC.(For example: the output signal is 0-5V, the power supply voltage needs to be above 8VDC, 9VDC or 12VDC power supply can be selected)
