Summary
Sun Yuan ISO D-O1 is a newly developed industry smallest volume low power passive PWM pulse width modulation signal isolated conversion to two-wire 4-20mA transmitter IC. The IC works by feeding the back stage (output terminal) current loop, receiving the PWM signal from the front stage equipment, and outputting the corresponding 4-20 mA standard two-wire current signal after isolation and conversion.
SunYuan ISO D-O1 series PWM pulse width transmitter is a hybrid integrated circuit which converts the duty cycle of PWM square wave signal into analog standard signal through isolation. The product is a low cost, small volume standard SIP8 Pin flame retardant IC package, which includes signal coupled high speed isolation converter circuit, precision reference voltage source switch control circuit, low pass filter circuit, drive amplifier circuit, VI conversion circuit and so on. The product has the characteristics of high conversion precision, good linearity and wide supply voltage range (12-36 VDC) of the output circuit. The integrated process structure and new technology isolation measures enable the device to achieve: signal input and output 3000 VDC isolation, and to meet the industrial wide temperature, humidity, vibration of the site harsh working environment requirements.
Sun Yuan ISO D-O1 uses high-speed photoelectric coupling isolation mode and high-efficiency post-feed technology to achieve accurate isolation and conversion of PWM signals to 4-20 mA standard signals. It can match the standard analog input ports (such as PLC, DCS, FCS) of various types of instrumentation equipment. The installation design of two-wire super-small volume (22.0X11.0X9.0mm) standard PCB board without power supply can effectively simplify the selection of user system design scheme, reduce installation volume and wiring cost. The product also has extended DIN35 standard guide rail installation and PIM panel display embedded installation mode. DIN rail mounting mode can realize signal one in and one out, two in and two out, three in and three out and other multi-channel transmission functions. PIM panel embedded intelligent transmitter can realize the intelligent functions of analog signal isolation display, alarm control and long-distance undistorted transmission. Widely used in metallurgical mining, petrochemical, power equipment, medical equipment, industrial automation, new energy facilities and military research and other fields, users can customize appropriate products according to the needs of the scene.
