DIN4 DIN-Rail Analog Signal Isolator with Wide-Range Supply

The SunYuan DIN4 Series Wide-Range Power Supply DIN-Rail-Mounted Analog Signal Isolation Amplifiers feature a wide-range single power supply of 5–36 VDC and offer three optional isolation technologies: optoelectronic, magnetic, and capacitive isolation. They provide 2500 Vrms of full electrical isolation between the power supply, input, output, and channels. The DIN4 Series supports the isolation, amplification, and conversion of various analog voltage and current signals, including millivolt signals, bipolar voltages, and 4–20 mA signals. Each unit is calibrated before shipment, achieving accuracy classes of 0.1 and 0.2, with nonlinearity as low as ±0.01% FSR. Designed for standard 35 mm DIN-rail mounting, these compact modules are ideal for space-constrained control cabinets and operate reliably across an industrial temperature range of −40°C to +85°C. They effectively eliminate ground-loop interference in industrial environments and help address signal attenuation, noise, and drift during long-distance analog signal transmission. Built-in protection circuits against overvoltage, overcurrent, and reverse polarity are provided at the power supply input, signal input, and signal output, allowing convenient on-site wiring and installation. The series supports multiple configurations to meet different application requirements, including DIN4 1X1 (one input, one output), DIN4 1X2 (one input, two outputs), and DIN4 2X2 (two inputs, two outputs). These models provide single-channel and multichannel analog signal isolation, amplification, and conversion between instruments, sensors, and controllers. The DIN4 Series is widely used in railway voltage monitoring, generator and motor safety monitoring, remote monitoring of power transmission and distribution systems, signal interfacing between instruments and sensors, safety isolation barriers for medical equipment, industrial robot automation, chemical processing, nuclear power equipment, and other industrial applications.
