Isolation Amplifier 506039868 Qq Description:

SIP12 Pin package current loop isolation chip: ISO 4-20mA, is a single-chip two-wire isolation interface IC chip, used for industrial field analog signal isolation and suppression of each channel between the sensor and PLC, DCS, inverter 4-20mA current loop isolation acquisition distribution. The IC contains modulation and demodulation circuits, coupled isolation conversion circuits, and the like. The small input equivalent resistance allows the IC input voltage to reach an ultra-wide range (8.5 to 28 VDC). The user can achieve long-distance, distortion-free transmission without an external power supply. The internal ceramic substrate, printed resistor process and new technology isolation measures enable the device to reach 3KVDC insulation voltage and meet the harsh environment requirements of wide temperature, humidity, vibration and other industrial environments.

Isolation amplifier transmitters are generally used in industrial environments where the power environment is complex. To prevent the on-site environment from causing various kinds of interference or damage to the products, based on many years of production experience and user feedback for different environments, the performance of the products is not Under the premise of influence, we will gradually improve and improve product protection measures. For DIN 35 rail mounted products, these protection circuits are placed in the product according to the site, and the user can use it directly. For IC packaged products, they cannot be loaded into the protection circuit due to the limited size space. Therefore, the user is required to use the environment to install protection circuits for signal input, output, and auxiliary power of the IC package product. Shunyuan Science and Technology provides you with several basic protection circuit reference programs: IC package isolation amplifier transmitter external protection circuit Download

Industrial field sensors and instrumentation, PLC, DCS and other control systems often cannot work properly due to system interference, active signals, passive signals, active loads, passive load signal conflicts, and impedance matching issues. The correct choice of isolated amplifier transmitter can effectively solve the problem of signal interference, impedance matching and conflict between the signal source and the control system. The ISO series isolation amplifier transmitter products developed and produced by ShunYuan Technology can meet the analog signals collected by various sensors such as instrumentation, PLC, DCS, DSP equipment and on-site temperature, displacement, pressure, frequency, etc., through isolation, amplification and conversion.
