The LW Series Signal Isolator is an electrical connection between the industrial field instrument and the control room. It effectively solves the interference problem of the industrial automation control system through the reliable isolation between the input-output and the power supply to ensure the stable and reliable operation of the system. This series of products adopts the international leading PCB transformer isolation technology, combined with advanced and efficient digital circuits, to further improve the anti-interference of the detection and control loops based on greatly improving the isolation strength of the products. At the same time, the current, voltage, resistance, galvanic couple, frequency and other signals are converted and distributed to meet the requirements of industrial automation control systems to a greater extent.

The LW series isolation barrier transmits the current signal, thermal resistance, thermocouple signal and switching signal from the hazardous area to the safety zone from the hazardous area to achieve complete isolation between the input-output-power channels. The products are designed according to the national standard GB3836.1 2010 "Explosive environment Part 1: General requirements for equipment", GB3836.4 2010 "Explosive environment Part 4: Equipment protected by intrinsically safe "i"". The barrier is an intrinsically safe associated device that connects the industrial field instrument to the control room meter. In addition, it can convert and distribute signals such as current, voltage, resistance, and galvanic to meet the needs of various industrial automation control systems.

1, 12.5mm ultra-thin, load capacity 350Ω (factory default, can specify the load) perfectly fits various PLC / DCS. Isolation, power distribution can be universal, high precision ± 0.1% F.S., low temperature drift, automatic zero calibration.
2, the use of new PCB transformer technology, input terminal current limit, protection of field equipment safety, super anti-interference ability. The input-output-power terminals have a withstand voltage of up to 2500VAC.
   The thermal resistance and thermocouple input parameters are directly programmed by the USB adapter, and the input parameters are read. No external power supply is required, and the parameter range can be adjusted according to the needs of the site.
 
3, humanized shell design, the bottom design of the heat dissipation channel; the terminal uses 0.5 ~ 2.5 (mm2) cable, the slotted cylinder head M3 screw is tightened, the screw torque is below 0.8Nm, the wiring is fast and the terminal can be plugged in and out. Front-end power indicator, feedback status of the instrument at any time.
4. It adopts 35mm standard DIN rail card type installation, low power consumption, small heat generation of the instrument, and can be installed intensively.
Signal isolators, safety barriers and other products are designed and manufactured in strict accordance with the latest regulations of GB3836.1-2010 and GB3836.4-2010 and passed the EU CE certification, national intrinsic safety explosion certification and ISO9001 quality management system certification. The company strictly implements the quality management system, and the products adopt standardized import production lines and high-precision testing equipment for standardized production to ensure the reliability of product quality.
