HD5500Series isolated safety barrier input/output/power three port isolation, meeting the requirements of [ExiaGa] Ⅱ C explosion-proof level, suitable for the most dangerous zone 0 and the most dangerous medium.
HD5500Adopting advanced low-power circuit design, power consumption is reduced by 40% compared to the previous generation product; And adopting the design of convective heat dissipation holes between terminals, it brings a more complete hot runner and more sufficient heat dissipation. It is matched with the same 12.5mm thickness as other similar products, making high-density installation possible and saving more than 30% of cabinet space.
HD5500Adopting an integrated USB communication cable eliminates the need for serial port transfer, making configuration easy and facilitating communication with the host computer.
HD5500Bottom power supply rails can also be used for power supply, effectively reducing the workload of power wiring. Save labor costs, facilitate rapid installation and system expansion.

1. Choose HD5573 or HD5575, please indicate the input signal type and range. For thermocouple input signals, the wiring terminal position labeled 3/4 on the product will be equipped with HD55-CJC terminals (containing cold end compensation components and cannot be used for cable connections); For other input signals, the terminal positions labeled 3/4 on the product will be equipped with regular terminal blocks, which can be used for normal cable connections.
2. Our company provides Inscan HDC communication kit (including upper computer configuration software and matching dedicated communication cables) and HD55-CJC terminals or ordinary wiring terminals as options. With this communication kit, users can set the signal type and range of the HD5573 and HD5575 temperature transmission isolation safety barriers through a PC. When the signal type changes between thermocouple and thermistor, it is necessary to correctly match the HD55-CJC terminal or ordinary wiring terminal to ensure the normal use of the product.
3. The default input signal for HD5526 is a switch value. When selecting 24V active input, it should be noted in the selection process.
