YH-905 Signal Generator Version Portable Hart Modem Support Remote Debugging with Mobile APP Replacement for Trex 475 USB Modem

YH-905 Signal Generator Version Portable Hart Modem Support Remote Debugging with Mobile APP Replacement for Trex 475 USB Modem

Description:
- YH-905 is a HART modem, which can communicate with any manufacturer's HART instruments for Rosemount, for ABB, for E+H, for Siemens, for KROHNE, for Yokogawa, etc. It can be used as a HART manual operator in conjunction with the mobile app provided by our company.
- The mobile app is free to download and use.
- YH-905 has high integration, small size, and is easy to install and carry; The PC and mobile versions use a standard USB interface and are powered by a USB bus. In addition to supporting USB connection, the Bluetooth version also has a built-in lithium battery, which can wirelessly connect to mobile phones/Pads without the need for additional power supply. Both versions offer a built-in 24V power supply and/or 250 ohm resistor that can be controlled by a toggle switch, and can be debugged even when the on-site instrument is not yet powered.
- Choose for Android app version or download the "HART Modem" from the App Store for iPhone/iPad (for iPhone/iPad only support Bluetooth and Signal Generator versions) to support remote debugging. Data can be transmitted remotely through the internet, enabling remote device debugging.

Features:
- Full platform operation, supporting for Windows, for Android, and for iOS systems simultaneously.
- Tested through the official FSK Physical Layer Test Kit of the HART Foundation.
- High integration, mini size, with a host size only 72 x 52 x 20mm (L x W x H).
- Built-in 24V power supply, convenient for debugging on-site instruments when not powered on.
- Built in 0-22mA current signal generator, which can directly drive the valve positioner.
- The Bluetooth version has a built-in lithium battery, which is wirelessly connected to the phone/Pad without the need for additional power supply.
- The Bluetooth version is designed with ultra-low power consumption and large capacity, and is equipped with a built-in lithium battery for ultra long battery life. When the 24 power is turned off, the built-in lithium battery can work continuously for 100 hours. Even if the 24V power is turned on to power the instrument, it can still work continuously for 30 hours at 4mA output, and can work continuously for 10 hours at 20mA output.
- The APP version supports remote debugging, which can be done through the internet. (Using two mobile phones or Pads, one of which is connected to the instrument through YH-905, and the other can be remotely connected to the instrument through the internet)
