Honeywell HNS50049911-001 Transmitter Display Module

Honeywell HNS50049911-001 Transmitter Display Module

Product Description

HNS50049911-001 is a basic LCD display assembly for the Honeywell SmartLine ST800 series, classified as an internal replaceable maintenance spare part for the transmitter. It is compatible with ST800, STG800, STD800, and STA800 intelligent pressure transmitters (4-20mA + HART protocol). The module integrates a liquid crystal display and operation buttons, enabling on-site reading of process variables, alarm diagnostic information, and local configuration and calibration. The modular structure allows for on-site disassembly, replacement, and assembly. The original factory has discontinued it, and market-available spare parts are used for fault replacement (LCD screen damage, button malfunction, no display faults for repair), but they cannot operate independently. They need to be used in conjunction with the transmitter motherboard, and the hardware version must match. Incompatible versions will cause display abnormalities.

 Product Performance

1. It supports on-site local configuration of the transmitter, enabling zero-point calibration, range setting, and loop testing operations without the need for a handheld controller.
2. It can display measurement values, alarm codes, and equipment diagnostic status, facilitating on-site troubleshooting.
3. The display screen can be rotated at multiple angles, adapting to different installation orientations of the transmitter, making it convenient for reading.
4. It supports square root display, suitable for differential pressure and flow measurement conditions.
5. It is modular and plug-and-play, allowing for direct replacement at the site without the need to modify the wiring of the transmitter itself.
6. It must be compatible with the hardware version of the transmitter’s main control board. Incompatible versions will result in garbled characters and no display.

Application fields: Industrial sites such as petrochemicals, power plants, metallurgy, water treatment, etc.; On-site display and on-site debugging of pressure, differential pressure, and absolute pressure transmitters; Spare parts for factory instrument maintenance and repair, used for replacing faults of the ST800 full series SmartLine pressure transmitters.
