SIGMATEK TAE151 Replacement and Troubleshooting

SIGMATEK TAE151 Touch Display Unit Replacement and Troubleshooting Guide

In the field of industrial automation, updating and upgrading human-machine interfaces (HMI) and display terminals are common tasks for equipment maintenance and upgrading. When the original display unit is discontinued, damaged, or unable to meet new visualization requirements, it is crucial to choose a compatible, easy to install, and reliable replacement product. SIGMATEK TAE 151, as a 15 inch touch display unit, is an ideal choice for replacing old display terminals due to its flexible interface configuration, wide voltage supply, and design that adapts to harsh industrial environments. This article will delve into the replacement selection, installation and debugging, troubleshooting, and maintenance points of TAE 151, providing engineers with a practical technical guide.

Overview of TAE 151 Technical Features

TAE 151 is a 15 inch TFT color display unit with a resolution of 1024 x 768, a color depth of 18 bits (262144 colors), a typical brightness of 350 cd/m ², and a contrast ratio of 700:1. The touch screen adopts an analog resistive thin-film glass touch panel with a resolution of 12 bit controller (USB interface) and supports automatic display detection (IPC support required). Its core interfaces include: 3 USB V1.1 Type-A ports on the front panel, 1 USB Type-A V1.1 port on the back panel, 1 CAN port (2 connections), and S-DVI port. The power supply voltage is+18 to+30V DC, with a typical current consumption of 825mA (at 24V). The power is provided by IPC through S-DVI cable, without the need for additional power supply. In terms of environmental adaptability, the working temperature is 0 to+50 ° C, the storage temperature is -20 to+60 ° C, the humidity is 20-95% without condensation, the impact resistance is 150m/s ², and it meets the EN 61000-6-2 industrial EMC standard. Protection level: Front panel IP54, rear panel IP20 (IP43 with cable tray), NEMA 250 Type 12. The shell is made of ASA plastic and weighs approximately 4.2kg.

Replacement selection and compatibility evaluation

When deciding to replace the existing display unit with TAE 151, engineers need to evaluate the following aspects:

Mechanical dimensions and installation method: The external dimensions of TAE 151 are 358mm x 313mm x 62mm, and the installation hole positions are designed to support switchgear installation and cantilever installation. The installation of switchgear requires selecting installation kits based on the thickness of the board: for board thicknesses of 1.0-3.0mm, use 12-209-021 (screw length 10mm), and for board thicknesses of 4.0-6.0mm, use 12-209-022 (screw length 16mm). For cantilever installation, use 12-209-011 (plate thickness 1.0-3.0mm) or 12-209-012 (plate thickness 4.0-6.0mm). It is necessary to ensure the use of screws of the correct length to avoid damaging internal components.

Interface matching: Before replacing, it is necessary to confirm whether the original IPC or controller supports S-DVI output. The S-DVI cable provides+24V power and video signal, with a length range of 0.3m to 15m. If the original system uses other video interfaces (such as VGA, DVI), the IPC needs to be converted or replaced. The CAN bus interface is used to connect keyboards or other peripherals, and the original system CAN network parameters need to be confirmed.

Power requirements: TAE 151 is powered by S-DVI with a voltage range of+18-30V DC, ensuring that IPC can provide sufficient power (typical 825mA). If using an independent power supply, it must comply with UL current limiting requirements (0-20V DC maximum 5A, or 20-60V DC maximum 100W), and the current limiting components must be NRTL certified.

Environmental adaptability: Confirm that the working temperature is within the range of 0-50 ° C and the humidity does not condense. If installed in areas with chemical corrosion risks, reference should be made to the chemical tolerance table. ASA shells are stable to most acid, alkali, and salt solutions, but toluene, acetone, ether, and ethyl acetate can have an impact.

Mechanical installation and grounding

When installing TAE 151, first insert a sponge rubber strip (diameter 3mm) into the groove on the back of the terminal to ensure sealing. Then fix according to the installation method:

Installation of switchgear: Insert the terminals into the openings of the switchgear and secure them from the back using matching screws. Note that the length of the screw must match the thickness of the board.

Cantilever installation: Use a cantilever installation kit to secure the terminals to the cantilever.

After installation, the display unit must be connected to the grounding bus through the flat connection terminal on the back to ensure fault free operation. Good grounding is the key to suppressing electromagnetic interference and ensuring safety.

Electrical connection and configuration

S-DVI connection: Use a dedicated S-DVI cable (26 pin HDSubD) to connect IPC and TAE 151. This cable simultaneously transmits video signals and+24V power supply. It is strictly prohibited to plug and unplug S-DVI cables with power on, otherwise the interface may be damaged. The cable length is selected based on the actual distance, with a maximum length of 15 meters.
