Description
- Key Technical Specifications
Parameter Details Electrical Parameters Works with 24VDC voltage, and the voltage range can reach 18VDC – 32VDC; each channel has a 50mA fuse, and the maximum current of the field power supply per channel is 10mA; the field power supply consumption is about 0.25W. Physical Indicators Different sources have slightly different data. One set shows the size is 111mm×335mm×51mm and the weight is 0.9kg; another set shows the size is 16cm×16cm×12cm and the weight is 0.5 – 0.8kg. It is compatible with standard DIN rails for easy installation. Environmental Adaptability The operating temperature is mostly 0°C – 60°C; the non-operating temperature can reach -25°C – 70°C. It can work normally in an environment with 10% – 95% non-condensing humidity. Some versions have an IP65-rated cast aluminum shell, which is dustproof, moisture-proof and corrosion-resistant. Safety & Compliance Adopts triple modular redundancy (TMR) design, with an MTBF of more than 100,000 hours. It has passed certifications such as CE and UL, and meets the safety operation requirements of critical industrial environments.

- Field Application & Problem Solved
In industries such as oil refining and chemical engineering, a large number of sensors and other field devices need to transmit digital signals to the central control system, and signal loss or interference during transmission may lead to misjudgment of the system and cause safety accidents. The T8800 can well solve such problems. For example, in a petrochemical plant’s pipeline pressure monitoring system, multiple pressure sensors generate digital signals. The T8800 can connect 40 sensors at the same time, and the fuse of each channel can avoid the overall failure caused by a single channel fault. Its signal conditioning function also filters out the electromagnetic interference from the surrounding equipment, ensuring that the input module accurately receives the pressure data. When the input module needs to be maintained, its hot replacement function can avoid system downtime, ensuring continuous operation of the pipeline monitoring work.

- Installation & Maintenance Pitfalls (Expert Tips)
- Improper Fuse Replacement: Each channel of the module is equipped with a dedicated 50mA fuse. If a fuse with a larger current is used for replacement during maintenance to save trouble, it may damage the channel circuit when the current is abnormal. It is necessary to use fuses of the same specification.
- Neglecting LED Indicator Check: The on-board LED can indicate the integrity of the field power supply. If the indicator status is not checked during installation, the problem of poor power supply connection may not be found in time, resulting in signal transmission failure. It is necessary to confirm that the LED indicator is normal after installation.
- Incorrect Rail Installation: Although it is compatible with standard DIN rails, if the module is not clamped tightly during installation, it may loosen due to industrial site vibration, leading to poor contact. It should be fixed firmly according to the installation specifications.
- Ignoring Voltage Range: The module’s voltage range is 18VDC – 32VDC. If the connected power supply voltage fluctuates beyond this range and no voltage stabilization measures are taken, the internal components of the module may be aged or burned. A stable power supply should be configured.
