RS232 / 485 Interface Module: This device features four RS232 / 485 interfaces, with a particularly well-designed isolated RS485 interface to ensure the safety of both the integrated unit and the monitored equipment. The isolated RS485 interface uses TI's ISO3082 chip, effectively isolating the integrated unit from the ground wire of the monitored equipment. Due to the broken ground loop, this type of device can operate over a much wider common-mode voltage range, making it ideal for long-distance transmission lines. Testing has shown that the device's symmetrical isolation layer provides 2500VRMS isolation for 60 seconds between the bus transceiver and the logic level interface, according to UL1577 standards. All wired I / O is susceptible to electrical transient noise from various signal sources. If the amplitude and duration of these transients are sufficient, they can damage the transceiver or nearby sensitive circuitry. This isolation device significantly improves protection levels and reduces the risk of damage to expensive control circuitry.

[0092] The equipment stores monitoring indicator data locally for a period of no less than 60 days; it can also upload data for a specified time period to the management platform for data synchronization according to instructions from the management platform.

[0093] To further enhance the heat dissipation function during equipment operation, a heat dissipation device is also installed inside the housing, with its heat dissipation vents located on the bottom or side of the housing. In this embodiment, both the front and rear panels are provided with several evenly arranged heat dissipation holes to facilitate heat dissipation from the interior of the housing.
