Feature

●Reliable Performance: This large LED screen wall clock displays temperature, humidity, and time statically, ensuring no flickering. It also features a perpetual calendar display for year, month, day, week, hour, and minute.
●Flexible Sensors: Imported sensors are used, with temperature accuracy of ± 0.4 ℃ and humidity accuracy of ± 2% RH, stable and reliable performance.
●Good Features: The clock uses a 485 communication interface with a standard RTU communication protocol, allowing for address and baud rate customization. It can communicate up to 2000 meters.
●Alarm and Hysteresis Values: The upper and lower limits of alarm and hysteresis values can be set. If the limit value is exceeded, an audible and visual alarm (optional) can be given. The device can quickly modify the value by pressing the button, which
●Installation Position: This clock can be easily installed on walls and hung up, making it suitable for various on-site environments.

Note:Standby cannot be connected to PLC or computerPossible causes:1) The computer has multiple COM ports, and the selected port is incorrect.2) The device address is incorrect, or there is a device with duplicate address (factory default value is 1).3) Baud rate, check mode, data bit, stop bit error.4) The polling interval and response waiting time of the host are too short, and both need to be set to more than 200ms.5) 485 bus is disconnected, or A line and B line are reversed.6)
