1756-L72  性能参数plc

1756-L72 Performance parameters plc requires the ambient temperature of 0~55℃, installation can not be placed under the heat of the elements, the surrounding ventilation and heat dissipation space should be large enough, the basic unit and the expansion unit should have more than 30mm between; The upper and lower parts of the switchgear should have ventilated shutters to prevent direct sunlight exposure; If the surrounding environment is over 55 ° C, it is necessary to install an electric fan for forced ventilation. ?? 2. Humidity?? In order to ensure the insulation performance of the plc, the relative humidity of the air should be less than 85% (no condensation). ?? 3. Vibration?? The plc should be kept away from the strong vibration source to prevent frequent or continuous vibration with a vibration frequency of 10~55hz. When the use of the environment can not avoid vibration, shock absorption measures must be taken, such as the use of shock absorption glue. 1756-L72 Performance parameters?? 4. The air? Avoid corrosive and flammable gases, such as hydrogen chloride, hydrogen sulfide, etc. For the environment with more dust or corrosive gases in the air, the plc can be installed in a better closed control room or control cabinet, and the air purification device is installed.

The AMAX-2700 series is a module designed to augment digital input and exit points for AMONet high-speed RS-485. Its high-speed, flexible and cost-effective features provide a rigorous solution for machine equipment manufacturers. There are four main types of digital input/output modules, including 32 point input, 32 point output, 16 point input/output and 8 point output/input. With these modules, the sensor/sensor can be connected directly to the module without the need for additional switching boards. 1756-L72 Performance parameters Input/output points can be connected up to 100 meters long, AMONet high-speed RS-485 combines the characteristics of simplicity, wiring saving and high speed, can scan 2048 input/output channels in 1.04 milliseconds, and thanks to its integrated pluggable wiring terminal design, engineers have less time to install and maintain operations.
