Measurement accuracy: 100 (the specific unit or meaning may vary depending on the application scenario)
Measurement range: 100 (again, the specific unit or meaning may vary depending on the application scenario)
Interface type: Supports a variety of interfaces, including input and output interfaces, to connect with control or detection components and executive components in industrial sites
Features:
Receive the input signal given by the control target, and calculate and output the result according to the program content set by the user
Operation results and program information can be saved in the internal output area, or extracted or set as other information by an externally connected device
Equipped with Modbus gateway function (modbus-TCP ≈ modbus-RTU protocol conversion function)
High speed counter (100kHz) x 5 channels, pulse /PWM output (65kHz) x 3 channels
Communication interface: Supports a wide range of serial (RS232/RS422/RS485) and Ethernet TCP/IP communication functions.
Supported protocols include the Modicon Modbus protocol (via serial communication), the Modbus/TCP protocol (serial Modbus variant for TCP/IP Ethernet communication), and the proprietary Bently Nevada protocol (for communication with 3500 rack configuration and data acquisition packages).
Power requirements: For Modbus RS232/RS422 I/O modules, the typical power consumption is 5 watts; For the Modbus RS485 I/O module, the typical power consumption is 5.6 watts.
Data refresh time: The data acquisition rate depends on the frame configuration, but the refresh time cannot exceed 1 second for all modules in the 3500 frame.
