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.
Operating temperature: It can operate in the temperature range of -22 to 150°F (-30 to 65°C).
Interfaces and connections: The CFP-1804’s interfaces and universal connections can be configured as input or output modules.
Communication: The CFP-1804 Ethernet/serial backplane can connect Compact FieldPoint I/O modules to high-speed Ethernet networks or RS232 serial ports. It also supports a wide range of third-party protocols such as Modbus TCP, Optomux, Modbus ASCII, Modbus RTU, and OPC, as well as NI event-driven Ethernet/serial protocols.
Configuration: IP address assignment and module configuration can be done using the NI Measurement & Automation Explorer (MAX) and Ni-FieldPoint drivers.
Input function: It can receive digital or analog signal input from various sensors or devices, such as temperature, pressure, flow, etc., for monitoring various parameters in industrial processes.
Output function: can control a variety of actuators or equipment, such as electric valves, motors, lights, etc., through the output of digital or analog signals, to achieve the control and regulation of industrial processes.
High-speed data exchange: Possible support for high-speed data exchange, the ability to quickly receive and send data, ensuring real-time monitoring and control.
Multiple interfaces: May be equipped with a variety of communication interfaces, such as Ethernet, serial interface, etc., data communication and integration with other devices or control systems.
Programmability: May have a certain degree of programmability, users can configure the input and output channel parameters and functions according to actual needs.
Function: Usually used to monitor the vibration level and shaft displacement of mechanical equipment (such as engines, turbines, pumps, etc.). It can monitor the vibration level, frequency and axial displacement of the equipment in real time, and issue an alarm or take corresponding protective measures according to the preset alarm threshold.
Measurement parameters: can measure vibration parameters, such as vibration speed, vibration acceleration, vibration displacement, etc., can also measure axis displacement parameters, such as axis offset, radial displacement, etc.
Input signal range: +0.8V to -21.0V for non-isolated I/O modules; For isolated I/O modules, the range is +5V to -11V.
Power consumption: Typical power consumption is 3.2 watts.
