Product Short Description
Product Name: Compact FieldPoint cFP-1808 Ethernet/Serial Network Interface
Product Introduction: The NI cFP-1808 is a ruggedized Ethernet and serial network interface module belonging to the Compact FieldPoint family, designed to connect FieldPoint I/O modules to Ethernet networks or serial communication systems for distributed measurement and control applications. It acts as the communication bridge between the controller system and the I/O modules in industrial environments.
Description
Technical Specifications:
- Network Interface: 10BaseT and 100BaseTX Ethernet, IEEE 802.3 compliant
- Communication Rate: 10 or 100 Mb/s, autonegotiated
- Maximum Cabling Distance: 100 m per segment
- Serial Port: One RS-232 (DCE) port, 300 to 115,200 b/s baud rate, 8 data bits, 1 stop bit, no parity, no flow control
- Power Supply Range: 11 to 30 VDC
- Recommended Power Supply: 20 W
- Power Consumption: 6.1 W plus I/O module power
- Maximum Power to I/O Modules: 9 W
- Isolation Voltage: 250 Vrms continuous (Measurement Category II), 2,300 Vrms withstand for 5 seconds
- Weight: 1,595 g (3 lb 8 oz)
Functional Features: The module supports autonegotiated 10/100 Mbps Ethernet communication and provides an RS-232 serial interface for legacy device integration. It delivers 9 W of power to connected I/O modules and can support multiple I/O banks depending on network topology. The green POWER and STATUS indicators provide visual operational feedback.
Application Scenarios: Suitable for distributed I/O systems in factory automation, process monitoring, and industrial control systems requiring ruggedized Ethernet connectivity in harsh environments.
Environmental Parameters:
- Operating Temperature: -40 to 70 °C
- Storage Temperature: -55 to 85 °C
- Relative Humidity: 10 to 90%, noncondensing
- Maximum Altitude: 2,000 m
- Vibration: Random 5 grms (10–500 Hz), Sinusoidal 5 g (10–500 Hz)
- Shock: 50 g, 3 ms half sine
Material/Structural Characteristics: The module uses screw-terminal wiring compatible with 14 to 22 AWG copper wire with 7 mm insulation stripping. The terminal torque specification is 0.5 to 0.6 N·m. The unit is designed to meet IEC 61010-1, EN 61010-1, UL 61010-1, and CAN/CSA-C22.2 No. 61010-1 safety standards, with EN 55011 Class A emissions compliance.
Working Principle: The cFP-1808 serves as a network interface controller that manages communication between the Ethernet network and the connected FieldPoint I/O modules. It performs power-on self-test (POST) on startup and uses shared variables to access distributed I/O channels.
Installation Requirements:
- Mount on DIN rail, panel, or 19-inch rack using appropriate mounting hardware
- Connect the protective earth (PE) ground terminal to system safety ground using 14 AWG wire with ring lug
- Maintain at least 51 mm clearance around the unit for air circulation
- Keep 38 mm below and 51 mm above I/O modules for cooling
- When using UL Recognized I/O modules, install the entire system in a suitably rated UL Listed NEMA or IP enclosure
Usage Precautions:
- FieldPoint modules are intended for indoor use only; for outdoor use, install in a suitable sealed enclosure
- Do not remove or add connector blocks when power is connected
- Avoid contact between body and connector block signal wiring during hot-swapping
- Use shielded cabling for EMC compliance
- For hazardous locations, refer to product label certifications
