Description
The NI cFP-CB-4 Compact FieldPoint Probeable Connector Block, with the part number 780017-04, features a removable connector that includes 20 screw terminals for efficient wiring and signal connection.
This connector block is designed for mounting on the cFP-BP-x or cFP-180x Compact FieldPoint Backplane, making it ideal for various applications such as linking sensors and actuators, prototyping, and troubleshooting.
For environments with hazardous voltage or high vibration, it is highly recommended to use wire ferrules on signal wires to ensure safety and reliability. The connector block incorporates V terminals for VSUP and C terminals for COM, each set being internally connected to provide a streamlined wiring process.
When attaching wires, a flathead screwdriver with a blade size of less than 0.09 x 0.04 inches is needed, and users should strip approximately 0.35 inches of insulation from the wire ends. The screw terminals should be securely fastened with a torque of 0.22–0.25 N · m (1.9–2.2 lb · in.) to ensure a proper connection.
The cFP-CB-4 includes 4 built-in CJC (Cold Junction Compensation) sensors to maintain accuracy in temperature measurements, with a typical cold-junction accuracy of 0.15 °C and a maximum of 0.3 °C. Weighing 5.0 oz, this connector block is built to withstand operating temperature ranges from -40°C to 70°C and is suitable for various industrial environments.
