Description

cFP-2110: Product Overview
The National Instruments cFP-2110 is a 16-channel sinking digital input module designed for the Compact FieldPoint distributed I/O platform, providing industrial-grade digital sensing capability for harsh environment applications. This module functions as an interface between field devices such as proximity switches, limit switches, and push buttons, and the central control system, converting 24V DC field signals to logic levels readable by the controller. The module is designed for deployment in industrial environments where reliable status monitoring of digital devices is required.
As part of the Compact FieldPoint system, this module installs directly into a Compact FieldPoint I/O base unit, which provides the communication interface to a network and power distribution. Each of the 16 input channels is opto-isolated, providing 4 kV electrical isolation between field wiring and the internal logic circuits. This isolation protects the control system from voltage transients, ground loops, and other electrical noise commonly found in industrial settings. The module supports a wide input voltage range from 10V to 30V DC, making it compatible with standard 24V industrial control components.
The Compact FieldPoint platform provides a rugged, distributed I/O solution suitable for applications where I/O points are located far from the central controller or in environmentally challenging locations. The modules are designed to operate in extended temperature ranges and withstand vibration, making them suitable for direct machine mounting. The system supports various network protocols including Ethernet, serial, and fieldbus options, providing flexibility in system architecture.

Core Features & Customer Value
Industrial-Grade Reliability: The 4 kV channel-to-bus isolation provides critical protection for the control system against voltage transients and ground potential differences that can occur in industrial environments. This high level of isolation ensures reliable operation in applications involving long cable runs or multiple grounding points, significantly reducing downtime caused by electrical noise or wiring faults. The wide operating temperature range allows deployment in unheated enclosures or outdoor locations.
High-Density Channel Configuration: The 16-channel design provides significant I/O capability in a single module slot, reducing the number of modules required for applications with numerous digital sensors. This high channel density is particularly valuable in machine control applications where multiple limit switches, proximity sensors, and status indicators need to be monitored. The compact form factor maximizes I/O points per unit volume, important in space-constrained control panels.
Rugged Environmental Specifications: The module meets stringent vibration and shock immunity requirements, making it suitable for direct mounting on machinery or in mobile equipment. The extended temperature range ensures reliable operation in harsh environments from factory floors to outdoor installations. This robustness reduces maintenance requirements and extends service life in demanding applications.
Typical Applications
In automated manufacturing systems, the module monitors the status of multiple limit switches, photoelectric sensors, and emergency stop buttons distributed throughout a production machine. The high channel count allows comprehensive machine status monitoring while the isolation protects against electrical noise from motor drives and power equipment.
For material handling equipment, the inputs track package presence sensors, door interlock switches, and safety curtain monitors on conveyor systems and automated guided vehicles. The wide operating temperature range ensures reliable performance in warehouse environments subject to temperature variations.
In building automation systems, the module monitors security door contacts, occupancy sensors, and equipment status points distributed throughout a facility. The distributed architecture allows placement near field devices, reducing wiring costs compared to centralized I/O systems.
