The Festo CPX-F8DE-P is a high-performance 8-channel digital input module designed to integrate seamlessly into Festo’s CPX automation platform. Engineered for reliable signal acquisition in industrial environments, this module ensures safe, accurate, and efficient input monitoring for automation systems. Ideal for machine builders and plant operators, it helps you streamline diagnostics, enhance safety compliance, and reduce downtime.
Whether you’re upgrading a modular control system or deploying new automation infrastructure, the CPX-F8DE-P offers robust signal detection, fail-safe operation, and comprehensive diagnostics—all critical for Industry 4.0-ready smart factories.
The CPX-F8DE-P is the unsung hero behind intelligent machines—it enables rapid, safe, and reliable signal detection in automation systems where every millisecond counts. It’s not just another input module; it’s your gateway to fail-safe operations, smart diagnostics, and scalable modular control, all in a palm-sized package.
In complex automation setups, unreliable signal monitoring leads to system errors, unplanned downtime, and safety risks. The CPX-F8DE-P solves this by delivering robust input diagnostics, high-integrity signal detection, and fail-safe communication—giving engineers total visibility and control in high-stakes industrial environments
Reliable Input Detection with Safety Compliance
Designed to meet SIL 3 (EN 61508/EN 62061) and PL e (ISO 13849) standards, the CPX-F8DE-P ensures high-integrity input signal acquisition in safety-critical applications. This makes it an excellent choice for systems requiring high diagnostic coverage and fail-safe behavior.
Eight Individually Monitored Channels
The module offers 8 PNP input channels, each capable of detecting wire breaks, short circuits, overvoltage, undervoltage, and process errors. With LED indicators per channel, operators gain real-time visibility into the module’s performance, enabling fast troubleshooting and minimal downtime.
Seamless Integration with Festo CPX Platform
As part of the CPX modular system, this input module supports tool-free installation, plug-and-play configuration, and standardized communication protocols. Whether used in centralized control cabinets or distributed I/O setups, it simplifies scalability in both small and large automation projects.
Rugged & Compact Design
With dimensions of just 50 x 107 x 55 mm and a weight of 46 g, the CPX-F8DE-P is ideal for space-constrained applications. Its IP rating depends on the chosen manifold block, allowing users to match protection levels to the installation environment.
Wide Voltage and Temperature Range
Operates reliably across 20.4 V to 28.8 V DC and temperatures from -5°C to +50°C, making it suitable for diverse industrial sectors, including automotive, packaging, food & beverage, and electronics.
Industrial-Grade Compliance and Certifications
CE and UKCA marked for EMC, machinery, and RoHS compliance
TÜV-certified and c UL us Recognized for North American standards
Complies with IEC 61131-2 Type 2 input standards
Manufacturer Part Number: Festo 2597424

Key Features:
Emergency Stop Circuit Monitoring
In safety-critical environments, dual emergency-stop buttons wired to the CPX-F8DE-P ensure reliable detection of operator-initiated shutdowns. The module’s ability to detect short circuits and wire breaks on individual channels provides assurance that any E-stop event is captured and executed safely. Its built-in diagnostics trigger immediate safe-state transitions in case of faults, helping prevent unsafe machine operation.
Guard Door Safety Interlock
When used to monitor interlocked safety doors, the CPX-F8DE-P validates signal integrity from dual-channel OSSDs. It instantly identifies mismatches or signal interruptions—such as when a door is opened—ensuring that machines halt safely. The module’s compliance with high-level safety standards makes it ideal for use in manufacturing cells where human access points require strict control and fault tolerance.
Two-Hand Control Start System
To prevent accidental or one-handed machine activation, two control buttons are connected to the CPX-F8DE-P using a safety input pair configuration. The module verifies both inputs are triggered simultaneously and within a defined time window. If the sequence fails, it prevents the start command, ensuring the operator’s hands are safely positioned—critical in press machines or robotic cells.
Dual Access Door Monitoring on Shared Channels
In systems where multiple safety doors must be monitored, the CPX-F8DE-P allows two sensors to share one input pair without compromising diagnostic capabilities. The module identifies electrical faults like cross-wiring and channel mismatches, reducing the number of input modules required. This compact setup is ideal for large enclosures or assembly lines with multiple access points.
Flexible Sensor Input in Distributed Systems
The CPX-F8DE-P supports multiple two-wire sensors, such as level switches and photoelectric sensors, across its eight input channels. It ensures each signal meets electrical standards and flags inconsistencies like undervoltage or unexpected signal loss. Its long cable length support and per-channel diagnostics are especially valuable in distributed systems, where physical access for maintenance may be limited.
