The Phoenix Contact PLC-V8C/PT-24DC/RS485 is a powerful and compact logic module that bridges the gap between traditional control relays and full-scale PLCs. As part of the PLC logic relay system, it uniquely integrates the logic, interface, and field connection levels into a single, space-saving solution, making it ideal for small to medium-sized automation tasks.

Compact Design and I/O Flexibility

With a width of just 50 mm, the PLC-V8C provides a full 16 I/O signals, with 8 digital inputs (2 of which can be configured as 0-10V analog inputs) and 8 solid-state outputs. The system's true power lies in its modular expandability. Using extension modules like the PLC-V8C/PT-24DC/EM, the I/O count can be increased to a maximum of 48 points (with up to 2 extension modules), allowing the system to grow with application needs without requiring a complete controller replacement.

Seamless Integration and Communication

Networking is a key strength of the PLC-V8C. It features an RS-485 interface supporting the Modbus/RTU protocol, enabling easy and reliable integration with higher-level controllers, HMIs, and other industrial equipment. A micro USB port provides a simple connection for programming and configuration. For advanced connectivity, the controller can accommodate a Bluetooth adapter for wireless communication or a memory module for program backup and transfer.

Simplified Engineering with LOGIC+

The PLC logic system is programmed using the intuitive LOGIC+ software. This free software tool supports both flowchart and relay ladder logic (RLL) programming styles, making it accessible to users with varying levels of experience. It includes a comprehensive library of ready-to-use function blocks for timers, counters, threshold switches, and more, significantly reducing engineering time. The software is based on IEC 61131-3 standards, ensuring a professional and universal programming environment.

Rugged and Reliable Operation

Designed for industrial environments, the PLC-V8C operates reliably within a temperature range of -20°C to +50°C and is rated to IP20. It features a real-time clock with a 96-hour capacitive buffer for accurate time-stamping of events. The device is certified to international standards including CE, cUL, cULus, and EAC, ensuring compliance and safety for global applications. The push-in connection technology further enhances reliability by providing a fast, vibration-proof, and maintenance-free wiring solution.

Applications

The Phoenix Contact PLC-V8C is ideally suited for a wide range of discrete and analog control applications, including:

• Small machine control and building automation (lighting, HVAC)
• Conveyor systems and material handling
• Pump control and valve sequencing
• Access control and gate systems
• Packaging and labeling machinery
