REXRTOH BTV04.2GN-FW Bus Terminal Valve

The REXRTOH BTV04.2GN-FW represents a significant evolution in pneumatic control technology, combining valve functionality, network connectivity, and intelligent sensor/actuator management in a single, compact device. As a Bus Terminal Valve (BTV), it decentralizes control by moving the valve manifold directly to the point of action on the machine. This unit is specifically equipped with a PROFINET interface, an integrated IO-Link master, and electronic pressure regulation (EPR), making it a cornerstone for Industry 4.0-ready pneumatic systems that demand flexibility, diagnostics, and reduced wiring complexity.

Key Features and Technological Advantages

The BTV04.2GN-FW is packed with features that streamline automation design and operation:

• PROFINET Connectivity: Integrates seamlessly into modern Ethernet-based automation architectures, offering fast cycle times and easy configuration via GSDML files.

• Integrated IO-Link Master: Provides a standardized point-to-point serial communication channel (IO-Link) for connecting up to a defined number of IO-Link devices, enabling bidirectional data exchange beyond simple on/off signals.

• Electronic Pressure Regulation (EPR): Allows for precise, digital setting and closed-loop control of supply pressure for connected pneumatic actuators directly from the PLC software, enabling dynamic pressure adjustment and recipe management.

• Modular Valve Design: The unit is based on a modular platform where individual valve slices (e.g., 5/2-way, 3/2-way) can be combined to create a custom valve manifold tailored to the application's needs.

• Comprehensive Diagnostics: Provides detailed status information for each valve (e.g., switching cycle count, coil temperature, electrical faults) and connected IO-Link devices, facilitating predictive maintenance.

• Compact and Robust Housing: Designed for direct mounting on machines, even in harsh environments, with a high degree of protection (typically IP65).

• Firmware "FW": The specific firmware version enables advanced functionalities, such as enhanced diagnostic features, support for PROFINET profiles, and parameter backup/restore capabilities.

• Reduced Wiring Effort: Dramatically cuts installation time and cost by replacing extensive multi-core cables with a single network cable and short IO-Link cables to devices.
