Key Features
- Wireless Connectivity – Eliminates long cable runs between PLCs and sensors.
- 08 Channel Digital I/O – Supports up to 08 independent digital inputs/outputs and a separate input for battery low alarm in case the module is battery powered.
- Configurable Address & Frequency – DIP-switch programming for address (A000–255) and channel (F000–125).
- High-Speed Response – < 10 ms signal update time with RF retry and acknowledgment mechanisms.
- Live 7-Segment Display – Displays address, frequency, and error codes in real time.
- Healthy Signal (HSO) Output – Indicates stable communication between Tx & Rx modules at both ends.
- Emergency Stop (ES) Input – Provides immediate system halt and safely locks inputs during faults.
- Isolation Mode – Diagnostic feature to silence a module during troubleshooting.
- Secure Communication – Unique address encryption and collision detection prevent cross-talk.
Advanced Wireless Communication
The RFST C-Series utilizes intelligent wireless communication protocols to ensure dependable industrial operation.
- Configurable Address Range
- Configurable Frequency Channels
- Address encryption for secure communication
- Automatic RF noise and collision detection

Industrial Safety Features
The module is equipped with multiple safety mechanisms designed for industrial environments.
Healthy Signal (HS)
Dedicated Healthy Signal outputs on both transmitter and receiver continuously monitor communication status. In case of communication failure, the signal changes state, allowing PLC interlocking and fault handling.
Emergency Signal (ES)
Emergency inputs on both transmitter and receiver instantly halt communication and place the system into a safe condition when activated.
Isolation Mode
Built-in isolation mode allows the module to become completely radio silent for troubleshooting and maintenance operations.
Easy Configuration
No software is required for setup or commissioning.
Configuration is performed directly on the module using DIP switches and the integrated display for:
- Address assignment
- Frequency selection
- Fool-proof Pairing and commissioning
- Troubleshooting and diagnostics
Reliable Communication Range
- Up to 30 meters in typical factory environments
- Up to 100 meters in open line-of-sight conditions
- Expandable using Projexel repeaters for extended coverage
Typical Applications
- ASRS (Automated Storage and Retrieval Systems)
- Vertical Lift Modules (VLM)
- Industrial Robots
- Transfer Cars
- Rotary Indexing Machines
- Gantry Systems
- Material Handling Equipment
- Packaging Machines
- Conveyor Systems
- Special Purpose Machines (SPMs)
