Overview
The
Red Lion PAXCDC40 is a Modbus communications option card with a terminal block connection. It is designed specifically for Red Lion PAX series panel meters and supports RS-485 RTU and ASCII Modbus communication modes.RS-485ModbusRTU/ASCII
When installed in a compatible PAX panel meter, the card can send display values, set points, and reset values through Modbus RS-485 communication. It is used in the serial communications option category, with one option card allowed per category in the meter.
🔁 Modbus Communication for PAX Meters
Protocol Support: RS-485 RTU and ASCII Modbus modes.
Address Range: Supports Modbus addresses from 1 to 247.
Data Access: Transmits display values, set points, and reset values from compatible PAX meters.
Key Features
- Terminal block connection: straightforward wiring for control panel installations
- 300 to 38400 baud rate: supports multiple communication speeds
- 7/8 bit data format: configurable to match the Modbus network setup
- No, odd, or even parity: flexible serial communication setup
- Programmable transmit delay: helps coordinate network timing
- PAX series compatibility: made for Red Lion PAX panel meter option slots
✅ Designed for Modbus Data Integration
The PAXCDC40 adds Modbus RS-485 communication to a PAX panel meter, making it useful for automation systems that need meter values and setpoint data over a Modbus network.
Applications
The PAXCDC40 is ideal for applications that require Modbus communication from a PAX series panel meter:
- Modbus RS-485 control networks
- PLC and HMI meter data integration
- Industrial process monitoring
- Display value and setpoint reporting
- Panel meter communication upgrades
⚠️ Important Installation Info
Compatibility: Use only with compatible Red Lion PAX series panel meters.
Option Card Limit: Only one serial communications option card can be used in the panel meter at one time.
Network Setup: Match baud rate, parity, addressing, and protocol mode to the connected Modbus network.
Performance Benefits
- Adds Modbus communication without replacing the existing meter
- Supports both RTU and ASCII Modbus modes
- Programmable settings simplify network integration
- Allows PAX meter values and setpoint data to be shared with automation systems
