As a trusted industrial automation solutions provider since 2011, Rossonix Co., Limited presents its precision-engineered 12-Bit Resolution Analog Output Module with RS-485 Interface. Designed for mission-critical applications, this module delivers exceptional signal accuracy and robust communication capabilities in harsh industrial environments. With ISO-certified manufacturing processes and a global presence spanning North America, Europe, and Asia, we ensure reliable performance that meets international standards.
This advanced module converts digital control signals to precise analog outputs with 12-bit resolution, enabling fine-grained process control. The integrated RS-485 interface supports long-distance communication (up to 1200 meters) with inherent noise immunity, making it ideal for distributed control systems. Key applications include:
- Process control systems
- SCADA networks
- Industrial IoT deployments
- Test and measurement equipment
- Manufacturing execution systems
Technical Specifications:
| Parameter | Specification |
| Resolution | 12-bit (4096 steps) |
| Output Channels | 4 isolated channels |
| Output Range | 0-10V, ±10V, 0-20mA, 4-20mA (software selectable) |
| Update Rate | 100 samples/second per channel |
| Communication Protocol | Modbus RTU over RS-485 |
| Isolation Voltage | 2500V AC between channels and bus |
Key Advantages:
- Enhanced Accuracy: ±0.1% FSR accuracy ensures precise control signal generation
- Noise Immunity: Differential signaling eliminates ground loop issues
- Scalable Architecture: Supports up to 32 devices on a single RS-485 bus
- Industrial Durability: -20°C to 70°C operating range with 85% RH non-condensing
- Zero-Configuration: Automatic baud rate detection (9600 to 115200 bps)
Backed by Rossonix's decade-long expertise in industrial automation and supported by overseas offices, this module undergoes rigorous quality control through our ISO9001-certified processes. With over US$5 million annual export value and shipments from Shenzhen, Hong Kong, and European ports, we deliver to all major global markets including North America, Europe, and Asia. The module's modular design allows seamless integration with existing PLC systems while its compact form factor (110mm x 70mm x 35mm) saves valuable control panel space.
Frequently Asked Questions:
Q: What does 12-bit resolution mean for analog outputs?
A: 12-bit resolution provides 4096 discrete steps between minimum and maximum output values, enabling finer control than lower-resolution modules (e.g., 10-bit offers only 1024 steps).
Q: Can this module operate in high-electrical-noise environments?
A: Yes, the differential RS-485 signaling and 2500V isolation provide excellent noise immunity, making it suitable for use near motors, VFDs, and welding equipment.
Q: What power supply is required?
A: It operates on 24V DC with low power consumption (typically 3W). Reverse polarity protection is included.
Q: Is software included with the module?
A: We provide Modbus register maps and sample code for major PLC platforms. No proprietary software is required.
Q: How are output ranges configured?
A: Each channel can be independently configured via software for voltage (0-10V, ±10V) or current (0-20mA, 4-20mA) output without hardware changes.
Q: What is the lead time for orders?
A: Standard products ship within 3-5 working days from Shenzhen or Hong Kong ports. Bulk orders may qualify for express shipping.
