Industrial-Grade Signal Routing: Reliable Performance for PLC & Precision Data Acquisition

Stable and reliable analog signal routing is critical for PLC systems and high-precision data acquisition in industrial automation. Ruimeng Technology introduces the MSG408 (8-Ch Single-Ended) and MSG409 (4-Ch Differential) high-performance analog multiplexers, delivering robust signal switching solutions through four core technological advantages.

Performance Breakthrough: Four Core Advantages

1. Wide Voltage Operation (±5V to ±20V Dual Supply)

• Supports broad dual-supply range, compatible with multiple system voltage architectures

• Analog input range covers VSS to VDD, handling full-scale signals seamlessly

• Enhances design flexibility for high-voltage applications

2. Low Ron & High-Speed Switching

• Ultra-low on-resistance (Ron): Minimizes signal attenuation/distortion

• High-speed switching: Meets timing requirements for real-time control & high-speed DAQ

• Ensures signal fidelity and system efficiency

3. BBM (Break-Before-Make) Safety Mechanism

• Channel switching logic: Breaks existing connection before making new contact

• Eliminates cross-channel short-circuit risks during switching

• Protects sensitive signal sources and downstream circuitry

• Critical reliability safeguard against potential failures

4. Flexible Digital Control Interface

• MSG408: 3-bit binary address (A0,A1,A2) for 8:1 single-ended channel selection

• MSG409: 2-bit binary address (A0,A1) for 4:1 differential pair selection

• Independent enable (EN): Active-low global shutdown for power saving/safety isolation

• Simplified system integration with robust control logic
