2. Key Selling Points

1. 16 Relay Output Channels with High Drive Capacity:Provides 16 independent relay contact outputs, each capable of handling 2 A @ 250 V AC / 30 V DC, suitable for directly driving solenoids, contactors, indicator lights, and other high-power loads.
2. Supports Mixed AC/DC Loads:Relay outputs are polarity-free and can control both AC and DC loads, ideal for multi-power systems or complex control applications, enhancing wiring flexibility.
3. Plug-and-Play, Right-Side Expansion Design:Installs directly to the right side of M221/M241 CPU modules, requires no additional power or communication cables, and is automatically recognized—ensuring fast and tool-free installation.
4. LED Status Indicators for Easy Diagnostics:Each output channel features an LED indicator showing real-time status—ideal for on-site commissioning, troubleshooting, and maintenance.
5. Electrical Isolation for Strong Noise Immunity:Features opto-isolation between output channels and backplane bus, effectively preventing EMI and voltage feedback—ensuring signal stability and reliability.
6. Industrial-Grade Reliability:Operates from -25°C to +60°C, certified to CE and UL standards—suitable for harsh industrial environments (high temperature, humidity, strong EMI).
