1. Main Specifications| Product Series | Modicon TM3 Expansion Module | | Product Type | Digital Input/Output Module | | Dimensions (H × W × D) | 90 mm × 54.8 mm × 84.6 mm | | Digital Quantity Output (DQ) | 16 Points | | Output Type | Relay Output | | Voltage Level | 24 V DC |
2. Key Selling Points16 DI + 16 Relay DQ, High-Density Integration:Integrates 16 digital inputs and 16 relay outputs in a single module—reducing module count and saving panel
space, ideal for systems with high I/O requirements. Relay Outputs for AC/DC Load Compatibility:Features dry-contact relay outputs that can control both AC (e.g., contactors, lamps) and DC (e.g., solenoids, relays) loads without polarity concerns—offering flexible wiring options. High Drive Capacity: 2 A per Point:Each output supports up to 2 A @ 250 V AC / 30 V DC, capable of directly driving small-to-medium actuators (e.g.,
contactor coils, heaters, alarms)—eliminating the need for
intermediate relays. Plug-and-Play, Right-Side Expansion: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. LED Status Indicators per Channel:All 32 I/O points have individual LED indicators for real-time status monitoring—great for commissioning,
troubleshooting, and maintenance. Electrical Isolation for Strong Noise Immunity:Both input and output channels are optically isolated from the backplane bus, effectively preventing electrical
noise and voltage feedback, enhancing system reliability.
