16 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.
