6ES7288-2DR32-0AA0 Original Siemens S7-200 SMART Plc Programming Controller module

2. Key Selling Points

1. 32-Channel Relay Outputs – High-Density I/O Expansion:Provides 32 independent digital output points in one module, ideal for systems requiring extensive control outputs.

2. Dry-Contact Relay Outputs – AC/DC Load Compatibility:Features potential-free contacts that can switch both AC (e.g., 220V AC) and DC (e.g., 24V DC) loads, offering maximum wiring flexibility.

3. High Drive Capacity – Up to 2A per Point:Each relay contact can handle up to 2A current, enabling direct control of contactors, solenoids, lamps, and small motors without additional relays.

4. Group-Based Optical Isolation – Strong Noise Immunity:Outputs are divided into 4 isolated groups (8 points each), with optical isolation between groups and from the CPU, reducing electrical interference.

5. Per-Channel LED Indicators – Clear Status Feedback:Each output has a green LED for real-time visual indication, facilitating commissioning, monitoring, and troubleshooting.
