6ES7322-1BH01-0AA0 New Original Siemens S7-300 Plc Programming Controller module

2. Key Selling Points

1. 16-Channel Relay Outputs with High Load Capacity:Features 16 independent relay outputs, each capable of switching up to 2A at 250V AC or 30V DC, ideal for directly driving contactors, solenoids, lamps, and small motors.

2. Galvanic Isolation for Strong Noise Immunity:Provides opto-isolation (500V AC) between field side and backplane bus, protecting the CPU from electrical surges and interference from the plant floor.

3. AC/DC Load Compatibility for Flexible Applications:Relay contacts are polarity-free, supporting both AC and DC loads, making it highly versatile for diverse industrial applications.

4. Reliable Contacts for Low-to-Medium Frequency Switching:With a mechanical life of over 100,000 operations, it is well-suited for applications requiring high reliability but not high switching speed (e.g., start/stop, interlocks).

5. LED Indicators for Real-Time Status & Diagnostics:Each output has a green LED to show active status; front panel includes RUN and ERROR LEDs for immediate visual feedback during commissioning and maintenance.
