The 6ES7323-1BL00-0AA0 is a versatile digital combo module from Siemens. It belongs to the SIMATIC S7-300 product family. This SM 323 module integrates 16 digital inputs and 16 digital outputs. It provides a compact and cost-effective I/O solution. Each channel is optically isolated for enhanced signal integrity. The module operates reliably across a wide temperature range. Its design supports both horizontal and vertical installation. This makes it suitable for various industrial automation applications.
The Siemens 6ES7323-1BL00-0AA0 requires a 24V DC load voltage. The permissible range is from 20.4V to 28.8V DC. It draws a maximum of 80 mA from the load supply without load. It also consumes 80 mA from the backplane bus. Typical power loss for this SM 323 is 6.5 W.
For the digital inputs, there are 16 channels available. They comply with type 1 according to IEC 61131. The input voltage rating is 24V DC. Typical input current is 7 mA per channel. Input delay ranges from 1.2 ms to 4.8 ms for both transitions. For cable connections, shielded cables can run up to 1000 meters. Unshielded cables are limited to 600 meters.
The total current per output group varies with temperature. For horizontal installation at 40°C, the maximum is 4 A. At 60°C, it drops to 3 A. For vertical installation, the maximum is 2 A at 40°C. At 60°C for vertical mounting, it is 1 A. These limits ensure reliable operation under all conditions.
The number of simultaneously controllable inputs also depends on temperature. Up to 40°C, you can use all 16 inputs. Up to 60°C, the limit is 8 inputs. This derating ensures thermal stability.
The 6ES7323-1BL00-0AA0 provides optical isolation for both inputs and outputs. The digital inputs are isolated in groups of 16. The digital outputs are isolated in groups of 8. Additionally, isolation exists between channels and the backplane bus. This protects your system from electrical interference.
Diagnostic indication is provided via green LEDs. Each input and output channel has its own status indicator. However, this module does not support diagnostic alarms. It does not offer isochronous mode either.
Follow these steps for a successful installation.
First, ensure the S7-300 rack is de-energized.
Next, mount the 6ES7323-1BL00-0AA0 onto the rail.
Then, connect it to adjacent modules using the bus connector.
After that, attach the 24V DC supply to the front connector.
Finally, wire your field devices to the 40-pin front connector.
Always observe the current derating curves for your installation. Use shielded cables for long runs to reduce noise. Ensure proper grounding to maintain signal quality.
The package includes the following items:
6ES7323-1BL00-0AA0 digital I/O module (1 unit)
40-pin front connector (1 unit)
