6ES7322-1FH00-0AA0 New Original Siemens S7-300 Plc Programming Controller module

2. Key Selling Points

1. 8-Channel Analog Output Module for S7-300 Series: Model SM 332, AO 8×U/I High-Speed, designed for the SIMATIC S7-300 PLC system, provides 8 high-precision analog voltage/current outputs—ideal for precise process control applications.

2. 8-Channel Voltage & Current Outputs: Supports ±10 V voltage and 0/4–20 mA current outputs, with per-channel configuration flexibility to control drives, control valves, actuators, and other industrial devices.

3. High Accuracy & Resolution: Features 12-bit D/A converters with accuracy up to ±0.3%, ensuring stable and precise signal output for improved process control quality.

4. Fast Response Time: Typical update time as fast as 0.8 ms (for all 8 channels simultaneously), suitable for dynamic control systems requiring rapid output response.

5. Channel-to-Bus Galvanic Isolation: All output channels are electrically isolated from the backplane bus, minimizing noise interference and enhancing system stability in electrically noisy environments.

6. Advanced Diagnostics: Supports channel-level diagnostics for open-circuit, short-circuit, and overload detection. Faults are indicated by red LEDs on the module and can be monitored in STEP 7 software for fast troubleshooting.
