Description
Replacing an output card in a legacy automation panel? The Siemens 6ES7322-1BH01-0AA0 is a SIMATIC S7-300 digital output module that expands your PLC system by adding 16 discrete channels. Operating at a nominal 24 V DC, this module acts as the physical switch interface between your S7-300 CPU and downstream field actuators like solenoid valves, motor contactors, indicators, and interposing relays.
We maintain stock of this module in factory-sealed, new condition to prevent costly process delays in your manufacturing lines.

Field Deployment Notes: Load Grouping and Thermal De-rating
Are your outputs firing simultaneously? In field deployments involving high-density transistor switching, checking the total current accumulation per bus group prevents internal trace overheating. The 16 channels on the 6ES7322-1BH01-0AA0 are split into two isolated blocks of 8 channels each. If your application switches heavy inductive loads continuously, you cannot pull 0.5 A from all 16 pins at the same time without exceeding the thermal limits of the module housing.
Well, technically it runs up to 60°C ambient, but only if you de-rate the total block current. If your cabinet ambient temperatures hover around 40°C, you can safely pull the full 4.0 A per group; push the enclosure past 60°C, and you must drop your total aggregate load per group by half to avoid triggering thermal damage.
Important Hardware Detail: When landing field wires on your matching 20-pin connector, look closely at pin 1 and pin 20. Pin 1 requires your external 24 V DC supply (+M) for the first group of eight outputs, while pin 20 serves as the common ground connection (M). Swapping these or missing the common connection on pin 10 (the ground for the second group) will cause an entire block of 8 channels to remain dead, even though the CPU status bytes show the outputs are active.
Global Trade and Shipping Logistics Guide
Moving programmable controller components through global logistics channels requires clear regulatory filing data to streamline border entries.
1. Export Compliance & Customs Tariff Profiles
The Siemens 6ES7322-1BH01-0AA0 is classified as basic industrial automation hardware, making it exempt from strict high-tech or cryptographic dual-use trade bans.
- HS Code: 85371091 (Programmable logic controllers for voltages under 1,000 V)
- ECCN: EAR99 (No export license required for non-embargoed trade routes)
2. Incoterms and Delivery Performance
We standardly execute international orders under CIP (Carriage and Insurance Paid To) or EXW (Ex Works) guidelines. For critical factory breakdown situations, we recommend opting for CIP via priority air express, ensuring the module clears regional hubs and arrives at your terminal facility within 48 to 72 hours.
3. ESD and Physical Cargo Protection
Transistor-based output modules are highly sensitive to electrostatic discharge and vibration. Every module is shipped in its original Siemens cardboard packaging, which is vacuum-sealed inside an anti-static ESD shielding wrap before being nested within a reinforced outer shipping box.
Frequently Asked Questions
- Does this module come with the 20-pin front connector included? No, it does not. Siemens sells front connectors as separate line items because wiring preferences (screw vs. spring-clamp) vary by project. You must source part number 6ES7392-1AJ00-0AA0 for the screw-terminal version or 6ES7392-1BJ00-0AA0 for the spring-clamp version.
- Can this module directly drive heavy AC contactor coils? No. The 6ES7322-1BH01-0AA0 is strictly a solid-state DC module rated for 24 V DC loads. Attempting to switch an AC voltage through these transistors will destroy the internal components instantly. For AC switching, utilize a relay output module like the 6ES7322-1HH01-0AA0.
- What should I do if the module displays an external fault LED? Check for short circuits on the field wiring side or a loss of the external 24 V DC auxiliary power supply on pins 1 or 11. The SF (System Fault) LED illuminates if the module detects that its external load voltage is missing while the backplane bus is energized.
