6ES7322-1HH01-0AA0 Siemens S7-300 SM322 16x Relay Output Module

6ES7322-1HH01-0AA0 — Siemens SIMATIC S7-300 SM322 16x Relay Output Module (Industrial-Grade, Original New)

The 6ES7322-1HH01-0AA0 is a 16-channel potential-free relay output module manufactured by Siemens for the SIMATIC S7-300 PLC System. As a core component of the SM 322 Digital Output family, this Control Module delivers robust, high-current switching of both AC and DC loads up to 230 V / 5 A per channel — making it one of the most widely deployed relay output cards in Industrial Automation worldwide. Every unit we supply is 100% Brand New and Factory Sealed, sourced directly from authorized Siemens distribution channels to guarantee authenticity and full performance compliance.

Procurement teams and maintenance engineers across Oil & Gas, Power Plants, and heavy manufacturing consistently specify the 6ES7322-1HH01-0AA0 when they need a proven, drop-in replacement for aging S7-300 racks or emergency stock replenishment. Its potential-free dry contacts eliminate polarity concerns, while per-channel LED diagnostics and group fault indicators dramatically reduce mean-time-to-repair in critical PLC System environments. Whether you are managing a planned upgrade or responding to an unplanned shutdown, this Original New Spare Parts solution ships fast to keep your line running.

With over 3.5 million units in global service and full compatibility with TIA Portal 18 and STEP 7, this module remains the benchmark for reliable relay output in the S7-300 platform. Contact our team today for a competitive quote and same-day shipping confirmation.

Typical Application Scenarios

From the perspective of a Senior Engineer who has commissioned S7-300 systems across multiple industries, the 6ES7322-1HH01-0AA0 addresses specific pain points that generic relay cards simply cannot resolve:

• Oil & Gas Refineries: Controls 230 VAC valve actuators and motor starters in hazardous-area panels where potential-free contacts are a safety requirement. Replaces failed relay cards without rack reconfiguration.
• Power Plants & Utilities: Drives protection relay coils and annunciator panels in substation automation. The 5 A continuous rating handles inductive loads without derating.
• Automotive Manufacturing: Manages conveyor interlocks and pneumatic valve banks on body-in-white lines. Hot-swap capability minimizes production downtime to under 20 minutes.
• Building Automation & HVAC: Integrated into Siemens Desigo systems for lighting control, damper actuation, and chiller sequencing — leveraging existing S7-300 infrastructure.
• Marine & Offshore: Deployed on cruise ships and offshore platforms for safety-critical door control and pump relay applications where vibration resistance and long relay lifetime are mandatory.

Core Features & Technical Advantages

• 16 Potential-Free Relay Contacts — Arranged in 4 groups of 4; true dry contacts eliminate voltage drop and polarity issues across mixed AC/DC load panels.
• Heavy-Duty 5 A / 230 V AC Rating — Handles resistive and inductive loads with a peak capacity of 8 A, covering the vast majority of industrial actuator and motor-starter applications.
• Precision Per-Channel LED Diagnostics — Instant visual fault identification at the module face, with group fault LEDs readable from the aisle without opening the cabinet.
• Robust Mechanical Relay Lifetime — — 10 million mechanical operations and 100,000 electrical operations at full 5 A load, engineered for continuous 24/7 industrial duty cycles.
• Seamless TIA Portal 18 & STEP 7 Integration — Zero-configuration hardware catalog recognition; direct replacement for 6ES7322-1HH00-0AA0 and all earlier revisions without software changes.
• Compact 40 mm Rack Footprint — Single-slot installation in any S7-300 rack position; 4.5 W typical power loss minimizes thermal load on the backplane.

Technical Specifications & Selection Guide

Selection Tip: If your application requires switching loads above 230 V AC or more than 16 channels per slot, consider the SM 322 6ES7322-1BL00-0AA0 (32x DC 24V) or consult our engineers for a custom rack configuration.
