HG-KN73J-S100 MITSUBISHI Output Module

Product  Description：

Mitsubishi Electric Output Modules are critical hardware components of the MELSEC PLC series designed to convert the digital logic processed by the CPU into physical electrical signals. These signals are used to command a vast array of external field devices, effectively allowing the controller to "act" upon the environment. By providing various switching technologies, Mitsubishi ensures that these modules can safely and efficiently handle everything from low-power status lamps to high-power contactors and solenoids.

Product Parameters

The technical profile of an output module depends heavily on its switching technology (Relay, Transistor, or Triac), but standard parameters include:

• Output Points: High-density options ranging from 8, 16, 32, to 64 points per module.

• Switching Types: Relay (for AC/DC universal switching), Transistor Sink/Source (for high-speed DC switching), and Triac (for AC-specific loads).

• Rated Load Voltage: Standard ratings include 12V-24V DC for transistors and up to 240V AC for relay and triac versions.

• Current Capacity: Typically ranges from 0.1A per point for high-density transistor modules to 2A per point for robust relay modules.

• Response Time: Transistor modules offer ultra-fast switching (under 1ms), while relay modules typically respond within 10ms to 12ms.

• Surge Protection: Built-in suppression such as Zener diodes for transistor modules or varistors for triac modules to handle inductive kickback.

Product Advantages

Mitsubishi Output Modules are engineered for durability and precision control in industrial settings:

• Flexible Load Handling: The availability of multiple output types allows engineers to choose the most efficient switching method for their specific load, whether it requires high frequency or high current.

• Optical Isolation: Photocouplers are used to provide a physical barrier between the sensitive internal PLC logic and the external field wiring, protecting the CPU from electrical faults.

• Diagnostic Feedback: Integrated LED arrays provide real-time status for every output point, allowing for rapid visual verification of the controller's operation.

• Advanced Safety Features: Many modules feature short-circuit protection and thermal shutdown capabilities to prevent hardware failure during accidental wiring faults.

• Compact Design: Through the use of high-integration components, Mitsubishi provides high-density modules that allow for smaller control panels and reduced wiring costs.

Product Applications

These modules are the primary interface for driving action across various industries:

• Motor Control: Activating contactors and starters to manage the operation of fans, pumps, and conveyors.

• Pneumatic Systems: Driving solenoid valves to control the movement of air cylinders in automated assembly lines.

• Visual and Audible Alarms: Triggering stack lights, sirens, and HMI indicators to signal machine status or emergency conditions.

• Heating Elements: Using triac or relay outputs to manage heaters in plastic injection molding machines or industrial ovens.

• Synchronization: Sending trigger signals to third-party equipment like industrial inkjet printers or vision inspection cameras.

Important Precautions

To prevent damage to the module and ensure system safety, the following guidelines must be followed:

• Inductive Load Protection: When driving inductive loads (coils, solenoids, or relays), always use external suppression devices like diodes (for DC) or RC snubbers (for AC) to protect the module's internal switching elements from back-EMF.

• Common Terminal Current: Be mindful of the "per common" current limit. While an individual point may handle 0.5A, the common terminal (which shares the return path for 8 or 16 points) has a total maximum rating that must not be exceeded.

• Fuse Selection: It is highly recommended to install external fuses on the output lines to protect the module from short circuits in the field wiring, especially for relay-type modules.

• Switching Frequency: Avoid high-frequency switching on relay modules. Relays have a finite mechanical life (number of operations); for high-speed or frequent pulsing, transistor modules should always be used.

• Correct Polarity: For transistor output modules, ensure the external power supply is connected with the correct polarity (Sink vs. Source). Incorrect wiring can result in the module being unable to turn off or permanent component failure.
