Description
Product Name: 440T-MDCLE10FEFF Allen Bradley Power module
Product details:
The Allen-Bradley 440T-MDCLE10DADB is a component of the 440T Access/Chains Trapped Key Interlock Switches family. It is a Trapped Key Interlock that uses mechanical locking to manage access to dangerous machinery.
- Type: Dual Access/Chain Lock with Lever (based on a similar part number structure, the “DA” and “LE” often indicate Dual Access and Lever actuation).
- Function: It is designed to trap a “Primary Key” until a safety condition (like isolation of power) is met. Once the key is released, it can be used to unlock an access point (e.g., a guard or chain barrier). This enforces a strict sequence of operations to ensure safety.
- Key Condition: The structure of the part number suggests a condition where the Primary Key is Trapped, and the Secondary Key is Free to release a chain or lever.
- Construction: High-durability design, often featuring 316L Stainless Steel construction for robustness and corrosion resistance.
Product Parameters (产品参数)
Specific parameters for the exact part number (440T-MDCLE10DADB) are often found in the product’s data sheet, but typical specifications for this series include:
| Parameter | Value (Typical for 440T Dual Access/Chain Lock) |
| Material | Faceplate: 316L Stainless Steel |
| Type of Switch | Mechanical Locking, Dual Access/Chain Lock with Lever |
| Mechanical Life Operations | Up to 200,000 operations |
| Torque to Key | Approx. $14 text{ N}cdottext{m}$ (Newton-meters) |
| Shear Force to Key | Approx. $15.1 text{ kN}$ (kiloNewtons) |
| Operating Temperature | Typically down to $-40^circtext{C}$ |
| Relative Humidity | Up to $95%$ (non-condensing) |
| Dimensions (W x H x D) | Typical dimensions are approximately $48.5 text{ mm} times 119 text{ mm} times 27.4 text{ mm}$ |
| Misalignment Tolerance | Typically $pm 10 text{ mm}$ (for the actuator/chain mechanism) |
| Key Codes | Features unique, coded barrel assemblies (e.g., Code D/A, D/B) to prevent defeat. |
Product Advantages (产品优势)
- High Level of Safety: Enforces a rigid, sequential procedure for isolating power and gaining access, virtually eliminating the possibility of unauthorized or premature access to a hazardous area.
- Robust Construction: The use of 316L Stainless Steel provides excellent durability, corrosion resistance, and makes it suitable for harsh industrial or washdown environments.
- Tamper-Resistant: Designed with features like tamper-resistant screws and coded keys to minimize attempts to bypass the safety system.
- Long Mechanical Life: High mechanical life rating (200,000 operations) ensures reliable performance and reduced maintenance over time.
- Direct Drive Operation: Offers positive opening of contacts in switches (if an electrical variant), enhancing safety performance.
- Replaceable Code Barrel: Allows for easy replacement of the key barrel assembly if the key is lost or if the key code needs to be changed.
Precautions (注意事项)
- Proper Installation: Must be installed strictly according to the manufacturer’s instructions and relevant local safety standards (e.g., ISO 14119). Incorrect installation can defeat the safety function.
- Key Management: A rigorous system must be in place to control the distribution and storage of the unique coded keys to maintain the integrity of the interlock system.
- Regular Inspection: Periodic checks are required to ensure the interlock mechanism is free of damage, operates smoothly, and that the key is not worn.
- Misalignment: Although it has a tolerance, ensure the chain/lever mechanism is properly aligned to prevent excessive force on the key barrel, which could lead to premature wear or failure.
- Environmental Limits: Do not exceed the specified operating temperature and humidity limits.
Product Applications (产品应用)
The 440T Trapped Key Interlock is primarily used for Access Control and Isolation for Safety in industrial environments.
- Machine Guarding: Securing access gates or doors to dangerous machinery (e.g., robotic cells, mixers, high-speed equipment, large presses) to ensure power is isolated before entry.
- Sequential Safety: Used in systems where a sequence of actions is critical for safety, such as ensuring power is off before a guard is opened, and the guard is closed before power can be re-energized.
- Isolation Points: Used on main electrical disconnects or valves where a key must be trapped to keep the power/fluid isolated until the key is needed to open a protective barrier.
- Harsh Environments: The robust 316L stainless steel construction makes it ideal for use in food and beverage, pharmaceutical, chemical, and outdoor applications where high hygiene standards or resistance to corrosion is required.
