Description
Product Name: 705-D0D Allen Bradley Programmable controller
Product details:
The Allen-Bradley 705 Series Reversing Starter is an electro-mechanical device used for the starting and protection of AC induction motors, specifically those that need to operate in two directions (forward and reverse).
⚙️ Product Type
-
Reversing Starter Contactor
-
Series: 705
-
Function: Controls the power to a motor to allow for directional change.
📊 Typical Product Parameters (Specifications)
The exact specifications depend heavily on the specific catalog number (e.g., 705-D0D23). Common parameters include:
| Parameter | Typical Value Range |
| NEMA Size | Size 0, 1, 2, or 3 (Determines maximum HP/Current) |
| Coil Voltage (Control) | 120V AC, 240V AC, 480V AC, etc. |
| Max HP Rating | Depends on NEMA size and voltage (e.g., 3HP @ 230V, 5HP @ 460V for Size 0) |
| Max Current Rating | Varies by size (e.g., 18A, 27A, 45A) |
| Poles | 3-Pole (for three-phase motors) |
| Overload Relay | Typically equipped with a separate, adjustable Bi-metallic Overload Relay (Thermal or Solid-State) |
✅ Product Advantages
-
Motor Direction Control: Provides a single, integrated unit for safely reversing the motor’s direction, which is essential in many industrial applications.
-
Durability and Reliability: As a legacy Allen-Bradley product, it is known for robust, industrial-grade construction suitable for demanding environments.
-
Integrated Protection: Includes built-in overload protection to safeguard the motor windings from damage due to excessive current.
-
Mechanical Interlock: Features an integral mechanical interlock to prevent both the forward and reverse contactors from engaging simultaneously, which would cause a short circuit.
-
Ease of Maintenance: Designed for straightforward component replacement (coils, contacts, overloads).
⚠️ Precautions (Important Notes)
-
Proper Sizing: The starter must be sized correctly based on the motor’s horsepower (HP), full-load current (FLA), and system voltage to prevent premature failure or motor damage.
-
Overload Setting: The Overload Relay must be correctly calibrated to the motor’s nameplate Full Load Amps (FLA) to ensure proper thermal protection.
-
Wiring Safety: Only qualified personnel should perform installation and wiring. Ensure the power is completely disconnected (Lockout/Tagout) before performing any work.
-
Mechanical Interlock Check: Regularly verify that the mechanical interlock is functioning correctly to prevent simultaneous forward/reverse operation.
-
Environment: Ensure the starter is installed in an enclosure that provides appropriate protection against dust, moisture, and corrosive elements, matching the environment’s NEMA/IP rating.
🏭 Product Applications
The Reversing Starter is critical in applications where a motor needs to perform work in two opposite directions:
-
Conveyors: Reversing the direction of material flow.
-
Cranes and Hoists: Lifting/lowering and lateral movement.
-
Machine Tools: Controlling spindle rotation for different operations.
-
Packaging Machinery: Controlling movement in automated systems.
-
Gate and Door Operators: Opening and closing large industrial doors or gates.
