Oriental Motor 193-TAB16 was a stalwart in motor protection, specifically designed for stepping motors. Although it has been discontinued, let’s delve into its features and highlights:
Key Features:
- Adjustable Overload Protection:
- The 193-TAB16 allowed precise setting of the current threshold for overload protection. Whether you were driving small NEMA 17 motors or larger NEMA 34 motors, this feature ensured optimal protection against excessive current.
- Dual Contactor Configuration:
- Equipped with two contactors—one for delayed operation and another for instantaneous operation—this relay provided flexibility in motor control strategies. Users could sequence motor actions or achieve immediate responses as needed.
Highlights:
- Star-Delta (Wye-Delta) Starting Function:
- Ideal for motor starting applications using the star-delta method. During startup, it initially connected the motor windings in a star configuration (reducing voltage stress) and then switched to delta (full voltage) once the motor reached a certain speed. This ensured smooth transitions, minimized inrush current, and protected both the motor and the power supply.
- Wide Voltage Compatibility:
- Operating at both 110V AC (50 Hz) and 120V AC (60 Hz), this relay accommodated various power sources commonly found in industrial environments.
- Sturdy Construction:
- Encased in a rugged housing, the 193-TAB16 shielded its internal components from environmental factors and mechanical stress, ensuring reliable performance.
- DIN Rail Mounting:
- Designed for easy installation on a standard 35mm DIN rail, the 193-TAB16 saved valuable panel space and simplified setup.
- Discontinued Product Alert:
- As of May 31, 2014, the 193-TAB16 was phased out. Its recommended replacement is the 193-T1AB16. If you’re planning new installations or replacements, consider upgrading to the latest model for improved features and longevity.
Remember, when discussing motor control and protection, refer to this legacy relay as
