- 34. RELAY
- 35. RELAY Electromechanical relays perform many functions. Some include: • Isolation of control circuits from load circuits, or AC powered circuits from DC powered circuits. • Switching multiple currents or voltages to different loads using one control signal. • Monitoring industrial safety systems and disconnecting power to machinery if safety is compromised. • Using several to provide simple logic functions such as 'AND,' 'NOT,' or 'OR' for sequential control or safety interlocks.
- 37. BASIC OPERATION 1. Power is applied to the coil inducing a magnetic field. 2. The magnetic field is converted into a mechanical force by attracting the armature. 3. The moving armature closes/opens one or more electrical contacts 4. The contacts allow switching of power to the load such as a motor, lamp, etc 5. Once coil voltage is removed, the magnetic field collapses, the contacts separate, and return to their "normal" position.
- 38. RELAY CONTACT OPERATION The Operate time is the time between energizing the coil and first contact closure, not including contact bounce. The Release time is time it takes the contacts to open after power has been removed from the relay coil.
- 42. RELAY Relay A will work with DC or AC and proper polarity of the wiring is not required for relay operation.
- 43. RELAY Relay B includes a surge absorbing diode across the relay coil to absorb the back electromotive force when the coil is de-energized. Care must be taken when connecting this type of relay to maintain proper polarity.
- 44. RELAY Relay C uses a permanent magnet to assist the electromagnetic force. The pole of the coil at the working gap is either North or South depending on the polarity of the coil.
- 45. Latching vs. Non-Latching Relays can be Latching (Bistable) or Non-Latching (Monostable). Non-Latching Relay Latching Relay
- 46. AC DRIVE Motor Induksi (Alternating Current/AC) RPM MPH An AC Drive is a device used to control the rotational speed of an AC (alternating current) motor by controlling the frequency of the electrical power supplied to the motor.

- 48. AC DRIVE COMPONENTS Rectifier/Penyearah (AC to DC) Capacitor (Power Store) IGBT (Transistor) PWM (DC to AC)
- 49. Volts per Hertz Drives
- 50. Sensorless Vector Drives • PWM Mode (Pulse Width Modulation) • High starting torque at low speeds (200% at 0.5Hz) • Speed regulation is improved to <1% error • Speed and torque reference inputs • Self-tuning & Torque control without feedback • Can be used with permanent magnet motors, and high speed motors up to 1000 Hz • Low dynamic performance on sudden changing loads • Lack the ability to hold a motor at zero speed
- 51. Vector Drives with Feedback Device • This drive is currently the only type of AC Drive available with similar or equivalent performance to DC Drives. • These drives monitor the voltage and current outputs, as well as encoder feedback from the motor for closed loop Vector control. • This feedback is used to adjust the output waveform to achieve the tightest speed control.
