Description

Autonics W48×H48 mm Star-Delta Analog Timers - AT8SDN

Relay, Power ON Start, 8-pin plug, Time setting

Autonics AT8SDN timer is an 8-pin socket type timer with an analog type dial for easy adjustments.

Universal power supply of 100-240 VAC ~, 24-240 VDC timer allows for flexibility in product use. A power on and output status LED easily verifies proper mode function.

This Timer provides:

  • Time setting operation method
  • STAR-DELTA output operation
  • POWER ON START time operation
  • 8-pin plug Terminal
  • 100-240 VAC ~, 24-240 VDC power supply
  • STAR contact: SPST (1a): 1, DELTA contact: SPST (1a): 1 Control output
  • Setting range: 0.5 to 5 sec, 1 to 10 sec, 5 to 50 sec, 10 to 100 sec
  • Easy to check output status by LED display
  • Simple setting time, switching time operation

Output Operation

The operating mode determines the output method that is used when the set time has reached. The AT8SDN has one output operating modes available:

  • STAR-DELTA: Star delta timer is an electronic timer which counts the time of its coil energize and trip the circuit when the time exceed presetting time. The timer is doing normal NO and NC operation.

Time operation

Time operation of AT8SDN is "POWER ON START" type. That means the time clocking starts when voltage is applied to the timer power supply section. This kind of timers are most often used for automated machines.

Setting range

The AT8SDN has 4 types of time ranges: 0.5 to 5 sec, 1 to 10 sec, 5 to 50 sec, 10 to 100 sec.

Terminal

The terminal of this product is an 8-pin plug.

Control output

The AT8SDN has "relay" control output. it has 1 contacts which is STAR contact: SPST (1a): 1, DELTA contact: SPST (1a): 1 depending on output operation mode.

Error

Different types of errors are specified for AT8SDN timer:

  • Repeat: ≤ ± 0.2% ± 10 ms
  • Voltage: ≤ ± 0.5%
  • Temp: ≤ ± 2%
  • Y setting time: ≤ ± 5% ± 50 ms
  • Y -∆switching time: ≤ ± 25%

Temperature

There are limitations in temperature and humidity in which AT8SDN timer is used:

  • Ambient temperature: -10 … 55°C
  • Ambient humidity: 35 to 85%RH
  • Storage temperature: -25 … 65°C

Environment resistance is rated at no freezing or condensation.

 Application / industrial

  • Starting large capacity motor.
