Autonics W38×H42 mm Twin Analog Timers - ATS8W-21

Relay, Power ON Start, Various output operatio, FLICKER output

Autonics ATS8W-21 timer is an 8-pin socket type timer with an analog type dial for easy adjustments.

Universal power supply of 24 VAC ~ 50/60 Hz, 24 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
  • FLICKER output operation
  • POWER ON START time operation
  • 8-pin plug Terminal
  • 24 VAC ~ 50/60 Hz, 24 VDC power supply
  • Time-limit SPDT (1c): 2 or Instantaneous SPDT (1c): 1 + Time-limit SPDT Control output (1c): 1 depending on output operation mode
  • Setting range: 0.1 to 1 sec, 1 to 10 sec, 0.1 to 1 min, 1 to 10 min, 0.1 to 1 hour, 1 to 10 hour
  • Various output operations (6 operation modes)
  • Twin timer to set ON/OFF time individually
  • Easy installation/maintenance with the dedicated bracket for DIN 48 × 48 mm
  • Close and DIN rail mounting with the dedicated socket (PS-M8) width 41 mm (ATS8W)

Output Operation

The operating mode determines the output method that is used when the set time has reached. The ATS8W-21 has one output operating modes available:

  • FLICKER operation: With flicker operation, an output repeatedly turns ON and OFF at the set time after an input is received.

Time operation

Time operation of ATS8W-21 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 ATS8W-21 has 6 types of time ranges: 0.1 to 1 sec, 1 to 10 sec, 0.1 to 1 min, 1 to 10 min, 0.1 to 1 hour, 1 to 10 hour.


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

Control output

The ATS8W-21 has "relay" control output. it has 2 contacts which is Time-limit SPDT (1c): 2 or Instantaneous SPDT (1c): 1 + Time-limit SPDT (1c): 1 depending on output operation mode depending on output operation mode.


Different types of errors are specified for ATS8W-21 timer:

  • Repeat: ≤ ± 0.2% ± 10 ms
  • SET: ≤ ± 5% ± 50 ms
  • Voltage: ≤ ± 0.5%
  • Temp.: ≤ ± 2%


There are limitations in temperature and humidity in which ATS8W-21 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.
