Manufacturer warranty Description
ATC, 314B-134-Q-2-C, 314B Series, Plug-In Multi-Range Off Delay / Interval TDR (1 Sec,10 Sec,100 Sec), 120 VAC, 50/60 Hz, OFF-Delay Model
Features:
- Dial selected adjustable ranges: 0.035 - 1.0 Sec, 0.18 - 10 Sec., 1.8 - 100 Sec
- Dust, moisture and impact-resistant molded plastic case
- 120 VAC, 50/60 Hz
- OFF-Delay Model
The ATC 314B is an economical multi-range solid-state TDR with two models; one for OFF-Delay (delay-on-break) and one for interval-ON-Delay operation. With three dial-selected adjustable ranges, it provides any timing period between 0.035 and 100 Sec with excellent repeat accuracy even with wide changes in voltage, temperature and reset time.
OFF-Delay
Presuming the AC line is energizing the unit continuously, when the start switch is closed the relay energizes, the pilot light goes on and the unit resets. Opening the start switch begins the timing cycle. A relaxation oscillator runs at a rate determined by the set pot. When the oscillator count is equal to the level set by the range switch, a digital count circuit is satisfied and the unit times out. At time out, the timing circuit and relay are de-energized and the pilot light goes off. Closing the start switch resets the unit. After a power failure (or on first startup) the unit will go to the timed out condition (relay de-energized) until the unit is reset by closing the start switch to begin a new cycle. Through advanced circuit design and packaging technology, the ONDelay ATC 313 packs all of the performance of a conventional plug-in TDR in a space-saving housing. It features a digital timing circuit which ensures high repeat accuracy and excellent noise immunity.

- Rating 240V 1/10 HP at 120V
- Models OFF-Delay
- Type DPDT, hard wired
- Housing Dust, moisture and impact-resistant molded plastic case
- Power Requirements 120 VAC 95 to 132V, 50/60 Hz, 0.02A
- Reset Time 75 mSEC during timing or after time-out
- Contact 7A resistive at 120
- Temperature Rating 32 to 158° F (0 to 70° C)
- Repeat Accuracy ± 1% of setting or 2.0 mSEC, when temperature is constant and line voltage is constant or varies within limits ± 4% of setting or 2.0 mSEC, when line voltage is constant and temperature varies within limits ± 6% of setting or 2.0 mSEC, when line voltage and temperature vary within limits
- Setting Accuracy 10% at full scale
- 4 Ranges(And Minimum Settings) 0.035 – 1.0 Sec 0.18 – 10 Sec 1.8 – 100 Sec
- Life 50,000,000 operation (no load)
- Power Interruption A power failure over 5 mSEC during timing will cause relay drop-out. If power is restored in up to 75 mSEC, the unit will re-energize its relay and continue timing. If the power loss is over 75 mSEC the unit will lock in to the timed-out (relay de-energized) position until reset
