The Littelfuse TDR Series of time-delay relays are comprised of digital circuitry and an isolated, 10A relay output. The on and off delays are selected by means of two, ten position binary switches, which allow the setting of the desired delay to be precise every time.

Operation (Recycling - ON Time First)
Upon application of input voltage, the green LED glows, the output relay is energized, the red LED glows, and the T1 ON time begins. At the end of the ON time, the output deenergizes, the red LED turns OFF and the T2, OFF time begins. At the end of the OFF time, the output relay energizes and the cycle repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time delays, and returns the sequence to the first delay.

Operation (Recycling - OFF Time First)
Upon application of input voltage, the green LED glows, the T1 OFF time begins, the load is OFF. At the end of the OFF time, the T2 ON time begins, the load energizes, and the red LED glows. At the end of the ON time the load de-energizes and the red LED turns OFF. The cycle repeats until input voltage is removed.
Reset: Removing input voltage resets the output and the sequence to the OFF time.

SSAC Flasher FS152

Littelfuse FS152 Flasher from ANDERSON-BOLDS

The Littelfuse Flasher 152 runs on 120 volts and has 90 Flashes per Minute (FPM) rate.

The FS100 Series (medium power) may be used to control inductive, incandescent, or resistive loads. Input voltages of 24, 120, or 230VAC are available. Fixed flash rates in stock range from 30, 50, 60, and 90 FPM, with custom flash rates ranging from 10 to 300 FPM. Encapsulation provides protection against shock, vibration, and humidity. This group of solid-state flashers has proven reliability with years of use throughout the world.
Operation
Upon application of input voltage, the T2 OFF time begins. At the end of the OFF time, the T1 ON time begins and the load energizes. At the end of T1, T2 begins and the load de-energizes. This cycle repeats until input voltage is removed.

ATC 422AR Flip Flop Timer

Anderson-Bolds Stocks the ATC 422AR Flip-Flop / Recycle Timer


Automatic Timing and Controls 422AR100S0X is a recycling Flip-Flop Timer that has on and off times.
The Series 422AR replaces the original 342 Flip Timer and the 422A flip/flop timer. All the ATC timers were capable of different on and off times making them a flip flop timer and not just a recycle timer which tends to have identical on and off times. The ATC 422AR TDR has ranges in seconds, minutes and hours and in each of these ranges you can select 1 second or 10 second, 1 minute or 10 minutes or 1 hour or 10 hours making 6 total ranges. The ON time can be in minutes while the OFF time in seconds, or the ON time in seconds and the OFF time in hours.

The 422AR is a 1/16 DiN timer with a 10 amp relay and plugs into an industry standard octal plug.  So changing an older 422A series to the newer 422AR100SOX timer is as simple and plugging the new one into the old one's socket.

ATC 422AR TDR with Octal Socket

Note that the 422AR is an analog set timer, not digital and it would be difficult to set both the on and off times to exactly the same value (it would be close though).

Use p/n 8258500 for surface/DIN rail socket for the 422AR timer.



The older part numbers that the 422AR100S0X replaces are below.
