Anderson-Bolds specifies and stocks mechanical and digital timers and counters
Our Timer modes of operation include, on delay, off delay, interval, recycle, one shot and 7 day/24 hour timers.
Our timers styles are panel mount, plug in (1/4 Din, 72mm ), octal and 11 PIN(,48mm and 1/8 din), surface mount (2x2) and DIN rail mount
On Delay-- OPERATION: Upon application of power, the time delay begins. The output is de- energized before and during the time delay. At the end of the time delay, the output is energized (relay is transferred) and remains energized until power is removed.
RESET: Removing power resets the time delay and output.
Interval Timing-- OPERATION:Upon application of power, the time delay begins. The output is energized (relay is transferred) during the time delay. At the end of time delay the output is de-energized and remains de-energized until power is removed.
RESET: Removing power resets the time delay and the output.
Off Delay- OPERATION:Power must be applied to the input before and during timing. Upon closure of the initiate switch, the output is energized (relay is transferred). The time delay begins when the initiate switch is opened (trailing edge triggered). The output remains energized during timing. At the end of the time delay, the output is de-energized. The output will energize if the initiate switch is closed when power is applied.
RESET:Reclosing the initiate switch during timing resets the time delay. Loss of power resets the time delay and output.
Recycle Timer/Percentage Timing-- OPERATION: ( ON TIME FIRST) Upon application of power, the output is energized (relay is transferred) and the ON time begins. At the end of the ON time, the output de-energizes and the OFF time begins. At the end of the OFF time, the output is energized and the cycle repeats as long as power is applied. The OFF time may be the first delay in some recycling timers.
RESET: Removing power resets the output and time delays, and returns the sequence to the first delay.
Single Shot-- OPERATION:Power must be applied to the input before and during timing. Upon momentary or maintained closure of the initiate switch (leading edge triggered), the output is energized (relay is transferred) for a measured interval of time. At the end of the delay, the output de-energizes. Opening or reclosing the initiate switch during timing has no effect on the time delay.
RESET:Reset occurs when the time delay is complete and the initiate switch is opened. Loss of power resets the time delay and output.
Multi-Function Timers-- OPERATION: A timer having two or more of the above functions with a selector switch to chose the function required. The reset would depend on the function chosen.

SSAC -- Solid State Advanced Controls
Time Delay Relays
Time Delay Relays all include a combination of a solid state timing circuit and an electromechanical relay output. This combination provides the user with isolation between the operating and load voltages and multiple switching contacts in either SPDT or DPDT forms. Most of the relay contacts are rated 10 amps resistive @ 240 VAC. Many are in the popular octal plug-in package and require the purchase of a socket. Others surface mount with one or two screws and have male 0.25" quick connect terminals. Some are encapsulated to protect the solid state circuitry. A large selection of time delay ranges and adjustment methods are available.
All popular modes of operation are available in this group of totally solid state timing modules. They contain no moving parts so 100 million operations is typical. They are encapsulated to protect their analog or digital solid state circuitry. A large selection of time delay ranges are available, knob or switch adjustment, or external adjustment, or factory fixed time delays can be ordered.
Flashers and Tower Controls
A complete line of solid state flashers for lamp and buzzer flashing. 50/50 duty cycle, fixed or adjustable flash rates from 10 to 100 fpm. Solid state outputs rated to 30 amps, isolated DPDT relay outputs rated 10 amps resistive.
A complete selection of products for Tower Controls including beacon flashers, Obstruction Lamp Alarm Relays, Flasher and Beacon Alarm Relays and Photo Control for Tower Lighting. SSAC Tower Controls adhere to FCC specifications.
Three phase voltage monitors provide protection against: phase loss, phase reversal, low voltage, high voltage, and unbalanced voltages. Designed to protect motors and other sensitive loads from voltage faults. Continuously monitors three phase voltages, output transfers when a voltage fault is sensed.
AC Current Sensors for 0.5 to 50 amp applications. Operations include overcurrent, undercurrent, go/no go, or LED indication. Solid state outputs to 1 amp, or isolated 10 amp rated SPDT relay output. Adjustable or factory fixed trip point and trip delay.

Saia-- Saia-Burgess Timers
17.5mm DIN Rail Mount Timers
These TDR's save panel space while being convenient. Mounted on a DIN rail and only 17.5 mm in width they have alot of features in a small area. They come in on-delay, off delay, interval, repeat cycle and a Multi function model. The input voltage is also universal from 24-48vDC and 24-240 VAC. The analog set pot is adjustable with a screw driver as are the different range options.The KOL 3 Series has 6 ranges from 1 second to 10 hours and the KOL 1 Series has ranges from 15 seconds to 60 minutes.
