Timer, ChronTrol

Description

Prism Research Glass is proud to offer the ChronTrol Timer. Because of their compact size and portability, the XT Table Top Timers are especially productive in scientific laboratories and other environments where quick and easy access to the keyboard and outputs is desirable.

ChronTrol Table Top timers give you push button control of up to four independent circuits which can operate electrical devices such as lights, valves, solenoids, pumps, motors, fans or other equipment.

With 20 independent On/Off programs – or up to 40 programs optional – you can exercise control right to the second, am and pm, every day of the week. Use the keyboard to enter the time settings which display on the digital clock during entry.

Any or all of the available programs can apply to an individual output, so the On/Off sequencing is as simple or as complex as you require.

• Twenty programs (optionally 40)
• 2 or 4 independent circuits, AC receptacles
• Up to 8 inputs for external activation
• Cycle times from 2 seconds to 1 year
• Separate On and Off time settings and Cycle times on each
program
• 6-digit display shows hours, minutes, and seconds
• Directly replaces multiple mechanical timers

• Tamper-resistant locking keyboard
• Program up to one year in advance
• Weekly cycle with day omission
• 9-volt battery backup keeps time 14 days during power outage
• Battery backup keeps time even during power outages
• 12- or 24-hour time readout with Countdown timer
• Easy to set and operate
• Serial interface for remote monitoring

20 ON/OFF PROGRAMS (40 OPTIONAL)

Assign up to 20 independent programs.  Each program with independent On and Off times, in any combination to the (up to four) individual circuits. Make settings to the second from the keyboard, with AM/PM selection. Each program has individual cycle length and day-of-the-week omission settings.

CYCLE LENGTH

Set any program to repeat, or cycle, anywhere from once every 2 seconds to once a year. Use this feature to simulate photoperiodic variation to adjust for daily changes in the times of sunrise and sunset. Also use for short interval repetitive operations.

DAY OMISSION

Selectively omit programmed operations on any day or days of the week, including holidays.

CALENDAR OPERATIONS

You can program ChronTrol’s versatile calendar compensating for leap years and any number of holidays. Set On/Off programs for specific dates.

DAYLIGHT SAVING TIME

ChronTrol’s real-time clock moves forward or backward one hour at Daylight Saving Time, automatically.

COUNTDOWN TIMER

ChronTrol Timer display can show time remaining until the occurrence of any of its programmed events. It will display inn hours, minutes and seconds.

EASY VERIFICATION

• An audible tone acknowledges any Audible Keyboard Entry Entries made through the front panel keyboard.
• Assign Next Program Program numbers in any order, or ChronTrol will choose the next available program automatically.
• Cross-Review feature allows the user to find out immediately what program or programs control any given circuit.

MANUAL OVERRIDE

Switch any circuit On or Off immediately without waiting for or disturbing programmed operations.

POWER FAIL PROTECTION

The time of day continues to operate, with crystal accuracy, during power failure. A nine-volt battery keeps the clock operating and protects the system memory to prevent the loss of stored programs. When power returns, all occurrences of On and Off events are accounted for. Outputs are switched to the proper positions for the current time, in sequence or all at once.

INPUTS

ChronTrol Timer equipped with inputs can perform timing sequences that are synchronized or triggered by contact closures, and they can switch circuits On and Off based on external conditions. As many as 8 inputs can be wired to detectors, push buttons, or automatic equipment through a convenient rear panel connector.

USE AS AN INTERVAL TIMER

Set up to 40 independent timing operations at once. Set durations in hours, minutes and, if desired, seconds, from one second through one year. Timing intervals can be triggered and re-triggered through the keyboard, or by any of the 8 available inputs, or by other operational programs. Timing intervals can be set to repeat at any rate from two seconds (one second on, one second off) to one year.

SERIAL COMMUNICATIONS

Access and perform all programming information and procedures via computer terminal through ChronTrol’s RS-232 serial communication port. Or, by attaching a modem to this port, program remotely over the telephone to facilitate centralized control.
