Artisan - 4950PM 7 Day Controller

Description

The 4950PM provides 7 day programming of two high power set of contacts that are programmable ON and OFF over a 24 hour period. All programming, verification, and operation is performed from the front panel using the 12 switches of the keypad. The 4950PM maintains accurate time of day even after power has been removed for up to 5 days. This assures that during a power failure, the time of day is maintained and upon restoration of power the timer will automatically come on at the correct time and not require resetting of the time-of-day clock.

Specifications

Operating Voltage	12VDC ą10%, 24VAC ą10% 50/60 Hz., 115V/230V AC ą15% 50/60 Hz. (The 115V/230V model is operating voltage switch selectable)
Operating Power	7.2 watts maximum.
Timing Mode	7 day - 24 hour programmable On - OFF.
Timing Accuracy	Time-Of-Day to ą2 minutes per month.
Programmable Outputs	Two (2) SPST-NO contacts. Contacts Close at the scheduled event ON time, open at the scheduled event OFF time
Programmable Events Per Output	Eight (8) events per day. A schedule to turn one relay ON = 1 event, to turn it OFF = 1 event, with a maximum of 56 events per week. Two relays scheduled either ON or OFF at the same time is = 1 event.
Timing Tolerance	Based on the scheduled and displayed time-of-day.
Repeatability Of Event Timing	Based on the scheduled and displayed time-of-day.
Output Rating	UL/CSA rated for 1 HP, 20A 250V AC, 1.5 HP, 20A 125V AC. 1000V rms breakdown voltage between open contacts, 1500V rms breakdown voltage between all contacts and operating voltage terminals. Insulation resistance 1000MŊ at 500V DC. Mechanical Life Expectancy 10⁶ operations, Electrical Life Expectancy resistive load 10⁵ operations at 20A 250V AC, 1.5 x 103 operations inductive load (cos = 0.7) steady 20A 250V AC inrush 80A.
Digital Display	Four (4) digit red LED, 0.5 inch high characters displays, time-of-day, day-of-week, and all event schedules.
Time-Of-Day	Displayed and set in 24 hour format. 6PM = 18:00, 11:00PM = 23:00 etc.. Time-Of-Day is maintained in a smart timepiece circuit that will keep the time running for up to 5 days during a power failure. No batteries required, or embedded.
Program Memory	EEPROM type maintains the programmed schedules for up to 10 years without battery backup.
Front Panel Switches	Tactile type keypad, 0 - 9, *, and #.
Transient Protection	Protected by silicon transient suppressors which respond to transients within 1 x 10-12 seconds to a peak pulse power dissipation of 1500 watts, with transient surge currents to 200 amperes for durations up to 1/120 second at 25 deg C. Maximum transient voltage protection is 6000 volts as delivered through a source resistance of 30 ohms with a maximum duration of 8.3 milliseconds.
