7 Day- 24 Hour
Programmable Timer
The model 4950PC is a re-designed version of the
standard Artisan Controls Corporation's model 4950
intended for embedded applications. The 4950PC
provides 7 day programming of two SPDT sets of
contacts programmable for ON and OFF control over a
24 hour period. All programming, verification, and
operation is performed from the front using the 12
keypad switches. The 4950PC provides a large .5 inch
LED display and maintains accurate time of day even
after power has been removed for up to 10 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. Schedule program is held in EEPROM non-volatile memory.

Hz. (The 115V/230V model is operating voltage switch selectable)
7.2 watts maximum. On-Board Fuse provided on AC models.
7 day - 24 hour programmable ON - OFF.
Time-Of-Day to ±2 minutes per month.
Two (2) SPDT contacts. Contacts energize at the scheduled event ON
time, De-energize at the scheduled event OFF time
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.
Based on the scheduled and displayed time-of-day.
Based on the scheduled and displayed time-of-day.
Rated for 20A resistive (NO), 10A resistive (NC) at 250V AC. 1000V
rms breakdown voltage between open contacts, 1500V rms breakdown
voltage between all contacts and operating voltage terminals. Insulation
resistance 1000M at 500V DC. Mechanical Life Expectancy: 106
operations min., Electrical Life Expectancy: resistive load 105 operations
at rated load. Contact factory for additional ratings.
Four (4) digit red LED, 0.5 inch high characters displays, time-of-day,
day-of-week, and all event schedules.
Displayed and set in 24 hour format. 6:00PM = 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 10 days during a power failure. No
batteries required, or embedded.
EEPROM type maintains the programmed schedules for up to 10 years
without battery backup.
Tactile switches, 0 - 9, *, and #.
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°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.
0°C to +70°C.
Five (5) 3/8 mounting spacers can accommodate #6 mounting screws.
9 terminals accommodate wire sizes from 16 AWG - 22 AWG.
A comprehensive handbook is supplied with each model. The handbook
provides all instructions, with examples, necessary to operate and
program the model 4950PC.
