Process Timer/Controller
The PTC41 multipurpose panel
meter functions as a clock/timer
controller or stopwatch. The unit
features 8 different time bases along
with a built-in date function. Five
controller output modes enable the
user to program the unit for virtually
any timer control application.
The PTC41 is perfectly suited for life
cycle testing, turning 4 loads on and
off based on timing cycle. The clock
time base is derived from the 50 or
60 Hz power line and from the
internal crystal oscillator.
Front-panel pushbuttons allow
configuration and access to the
meter’s many features. These
features can also be accessed
through RS232 or RS485 serial
communications. The front panel
displays values and messages with
six 14-segment LEDs.
