FEATURES
BENEFITS
Model 2901A Digital Temperature and Time Controller
features digital sensing and microprocessor-based solid-state
technology for reliability and accuracy.
temperature control range from 40ºF to 999ºF (4ºC to 530ºC),
the controller can be used for a wide variety of commercial
food equipment and industrial control applications.
Five operating modes provide the user with a great
degree of flexibility from the time only control or simultaneous
temperature and time control.
selected, users can program for simple on/off temp-
erature/time control, cook/heat and setback temperatures, or
hold and cooking/heating temperatures. All operating mode
selections and parameters are easily set from the front panel
for optimum user convenience.
The 2901A Controllers allows user selection of type “J” (±5ºF
accuracy) or “K” (±1.8ºF accuracy) thermocouple sensors
and user-selectable temperature readings in ºF or ºC.
Temperature setpoint differential is adjustable from 1 to 10
degrees. Power options include choice of Selco/ECC’s Solid
State Transformer that automatically adjusts to line inputs
from 75 to 305 VAC; 50/60Hz, or Standard Transformer input
of 115/230VAC, 50/60Hz.
The 2901A features a 0.56-inch, four-digit LED display for
easy readability of temperature and time indication and
measures 6.2” L x 2.1” W. UL approved file #: E230832.
