Model 2901A — Digital Temperature & Time Controller

Features:

• Microprocessor control

• UL approved file #: E230832

• LED display of time and temperature

• Temperature setpoint differential adjustable from 1 to 10 degrees

• All operating mode selections and parameter settings can be set from the front panel

• Multiple modes of operation for timer only or temperature and time controller

Model 2901A Digital Temperature and Time Controller features digital sensing and microprocessor-based solid-state technology for reliability and accuracy. Offering a broad 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. Depending on the mode selected, users can program for simple on/off temperature/ 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.
