Digital temperature controller TLB29

with LCD displayprogrammableprocess

Controller for refrigerating units, 2 inputs and 3 outputs It’s a controller that can be used for refrigeration applications equipped with ON/OFF temperature control and defrost control at time intervals through electric heating or hot gas/reverse cycle. The 3 outputs can be used to control the defrost compressor, evaporator fans, an auxiliary device (light, second compressor, etc.) or an alarm. The 2 inputs for PTC or NTC temperature probes can be used to measure the cell temperature and to measure the evaporator temperature, while the digital inputs can be programmed to perform various functions such as defrost commands, the selection of 2 or 4 different memorized Set Points, the signaling of an external alarm, the activation of a continuous cycle, the activation of the auxiliary output etc. Furthermore, the instrument is equipped with a voltage alarm which deactivates the outputs if the mains voltage is too high or too low and can be equipped with an internal buzzer for signaling alarms. The programming of the operating parameters takes place through a remote keyboard (TLBTA) in the standard version, or through 4 capacitive keys (S-touch) in the version with integrated keyboard.
