DIGITAL INDICATOR AND CONTROLLER FOR HEATING OR REFRIGERATION WITH NATURAL DEFROST THROUGH COMPRESSOR SHUTDOWN AND INTERNAL DATALOGGER

Designed for cooling or heating application. MT-512EL Log is equipped with 1 powerful 2HPrelay, 1 temperature sensor, 1 digital input, data logger, cyclic time for natural defrost, IP65 frontal, min-max temperature record, sensor response time control, fast freezing mode, tamper-proof function, control functions shutdown and RS485 serial communication port for Sitrad real-time monitoring and management.

It features a single relay output, for cooling or heating purposes, combined to a cyclical timer for natural defrost. The natural defrost can be forced or performed through an off refrigeration cycle. It also features a configurable digital filter, which has the aim of simulating an increase of mass in the environment sensor, thus increasing its response time, that is, the sensor response becomes slower. In addition to those features, the MT-512EL Log has tamper-proof function that blocks the keypad preventing unauthorized users changing its settings, and a control function shutdown that deactivates the controlling outputs turning the instrument into a digital temperature indicator. Have an open-door indication and an internal memory for data storage (datalogger), which allows for recording the measured temperature and the control output status at user-determined intervals.

This product is CE, UL and NSF certified. According to UL laboratory tests, this product is also suitable for installations with R290 and R600a gases.

It has a serial communication for connection to Sitrad.

Evolution line products has a frontal IP-65 protection, Flatec key for easy access, four digits display and exclusive accessories* as the key programmer EasyProg and the protective case Ecase.
