Full Gauge MT-543EL Log Electronic Control for Cooling and Heating applications. 1 Sensor, 4 Outlet, Datalogger, 12/24V, Sitrad Compatible

FOUR-STAGE DIGITAL CONTROLLER WITH ALARM, CYCLICAL TIMER, SERIAL COMMUNICATION, AND HACCP FUNCTIONS

The MT-543EL Log controller has four stages that can be applied to refrigeration or heating: the first stage, together with the third stage, works in systems that require minimum ventilation; the third one works as a cyclical timer; the fourth one works as an alarm. The second, third and fourth stages work also in the following modes: refrigeration, heating, refrigeration (Sp1), heating (SP1) and refrigeration in rotation. It also has a fifth relay that can be used as power failure alert and / or alarm. The MT-543EL Log accepts three types of sensors: NTC thermistor (-50C to 105C*), PT100** and PT1000** (-200C to 300C). It has an intelligent functions lock system, a mode to switch off the control functions, an internal audible alarm (buzzer), and a configurable digital filter. It allows the stages to be used in an independent way or in rotation mode (alternating the outputs). It features an internal memory (datalogger), where the temperature value is stored in user-defined time periods, the temperature variation and the state of the outputs. In addition, it has built-in rechargeable battery and clock to keep track of data even in case of power failure and serial port for communications with Sitrad. It also allows monitoring of HACCP critical points (Hazard Analysis and Critical Control Point) by means of records in the controller's memory of high temperature alarm, power failure, and digital input.
