The MT-512E2HP features a single relay out-put, 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-512E2HP 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. Additionally, through an intelligent functions locking system, it prevents unauthorized people from changing the control parameters.

In addition to those features, the MT-512E 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.

For frozen goods, it automates the defrosting process according to the needs of the facility (intelligent defrosting), providing energy savings. It operates with two sensors, one for room temperature and the other, fastened to the evaporator, that controls defrosting completion and fan restarting. The room temperature control has a normal setpoint and an economy setpoint, in addition to the fast freezing functionality and alarm functions indicating that the door is open. It features up to two digital inputs. One of these inputs may be configured as sensor 3* to monitor the condenser temperature and disconnect the control outputs in case of an alarm. It also features a digital filter, which is intended to simulate an increase of the mass of the room temperature sensor (S1), thus increasing its response time (thermal inertia), and avoiding unnecessary compressor activations. Its 16-Amp relay output can control compressors of up to 1 hp and the defrost output has a current capacity of 10 Amp.

The TC-960Ri LOG is a temperature controller for frozen goods that automates the defrosting processes in accordance with the needs of the facility, Increasing energy efficiency. It has two sensors: one for ambient temperature and the other fixed to the evaporator that controls the defrosting ending and the fan restarting. It is also fitted with an alarm output and buzzer that can be activated by different events. It is fitted with two digital inputs, the ability to read the supply voltage (protecting the loads from under- and over-voltage), and an hour-meter function that indicates when the time for compressor maintenance has come. It also has a digital filter for the temperature reading that decreases the response time of the ambient sensor to reduce the compressor action by fast changes of this measurement. All the stored data is readily accessible via Sitrad software.

The MT-530 Super features three outputs: one for temperature control, one for humidity control and a third auxiliary output that can be configured to command a second stage temperature or humidity control. This controller is intended for low and medium relative humidity (10-85% non-condensing), and it also features an audible alarm (buzzer). Its temperature and humidity sensors are combined in a single bulb, saving space and wiring of the installation. Additionally, it includes an intelligent functions locking system to prevent unauthorized people from changing the control parameters. The instrument has serial communication for connection with the ® via Internet.

The MT543EPlus has four configurable outputs: cooling, heating, minimum ventilation, and alarm and timer (cyclic timer). It has an internal audible alarm (buzzer), a configurable digital filter, and accept three types of sensors: NTC thermistor (- 50 to 105°C), PT100, and PT1000 (- 99 to 300°C). MT-543E plus allows the use of stage 1 in soak mode and the configuration of up to five different setpoints and the time each setpoint will remain active. It has serial communication for connection to Sitrad.

The CONV32 INTERFACE allows for Full Gauge controllers, equipped with serial communication, to be connected to a PC that has a USB serial communication port. The interface then takes care of the transformation of the voltage levels used by the PC to RS-485 voltage levels used by the controllers. Full Gauge uses a RS-485 network to make the communication between the controllers and Sitrad Software more rugged and reliable. The communication is made over two wires (A and B), allowing to perform half-duplex communications, where the PC is master and controllers are slaves.

This serial device is used to transform the RS-485 standard to Ethernet signal (internet or intranet) thus allowing the controllers to communicate with Sitrad software through wiring connection (RJ-45). It also allows connecting instruments remotely. Through the IP address of the TCP-485 Ethernet module, it is possible to access it wherever it is inside the company’s network or on the internet.

This converter enables communication between Full Gauge Controls controllers and Sitrad through a WiFi data network using the standard TCP/IP communication the same as the TCP485. However, the TCP-485 WiFi does not require Ethernet cabling to manage the installation.
