  • Precision discrete temperature setting (through 10C)
  • Wide range of controlled temperatures –55 ...+1250C
  • Ability to work in mode "heating" or "cooling"
  • Output contact - 1 switching group 16A/250V
  • Control of sensor serviceability
  • Switching hysteresis 0,5 or 20С
  • It works with digital temperature sensors DS18B20 Dallas Semiconductor (Maxim)
 
PURPOSE OF THE RELAY
 Temperature relay TR-15 is designed to control and maintain the preset temperature mode at the temperature sensor signals, generated on the basis of the chip DS18B20 Dallas Semiconductor (Maxim) in the premises, vegetable storage, water heating systems, cooling systems, liquids, objects, and so on, and also for use as components in the automation devices. Temperature relay is supplied with sensors TD-2 (specify when ordering).
 
DESIGN OF THE RELAY
 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: DIP-switch for setting the hysteresis zone «Δ0,5/Δ2», to select the "00C\+100", to set a positive or negative temperature "+t0C/-t0C", to select mode cooling/heating, rotary switch "TENS" to set the tens of temperature, rotary switch "UNITS" to set the temperature unit, the red LED "+t0C" of heating, blue LED "-t0C" of cooling, yellow LED of actuation built-in executive relay "" .
 
OPERATION OF THE RELAY
 Termorele can work in two modes: "heating" or "cooling".
 "Heating" - a mode in which the executive relay is turned on, if the controlled temperature is below the set (heater).
 "Cooling" - a mode in which the executive relay is turned on, if the controlled temperature exceeds the set limit (fridge). The operating mode is selected by the switch "cooling/heating".
 Enabling of the executive relay is controlled by a yellow indicator "". When the relay is turned on, the yellow LED lights up and the contacts 11-14 are closed. In "heating" mode when power is turned on, if the temperature in the controlled point will be below set, the relay will turn on. Upon reaching the set temperature (t0Cset) - the relay will switch off. When cooling, the re-activation of the relay will take place at t0Cset - Δ. In the "cooling" mode at power up, if the temperature in the controlled point will be above the set, the relay will turn on. Upon reaching the set temperature a relay turns off. At the next time of the temperature increases, the relay will turn on at temperature t0Cset+ Δ.
 
 WARNING: If using more that 3500W power devices is recommended to use intermediate relays or contactors, the appropriate load.
