Double thermostat DTR01

DTR01 keeps independently for both channels set reference temperature with hysteresis 2°C. The relay has two normally open output contacts 16 A. Double thermostat DTR01 is supplied together with two NTC 3k3 sensors with the 3 m cable length.

  • two independent channels for temperature measurement
  • fix hysteresis 2°C
  • measuring temperature range -25°C ... 95°C
  • self test of connected temperature sensors
  • small dimension 1-DIN rail module
  • relay status LED signalization
If the set temperature value T is not reached, output relay R is closed. When requested set temperature is reached, relay R is disconnected. Reconnection of relay R is made at the moment of measured value decline under the set level T minus hysteresis 2°C. Hysteresis eliminates relay bouncing at boundary values of temperature. Each channel is totally independent.
