Dual Zone Temperature Controller - 20A & 8A Relays - 2 Sensors Included - EU Seller

Key Features:

  • Integrated Dual Temperature Control: Manage two separate heating or cooling zones with one device.
  • Two Temperature Sensor Inputs: Comes with two high-accuracy temperature sensors for precise monitoring of two locations.
  • Powerful Relay Outputs: Features a 20A relay and an 8A relay for controlling high-power devices.
  • Alternating Temperature Display: Clear digital display alternates between T1 and T2 temperature readings.
  • Mathematical Temperature Functions: Calculate average and differential temperatures for advanced control applications.
  • Interlocking Relay Logic: Configure relays to operate in relation to each other (e.g., one on when the other is off).
  • External Digital Input: Allows for manual override or connection to fault detection systems.
  • Built-in Audible Alarm: Provides instant alerts for temperature deviations or system errors.

Ideal for:

  • Heating and cooling systems
  • Incubators and terrariums
  • Industrial temperature control
  • And more!

Includes:

  • Dual Channel Temperature Controller
  • 2 x Temperature Sensors
  • User Manual

Universal controller designed to temperature control in heating systems:

DC20 - Dual Zone Temperature Controller Features:

  • Dual Controller Design: Two independent temperature CONTROLLERS housed in one casing, with flexible input/output configuration and interconnectivity.
  • Versatile Input/Output: Features 2 control inputs and 2 control outputs, supporting both HEATING and COOLING modes. Measurement can be sourced from T1, T2, or both sensors simultaneously.
  • Advanced Mathematical Functions: Calculates differential [T2-T1] (ideal for solar collectors) and average [T1+T2]/2 temperatures from dual sensor inputs.
  • Flexible System Integration: Suitable for simple, single, dual, and complex heating or cooling system applications.
  • Digital Temperature Display: Digital temperature reading and display calibration, with alternating T1 and T2 readings every 3 seconds (single reading display).
  • Audible Output Signaling: Built-in sound signaler for output activation and emergency alerts.
  • Multi-Functional Digital Input: Configurable as alarm input or manual mode control, capable of signaling system failures via external pressure switches or STB temperature limiters. System lockout with manual reset option.
  • High-Power Relay Outputs: Equipped with 1 x 20A and 1 x 8A relays.
