Description

XH-W1219 12V Digital Temperature Controller

The XH-W1219 12V digital temperature controller is a device that allows you to control the temperature of a system or process using a digital interface. It typically includes a temperature sensor, a control algorithm, and an output mechanism to control the temperature. The XH-W1219 is a 12V version, meaning that it operates at a voltage of 12V DC. It may have inputs for setting the temperature setpoint and control parameters, as well as outputs for controlling devices such as heating elements or cooling fans. The controller may also have a display for showing the current temperature, setpoint, and other information. It may be used in a wide range of applications including HVAC systems, incubators, ovens, and other temperature-controlled environments.

The XH-W1219 module is basically the same as the popular W-1209 module except it has a 2nd display added to always show the current trigger point along with the current temperature.   When programming the parameters in the module, the dual displays make it a little easier see what you are doing since the top display shows the parameter selected while the bottom display shows the value you are setting.  This module is slightly larger than the W-1209 and so will not fit in the acrylic case designed for that module.

A built in STM8S uC allows you to configure the module using the display and 3 pushbuttons.  All settings are saved into non-volatile memory and are preserved during a power cycle.

The temperature is sensed by a high accuracy waterproof NTC 10K Thermistor that has a range of -30°C to 110°C (-22°F to 230°F) .  The sensor cable is about 13? long, but it is possible to splice wire to lengthen the cable if needed.

The relay is rated for up to 120VAC @ 10A and 14VDC @ 10A.  When the relay is energized an LED is lit.    It is also possible to use the relay on this module to switch higher power relays if you want to control a lot of power.

Note: This board is Nuvoton based.

Button Parameters:

  • P0 = (Heat / Cool) sets whether the relay is energized or de-energized when trigger temperature is reached.
  • P1 = (Hysteresis) sets the difference in degrees between the Trigger temp and when the relay changes state
  • P2 = (Max Temp) sets the maximum Trigger temp that can be set
  • P3 = (Min Temp) sets the minimum Trigger temp that can be set
  • P4 = (Temp Correction) sets an offset to use for the displayed value
  • P5 = (Delay) sets a time delay between when the Trigger temp is reached and when the relay is switched
  • P6 = (Alarm) sets a high temperature ‘alarm’ trip point
