124-1052 - 24V ac/dc, 1 output

Features and Benefits:


• Single set-point

• Zero point shift

• Probe failure setting, output status can be set to On, Off or pulse

• Sensor input offset setting

• Relay out for temperature control

• Compressor protection- delay timer

• CE Certified

Typical Applications:


On/Off temperature controllers are designed to control and maintain temperatures in appliances by turning on or off, depending on the users required pre-set temperature. If the temperature drops below the setpoint, the controller will turn on and increase the temperature until it is met. Once the desired temperature is reached, the device output switches off automatically. Temperature controllers are perfect for applications that require temperature control solutions, especially those whereby the temperature increases slowly, and are commonly used in areas such as:

HVAC systems

Ovens

Incubators

Automotive

Storage solutions

FAQs

Why use an On/Off Temperature Controller?

Used for monitoring purposes in heating environments, on-off temperature controllers prevent rapid increases in temperature that could cause damage. These controllers are often used where there isn't a need for precision temperature control, but where a system is unable to handle continuous interruptions. A typical example of an on-off controller is a thermostat in a system, if the temperature drops below the preset level the system is switched on. They can protect against a system over-heating or over-cooling and have an 'on' 'off' option with no middle state.
