Components and Operation Instructions for Intelligent Temperature Control Cabinet

Browse number: ...
Release time: 2026-10-23

The instrument-type intelligent temperature control cabinet is a dedicated supporting temperature control cabinet for electric heaters. It mainly consists of a cabinet enclosure, temperature regulators and electrical components. The temperature control system supports multiple instrument control modes for users to choose from, including on-off control, solid-state relay voltage regulation control and SCR continuous adjustable control. It is designed to maintain a highly stable outlet temperature for heating and its temperature control accuracy can fully meet the process heating temperature requirements of users.

The operation instructions for each component are detailed as follows:

The monitoring unit comprises a display circuit and a control fault output section. The display circuit includes three-phase ammeter and voltmeter indication, display of process temperature and set temperature, soft start and stop, manual/automatic switching control, maximum output limiting function, overcurrent protection, etc. When the monitoring instruments detect a fault, a fault contact signal will be sent to the heating circuit to shut down the heating system, accompanied by fault indication and audible & visual alarm for further protection of heating elements.
The execution control unit mainly consists of the main circuit switch, voltage regulation mechanism and current-limiting fuse circuit. The main circuit switch can be selected properly according to current parameters and different protection functions. It controls the power current of the heater to switch the heating on and off. The voltage regulation execution unit has three types: contactor on-off control, solid-state relay voltage regulation control and SCR continuous adjustable control. The specific type shall be selected based on the on-site heating medium and control requirements. You may contact our electrical engineers for guidance on their differences and proper selection.
The operation unit is used for heating start, stop, emergency stop, overtemperature fault reset, temperature adjustment and setting. The specifications of this unit can be customized according to user requirements.
In addition, the temperature instrument power distribution cabinet can be supplied in indoor, outdoor, explosion-proof and non-explosion-proof versions based on the installation location.
