PROBLEM TO BE SOLVED: To provide a device for controlling a hot runner using a programmable controller which simplifies design control to be performed efficiently in a short period and enables miniaturization and cost reduction. SOLUTION: The device is used for an injection molding apparatus in which a molten resin can be injection molded from the hot runner into a desired cavity through a gate. The device for controlling the temperature of the hot runner uses the programmable controller which controls the temperature of the hot runner by using a temperature control module 7 and a programmable controller 15 having a power source module 4. a CPU module 5, an input/output module 6, etc.
