HE-230 controller is designed to control a set of heaters (up to 6 three-phase heaters) of an electric heater.Depending on the demand, the module issues a signal controlling the switching on of an appropriate number of heaters for continuous operation, and one heater is controlled by a PWM signal with a period of 1¸10s. The number of attached heaters and the degree of PWM signal control is determined by the signal at the analog input 0¸10V (taking into account the current power limitation). The device is equipped with one digital input working in the mode of an external signal allowing the module to work.
Power supply: 230 V AC
