ADH300 module is used as PLC expansion module, complete 12 AC current, 4 leakage resistance and 1 system voltage measurement. The 12 AC current inputs are divided into four groups. The three AC current inputs in each group are connected to the three-phase AC current of each branch of the combined switch. This module can realize 4 combination measurement, and can realize the branch measurement of 6, 8 and 12 second-class combination switches through expansion. The product fully considers the precious installation space in the equipment control box, and has the characteristics of small volume and powerful function.
As an expansion module, this module, together with the CPU module, realizes the control of the starting switch of various equipment in the mining area and other working faces. When the equipment fails, such as overload, short circuit, overvoltage and undervoltage, it can automatically cut off the power supply and display the fault signal, and has the function of leakage lock and test before closing. The current value and voltage value of each branch can be displayed during operation; With undervoltage, overload, phase loss, short circuit and leakage blocking protection; The controlled motor can be controlled by single machine, single machine, dual speed, dual speed, etc. All kinds of motors can be started and stopped, and the motor and power supply line can be protected to achieve the purpose of automatic control of power supply equipment on the working face.
