REMOTE POWER SUPPLY CONTROL APPARATUS OF PLC SYSTEM, IN WHICH ABNORMALITY SENSING MODULE GENERATES SWITCHING POWER SUPPLIED TO A POWER SUPPLY MODULE

摘要

PURPOSE: A remote power supply control apparatus of a PLC(Programmable Logic Controller) system is provided to simplify system configuration and to reduce installation cost, by turning on/off a power supply without installing a power supply control PLC system additionally. CONSTITUTION: A power supply module(11) supplies power to the whole system. A CPU module(12) controls the operation of the whole system. A communication module(13) transmits and receives every command with other system and apparatus according to the control of the CPU module. An input/output module(14) inputs/outputs data with a control target device(15) by the control of the CPU module. An abnormality sensing module(20) outputs a switching control signal by sensing abnormality. And a switching module(21) controls on/off of the power supplied to the power supply module.
