Çok Girişli Yangın Önleme Cihazı
The AcuRC 420 can simultaneously monitor 12-channel current (residual current or line current), 4-channel temperature and 3-phase voltage. When a current (residual current or line current) alarm or temperature alarm
generating, it can issue sound and light alarm, and the relay will output. The monitoring center will read the alarm massages and DI status through RS485, and record the residual current or line current or temperature alarm value and the time of occurrence. Residual current, current, temperature, voltage alarm threshold value and delay time can be setted through the external display module or communication. Several monitors and a monitoring center can be an electrical fire monitoring system through RS485 link using MODBUS protocol.

Introduction
The residual current monitors (RCMs) AcuRC 410 series continuously monitor the level of the residual current in earthed system (TN and TT systems), according to the standard of IEC62020, IEC60755, IEC60364. The devices are intended to be used in AC systems. Both single-phase and three-phase systems can be monitored. They can also be used for current monitoring of single conductors, which in normal operation carry no current, such as PE, Nconductors. In addition, AcuRC 412 measures line voltage or phase voltage, while AcuRC 413 measures temperature. The AcuRC 410 series monitor, with four keys and LCD display, is convenient for you to get all the parameters of residual current. The parameters can also be centralized on a PC or PLC through RS485 link using MODBUS protocol.
