electronicindustrialresidential

The KET-MES-420 is a device with 4G-LTE modem, which, via the KET-IOI-100 photodetector, counts the pulses related to the consumption of energy drawn from and fed into the electricity grid, and can be configured via simple commands sent by SMS. In addition, via the 4 digital inputs, the RS485 ModBUS RTU interface and the TCP/IP server it can interconnect with various industrial devices, such as PLCs, gateways, sensors, ect. Ability to set multiple timers (second, minute, day, week, month) to perform actions, such as data uploading. Equipped with an internal battery that lasts 8-20 hours, the modem enters 'sleep' mode in the event of a power failure.
