| Model Number | EM-486 |
| Brand | NOVATEK ELECTRO |
| Attributes | RS485 Modbus/ASCI to GSM/Ethernet conversion, Micro SD card |
| Application | Remote Monitoring/Control, IOT, Data Logging, 3 Relay Outputs & 4 Sensor Inputs |
Interface controller with built-in I/Os for Remote Operation/Monitoring EM-486 provides access to readings of communicable devices, gauges and sensors from their registers of Modbus connected via RS-485 interface with the help of text SMS messages, automatic data gathering from the selected devices, transmitting the gathered data via GPRS or Ethernet to various SCADA interfaces, automatic transmitting SMS alarms of state of selected devices.
EM-486 has:
EM-486 provides control for MODBUS devices in RS-485 network via Ethernet interfaces or GPRS, or via the SMS. The unit also allows to read data from devices by MODBUS or from connected sensors.
The processor supports connection to the accumulating data cloud server via Ethernet network with a help of micro chip of physical interface of Ethernet (or via GPRS with a help of inbuilt GSM-modem, if connection via Ethernet is not available).
In addition, EM-486 can be connected to Ethernet via MODBUS TCP Protocol to exchange data with MODBUS devices, or with the product. The controller receives and processes SMS with a password and command read/write for Modbus devices.
When inserting a memory card the product reads the internal memory for operational logic – program for data collection and tracking of events. The program runs in the background mode.
Product stores in the internal memory the network settings, parameters of inputs and outputs, the logic of action, the collected data log.
