The MPC-143 is a remote datalogger created for measuring and logging data from Modbus RTU devices, analog inputs (current, voltage, resistance or PT100 temperature sensors) and discrete inputs (pulses, alarms or events).

MPC-143 GPRS Modbus Datalogger with Analog and Pulse inputs

The logged information can be either collected remotely using standard and open protocol Modbus TCP/IP, through GPRS communication or sent in csv file format to remote FTP servers.

This controller is particularly suitable for Renewable Energy Plants Remote Monitoring applications such as Solar PV plants or Wind turbines.
