The unit has 4 digital and 4 analog 4 - 20mA inputs. With the mains powered version, the analog inputs are galvanically isolated to eliminate the risk of interference with your existing cabling and systems. The digital inputs contain 3 status / counter / pulse inputs and 1 coil input for e.g. a flowmeter. The sensor inputs can be easily expanded with approx. 10 Modbus slaves through a RS485 communication port or the SDI-12 protocol. One RS232 is also available.
The generated data by the M844 is send through TCP, FTP and/or email. Total control can be gained through the fully integrated ProcessMonitor web-portal or the ProcessView stand-alone software package. Alerts and alarms are send by SMS with adjustable increased logging frequency. Internal diagnostics may send alarm messages including battery capacity, temperature and GSM signal strength.
