YDOC Remote Monitoring Station
The YDOC Remote Monitoring System is comprised of a YDOC ML- series data logger, solar charge controller, 7.2Ah 12 volt battery and a sensor bus bar; all enclosed in an IP66 rated, UV stable box designed for installation in a range of environmental conditions.
- Expanded power system for a greater number of high power draw sensors
- 2G/3G/4G Cellular Data Logger
- 4GB Data Storage
- Analog & Digital Inputs
- Derived Inputs
- RS232, R485 & SDI-12
- ASCII, MODBUS & NMEA-0183
- TCP, FTP(S), HTTP(S), e-Mail, MQTT
- CSV, TXT, JSON & JPG Files
- Alarm Output & SMS
- Remote Configuration
The data logger can acquire physical signals by 2 current loop inputs, 2 voltage inputs, 1 potentiometer input and 3 digital inputs. More or special inputs can be added by means of internal stackable option boards/converters.
The data logger is provided with one serial port to capture measurements from ASCII, MODBUS, NMEA or SDI-12 compatible sensors. External sensors can be powered by the data logger itself. Up to 8 mathematical channels are available to calculate meaningful engineering values derived from sensor input values (e.g. a polynomial to calculate a flow from a stream level). Supports up to 8 aggregation channels (e.g. to record 2 or 10 minute wind-speed averages sampled at 1Hz).
Logged data can be pushed to a central host by HTTP(S), FTP(S), e-mail, secure TCP or MQTT at configurable intervals and optionally by satellite as well (Iridium SBD).
The ML-x17 is available with 4 different cellular modems:
• ML-217: 2G Global
• ML-317: 3G Global with 2G fall-back
• ML-417: 4G Europe with 2G fall-back
• ML-N417: 4G North-America with 3G fall-back
