Additionally 6 digital in/outputs and 2 relays outputs are available. Data access, I/O expansion, and configuration can be done via any of the communication interfaces RS 485 (3x), RS 232, or Ethernet. Configurable logging intervals from 1s up to 24h and measurements can be logged into a 16 MB RAM or a 128 MB flash memory. A selectable sleep mode causes the logger will wake up for one measurement and go to sleep again after storing the results. This extremely low power usage and make the unit great for autonomous applications. Built-in PAC functionality provides complete programmability with built-in functions like sequencing, controlling mathematics and Boolean combinations. I/O expansion is possible by adding any standard e.bloxx modules on the built-in RS-485 bus interface.
