What is the difference between DYNEO “base model”, digital and analog?

The standard Dyneo DD (base model) is supplied with a USB communication interface and an External PT100 sensor input.

The Dyneo DD with the .D (“digital”) option would have an additional RS232 connection installed in addition to the standard connections.

The Dyneo DD with the .A (“analog”) connections installed would have the Standby, Alarm output and REG+EPROG connections in addition to the standard connections.
