Page
The IO 112 is a measuring module and a 1-channel
protection unit for use in connection with the MP 204
6
motor protection unit. The module can be used for
6
protection of pump against other factors than the
7
electrical conditions, for instance dry-running. It can
7
also be used as a stand-alone protection module.

The IO 112 interface has
7
• three inputs for measured values
7
• one potentiometer for setting of limits
7
• indicator lights indicating the
7
- measured value of the input
7
- value of the limit set
7
- alarm source
8
- pump status.
