IO 112 Description Product number
The IO 112 is a measuring module and a 1-channel protection unit for use in
connection with the MP 204 motor protection unit. The module can be used for
protection of pump against other factors than the electrical conditions, for
instance dry-running. It can also be used as a stand-alone protection module.
The IO 112 interface has three inputs for measured values one potentiometer for
setting of limits indicator lights indicating the
• measured value of the input
• value of the limit set
• alarm source
• pump status.
