JetMove 203-230 11.1 Function
Jetter AG 77
11 Analog Input (Option)
11.1 Function
For the JetMove 203-230, an optional integrated analog input card can be ordered.
This card supplies an analog input of a 12 bit resolution. The converted value of the
analog voltage can be read via a register of the JetMove in the PLC program or
processed by the firmware of the JetMove in an additional controller. This way it is
possible for example, to realize a pressure control loop in which the motor controlled
by the JetMove generates the pressure. A pressure sensor in the machine is
connected to the analog input to deliver the actual pressure value for the control loop.
This option can only be ordered as an alternative to the Ethernet connection (option
OEM).
