MES PI4 Machine Connection
PI4 connection boxes can be used on all machines to capture different signals off electrically.
- Universal connection: it has four inputs (eg. one production signal and three stop reasons)
- Robust: thanks to protected inputs and ouputs
- Recording of measured values: modules with analog inputs available
- Control signals: modules with digital outputs available
Recording of signals
PI4 modules are used for capturing or controlling signals of a machine electrically.
- digital keys
- signals for material change
- direction of rotation
Robust
The PI4 modules are integrated in a transparent polycarbonate housing. This protective shell allows an easy control of function and wiring at any time.
The inputs and outputs are protected against overvoltage and have a current limit.
Connection of the PI4 to the machine station
1 to 16 PI4s max can be connected to a machine station (MS7, MS4). The PI4 is placed and wired in the machine. The communication between PI4 module and machine station is made via the IOBus (cable: 4×0.34mm, shielded).
