Input Signals to Programmable Controller

The rate monitor system has two main input signals that it uses from the extrusion process: the weigh hopper load cell, and the extruder speed reference. This, of course, does not include the operator touch-screen input.

The extruder speed reference is generated from the supplied inductive proximity switch, or is wrote to the PLC through the optional Ethernet module.

Load cells require +12 volts DC to operate. This is known as the load cell’s excitation voltage.

Output Signals from Programmable Controller

The rate monitoring system uses several output control signals to control the process. All of these are very similar in nature.

The surge hopper refill solenoid is controlled by a PLC output.
