Technical Specifications

Input Signals

The PFEA 111/112 can accept a variety of input signal types and ranges. They are typically designed to interface with load cells that provide analog signals such as 4 - 20 mA or 0 - 10 V, representing the measured tension. The units also have the ability to handle digital input signals for additional process - control information such as start/stop commands or speed references.

Output Signals

The control units provide output signals to drive actuators or other control elements. These can include analog output signals to control variable - speed drives (VSDs) in the form of 0 - 10 V or 4 - 20 mA signals, which adjust the speed of motors to regulate tension. They also have digital output signals for functions like activating alarms or indicating the status of the tension - control system.

Control Modes and Parameters

The PFEA 111/112 offers different control modes such as PID (Proportional - Integral - Derivative) control. The PID parameters can be adjusted to optimize the control performance according to the specific characteristics of the process and the material. For example, in a high - speed film - winding process, the derivative gain might be set higher to quickly respond to sudden changes in tension.
