P304 ¼ DIN Melt Pressure Indicator / Controller

Specifications

Both the piccolo™ P304i Melt Pressure indicator and P304c controller have a 50ms sample rate to give the fast-acting control and alarm functionality required in the plastics industry. The P304c controller provides outstanding control performance in an affordable package for a wide variety of pressure sensors.
Input/output flexibility

A strain gauge or process linear input is standard with an optional strain gauge input for differential pressure control, or a universal input for remote setpoint. Up to two opto-isolated DC linear outputs are available for control or retransmission along with one standard logic input for alarm reset/acknowledge or zero calibration of sensor. An additional four logic inputs may be selected for remote activation of functions like auto/manual mode selection and increase/ decrease of power output.

The display

A custom, dual-line 5-digit display provides a complete view of the process while a horizontal bar graph gives clear visual indication of the process input. The status of alarms, outputs, active setpoint and engineering units are represented with clear beacons on the front of the unit.

Configuration

The P304 is fully software configurable using iTools PC configuration and parameter monitoring. iTools provides the ability to edit, store and ‘clone’ complete controller configurations as well as data logging and process monitoring capability.
