P304 ¼ DIN Melt Pressure Indicator/Controller ... outstanding performance in an affordable package The Eurotherm piccolo™ P304i Melt Pressure indicator and P304c controller offer versatile solutions with advanced features and a wide range of hardware options that make them ideal for all types of plastic processing. Both units 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. 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. The P304 is fully software configurable using Eurotherm iTools PC configuration and parameter monitoring. Eurotherm iTools provides the ability to edit, store and ‘clone’ complete controller configurations as well as data logging and process monitoring capability. Control Optimise Simplify Easy to integrate and use in new and legacy applications Fast-acting alarms to protect against overpressure Responsive, precision PID control with overshoot inhibit Easy, effective auto-tune Universal + strain gauge inputs Second input for differential pressure indication / control Analogue retransmission Easy and flexible configuration via PC software or front panel Modbus RTU digital communications High visibility three colour LED display Wipedown, customizable front fascia High reliability and quality Three year warranty Ideal for • All types of plastic processing applications includi

P304i Melt Pressure Indicator The P304i is a fully programmable indicator with a single input configured for melt pressure measurement and the choice of wiring either strain gauge or amplified transducers to the unit. An optional second input provides an additional facility for differential pressure measurement if required. The update time for each channel is 50ms to respond to very fast processes. To provide full process measurement, the second input can be configured for either Thermocouple or RTD temperature measurement. Three preconfigured and ready to use alarms are associated to the...
