PLASTX temperature controller and indicator for extruder applications

 Simple to operate  Universal input  Selectable controller or indicator modes  Heat only or heat cool control type  Process & loop alarms  Available in 1/16 & 1/8 DIN formats  Modbus RS485 communications  Ramping setpoint

Reduce inventory – single device for heat only, heat/cool control and indicator Fast configuration – plastic extruder specific settings and default parameters to fit the selected mode

The Plastx extruder temperature controller from West Control Solutions is an economic solution to precision temperature control of extruders. With two package sizes and multiple output configurations, the controller is suitable for twin and single screw extruders, both heat only die and adapter zones, in addition to heat cool for barrel zones. The instrument can also be used in an indicator only mode, allowing one instrument to be used for all applications. With three default parameter sets for Indicator, Heat and Heat/Cool modes, the Plastx controller offers the ultimate in flexibility for the control of industrial plastic extruders.
