Watlow unveils temperature/process controller
A
Watlow product story
Edited by the Engineeringtalk editorial team
Nov 11, 2008
Watlow has introduces the EZ-zone RM - a configurable multi-loop temperature/process controller that integrates an entire assembly of control loop functionality in one Din-rail mounted package.
EZ-zone RM can be used as a PID temperature/process controller, an over/under limit controller, or these functions can be combined into an integrated controller.
Other control functions can be integrated such as high amperage power controller output, creating a complete and integrated thermal loop controller in one package.
EZ-zone RM can be configured with between one to 16 modules controlling from one to 64 loops.
As the controller is single-loop scalable, customers pay only for what they need - exact loop count.
Utilising an integrated controller solution reduces wiring time and termination complexity.
In addition, integrated controllers reduce troubleshooting time and downtime costs since the system can specifically identify to the operator if there are any problems with a sensor, controller, solid state relay (SSR) power output or heater load.
EZ-zone RM allows for optional integrated controller functions to be combined together or ordered in different quantities including: sequencer start up and control function; programmable timer and counter functions; programmable maths and logic options; multiple communication protocol options; mobile configuration with removable secure digital flash card; and Split-rail configuration to isolate low-voltage input modules from high-voltage output modules.
EZ-zone RM offers current monitoring for the entire system, on-board data logging, sensor back-up capability and Tru-Tune+ adaptive control, which provides tighter control for demanding applications.
Its communications capabilities feature a range of protocol choices including a USB device port, Ethernet/IP, Modbus RTU, Modbus TCP, Devicenet and Profibus.
The EZ-zone RM shares a common user interface, menu structure, wiring and connector labelling, plus user manual support documentation with other members in the EZ-zone range.
This controller is suitable for semiconductor processing, photovoltaic, packaging, plastics processing and a variety of other applications that require multi-loop control.
