Watlow Ez-Zone RM multiloop temperature/process controller

Watlow has introduced the Ez-Zone RM, a configurable multiloop temperature and process controller. The Ez-Zone RM 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 as well, such as high amperage power controller output, creating an integrated thermal loop controller in one package.

The controller can be configured with between 1 to 16 modules controlling from 1 to 64 loops. Because 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, improves overall system reliability, reduces termination and installation costs, and eliminates compatibility issues encountered when using many different components and brands. 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 offers current monitoring for the entire system, onboard 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 USB, EtherNet/IP, Modbus RTU, Modbus TCP, DeviceNet and Profibus.
