The Watlow EZ-ZONE RM Expansion controller simplifies thermal system management. The EZ-ZONE RM controller family is comprised of six module types: an integrated on-off or PID control, monitoring and over/under temperature limit module, a high-density on-off or PID control module, a high-density limit only module, an input/output (I/O) expansion module, a high-density monitor/scanner module and a data logging and field communications access module. A system is configured by connecting any combination of module types to address specific application needs. The EZ-ZONE RM is extremely flexible and scalable allowing mixing and matching of I/O to configure 1 to 152 control loops and up to 256 monitor points.
 
Features
PID control loops
Over/under temperature limit control loops
10 and 15 ampere power output/heater driver options
On-board data logging
Current measurement input
Sequencer start up and control function
Programmable timer and counter functions
Programmable math and logic options
Multiple communication protocols options
Mobile configuration with removable secure digital (SD) flash card
 
Multiple inputs; from 1 to 152 PID loops of control or monitor up to 256 analog inputs
Mix and match I/O to fit any application; from 1 input with 2 outputs to 152 analog inputs with 152 outputs, or monitor up to as many as 256 analog inputs all in one system
Reduces cost because only required loops are purchased
Allows a common controller platform across many design applications as both loops and outputs can be ordered in single increments
Additional Key Functions
Configuration communication port (standard bus)
Removable modules and connectors
Ring lug and front-screw terminal options
Profile ramp soak with 400 total steps
Retransmit and remote set point input virtually inside controller eliminating costs for input/output hardware
User configuration settings can be stored and recalled
Thermistor input
Elevated operating range of 0 to 149°F (-18 to 65°C)
