Features & Benefits:

Features Benefits
4 to 192 loop limit controller
  • Eliminates compatability issues often encountered with using many different discrete components and brands
  • Saves engineering time and labor costs while shortening project schedules
  • Allows a common limit controller platform across many design applications
  • Allows standard bus communications
  • Ability to utilize EIA 485, Modbus® RTU options
SPLIT-RAIL control
  • Minimizes the length and cost of wire runs and improves system reliability by locating inputs closer to sensors and outputs closer to loads
  • Prevents unplanned process shutdowns and product loss by switching to a backup sensor if the primary sensor fails
  • Saves time and reduces complexity by automatically configuring a new module with the same parameter settings as the replaced module
