Omron E5EZ-PRR Series User Manual

Digital Position-Proportional Controllers E5EZ-PRR 29
Digital Position-Proportional Controllers
E5EZ-PRR
A position proportional control model for the E5@Z-PRR series
• Just 78mm depth
• All types of input: temperature input type, analog (current, voltage) input
type
• Makes use of high-visibility LCD, with three lines of 4-digit display, for
simplicity and clarity
• 3 lines of display to observe PV/ SV/ MV (percentage of valve's opening),
clearly displaying the state of control (operations)
• Event input enables the selection of multi configurations as well as a
start/ stop function
• Alarm delay function
• Communications function
• Able to choose floating control or closed control. In floating control,
position proportional control can be realized without a potentiometer
• Equipped with a manual output function (equipped with an automatic/
manual key)
