The E5EK supports following inputs: temperature input, current input,
voltage input, CT input/Potentiometer, remote SP input and event
input.
F Temperature input/Voltage input/Current input
• Only one of temperature input, voltage input and current input can
be selected and connected to the controller. The above figure shows
temperature input connected to the controller.
• The following input sensors can be connected for temperature input:
Thermocouple:K,J,T,E,L,U,N,R,S,B,W,PLII
Platinum resistance thermometer: JPt100, Pt100
• The following currents can be connected for current input:
4to20mA,0to20mA
• The following voltages can be connected for voltage input:
1to5VDC,0to5VDC,0to10VDC
• Connect CT input when using the HBA (heater b urnout alarm) func-
tion on a standard type controller (E5EK-AA2).
• Connect the potentiometer when monitoring the valve opening on a
position-proportional type controller (E5EK-PRR2). However, note
that the potentiometer cannot be used simultaneously with remote
SP input.
• Remote SP input cannot be used simultaneously with potentiometer.
• When the remote SP function is enabled, inputs within the range 4 to
20 mA are used as the remote SP.
