Controller
The E5EK supports following inputs: temperature input, current input,
voltage input, CT input/Potentiometer, remote SP input and event
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:
4 to 20 mA, 0 to 20 mA
• The following voltages can be connected for voltage input:
1 to 5 VDC, 0 to 5 VDC, 0 to 10 VDC
• Connect CT input when using the HBA (heater burnout 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 .
