Controller
The E5AK 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 temper-
ature 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) function
on a standard type controller (E5AK-AA2).
· Connect the potentiometer when monitoring the valve opening on a
position-proportional type controller (E5AK-PRR2).
When the remote SP function is enabled, inputs within the range 4 to 20
mA are used as the remote SP .
