About the power
blocks
2--10
• Terminal Nos.3 and 4 are for auxiliary output 1 (SUB1) and terminal
Nos.1 and 2 are for auxiliary output 2 (SUB2).
• The internal equalizing circuits for the auxiliary outputs are as fol-
lows:
• Output specifications are as follows:
SPST-NO, AC250V , 3A
• When using the HBA function on the E5EK-AA2 controller, connect
CT input (CT) to terminal Nos.15 to 17. When monitoring the valve
opening on the E5EK-PRR2 controller, connect the potentiometer
(PTMR) to terminal Nos.15 to 17. Connect each of these inputs as fol-
lows:

CT input
• For details on CT inputs, see Appendix, About current transformer.
• For details on the potentiometer, see the Instruction Manual for the
valve connected to the controller. The variable resistance range is 100
Ω to 2.5 kΩ.
• Connect an input (RSP) to be used as the remote SP to terminal
Nos.15 and 16. However, note that the remote SP can not be used on
the E5EK-PRR2 controller.
• Only 4 to 20 mA inputs can be connected. Connect the input as fol-
lows:
The E5EK has independent power supplies for each of
the terminal blocks shown on the right.
