•
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, 250 VAC, 3 A
•
When the HBA function on an E5EK-TAA2 controller is used, connect
CT input (CT) to terminal Nos.15 and 17. When monitoring the valve
opening on an E5EK-TPRR2 controller, connect the potentiometer
(PTMR) to terminal Nos.15 to 17. Connect each of these inputs as fol-
lows:

For details on CT inputs, see Appendix, About Current Transformer
(CT) Input (page A-5).
•
For details on the potentiometer, see the Instruction Manual for the
valve connected to the controller.
The meaning of terminal symbols is as follows:
O: OPEN, W: WIPE, C: CLOSE
The variable resistance range is 100
Ω
to 2.5 k
Ω
.
The E5EK-T has independent power supplies
for each of the terminal blocks shown on the
right.
