Digital Controller

E5AK/E5EK

19

Polarities during no-contact input are as follows:

Transfer Output

Connect transfer output (TRSF) to terminal numbers 21 and 22. The internal equalizing circuit for transfer output is as follows:

Transfer output specifications are as follows: 4 to 20 mA,

Permissible load impedance: 600

Ω max.,

Resolution: Approx. 2600

Communications

Terminal numbers 18 to 22 can be used only on controllers with Communications Units (E53-EN01/02/03). For details on wiring, refer to Chapter

6, Using the Communications Function in the E5AK/E5EK User’s Manual (H83/H85).

■ Precautions when Wiring

Use ducts to separate input leads and power lines in order to protect the Controller and its lines from external noise.

Solderless terminals are recommended when wiring the Controller.

Tighten the terminal screws using a torque no greater than 0.78 N·m, or 8 kgf·cm max. Take care not to tighten the terminal screws too tightly.

Power Blocks

The E5AK/E5EK has independent power supplies for each of the terminal blocks shown below.

Note: Terminals 21 and 22 of the E5EK belong to the B block when a

transfer output is set to option 1 and to the C block for other Op-

tion Units.
