Event Input

Connect event inputs 1 and 2 (EV1/2) to terminal numbers 18 to 20, and event events 3 and 4 (EV3/4) to terminal numbers 24 to 26. However, note

that terminal numbers 18 to 20 cannot be used on Controllers with a communications function. Connect the event inputs as follows:

Terminals 18 and 24 (COM) are connected internally.

Use event inputs under the following conditions:

Polarities during no-contact input are as follows:

Transfer Output

Connect transfer output (TRSF) to terminal numbers 29 and 30. 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 20, 31 and 32 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).
