Connecting to an External Device

■ Connection

* Recommended communication cable:

KPEV-SP(1P) wire with balanced type twisted shield (strand wire)

Nominal cross-section area 0.16mm

(AWG25) min.

A terminal cover is attached to the terminal block. After

performing the wiring, be sure to reattach the terminal cover.

● Crimp-type terminal

Use Y or round terminals for wiring to the I/O terminal of the following sizes.

Y terminal

Round terminal

■ Wiring

To connect to an external device including a PC,

refer to the following wiring diagram for connection.

• The cable to be used for communication should be

15m or less.

• Be sure to connect the shield wire of the shield cable

to the SG terminal on the external device.

• The shield wire connected to SG terminal should not

contact with other signal cables or terminal blocks.

■ Input circuit diagram

* Pin No. 1, 4 and 5 (SG) are common to the 0V blue wire on the main

sensor amplifier.

Communication Settings

Use the communication setting switch for communication settings.

• After changing the

communication settings, be

sure to cycle power.

• After setting, reattach the

included switch protection

sticker.

Terminal No. Terminal symbol Description

cable. Terminals 1, 4 and 5 are internally

connected.

2 RD (input)

Connect to SD of an external device with the

communication cable.

3 SD (output)

Connect to RD of an external device with the

communication cable.

4 SG Terminals 1, 4 and 5 are internally connected.

6 DRQ (input)

If terminals 6 (DRQ) and terminals 1, 4 or 5 (SG)

are short circuited, data is transmitted without a

command from an external device.
