5.2.2 Selecting Cables
Controller cables: All cables laid in the controller must be capable of withstanding 70
o
C. In addition.
Power Signal: Shielded cable with an area of at least 0.75mm
2
or AWG 18.
Note that any local standards and regulations concerning insulation and area must always be
complied with.
Control signals: Shielded cables.
Measuring
signals:
Shielded cable with twisted pair conductors.
Data communica-
tion signals:
Shielded cable with twisted pair conductors.
A specific cable should be used for Gateway (Fiel bus) connections.
CAN bus with
DeviceNet for dis-
tributing I/O units:
Thin cable according to DeviceNet specification release 1.2, must be used, e.g. ABB article
no. 3HAB 8277-1. The cable is shielded and has four conductors, two for electronic supply
and two for signal transmission.
Note that a separate cable for supply of I/O loads is required.
Allen-Bradley
Remote I/O:
Cables according to Allen-Bradley specification, e.g. "Blue hose", should be used for connec-
tions between DSQC 350 and the Allen-Bradley PLC bus.
Interbus-S: Cables according to Phönix specification, e.g. "Green type", should be used for connections
between the DSQC 351 and external Interbus-S bus.
Profibus DP: Cables according to Profibus DP specification should be used for connections between the I/
O unit DSQC 352 and the external Profibus DP bus.
Ethernet: Shielded twisted pair conductors (10 Base T STP).
