Cable Connections
Listed below is information on making connections to the
SIMEAS P, as well as examples of suitable cable types.
•
Measured quantity input connections (voltage, current):
Wire size:
#12-22 AWG Cu
Min. cable voltage rating min. 600 V AC
Solid or stranded with connector sleeve
Torque rating:
9 in-lb. max.
•
Power supply, PG, output contact connections and
I/O module contacts:
Wire size:
#12-22 AWG Cu
Min. cable voltage rating min. 300 V ac
Solid or stranded with connector sleeve
Torque rating:
7 in-lb. max.
The maximum allowable device operating current is
0.5 A. To ensure proper selectivity in the fusing
sequence, the power supply line is to be equipped with
a minimum 2A circuit breaker (the maximum value
depends on the wiring of the cabinet). The circuit
breaker must be installed close to the device.
The switch must be marked as "switch for SIMEAS P"
and must comply with IEC60947-1 and IEC60947-3.
•
The protective ground is at least the same gauge size
as the power supply wire.
•
Connection to communication interface:
Standard PROFIBUS cable type A
Two-wire or four-wire, twisted and shielded
•
For analog inputs and outputs you have to use shielded
cables with the shield connected to ground.
