I/O wiring recommendations
Important points to remember about I/O wiring:
•
Always use copper wire.
•
Wire with an insulation rating of 600V or greater is recommended.
•
Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot).
Important: I/O terminals labeled “Common” are not referenced to the safety ground (PE) terminal and
are designed to greatly reduce common mode interference.
ATTENTION: Driving the 4-20mA analog input from a voltage source could cause
component damage.
Verify proper configuration prior to applying input signals.
Control wire types
Table 1.G Recommended control and signal wire*
Wire type(s) Description Minimum insulation rating
Shielded wire
0.8 mm
2
(18 AWG), twisted pair, 100%
shield with drain.
300V
60°C (140°F)
0.8 mm
2
(18 AWG), 3 conductor, shielded
for remote pot only.
*
If the wires are short and contained within a cabinet which has no sensitive circuits, the use of shielded wire may not be
necessary, but is always recommended.
I/O terminal block
Table 1.H Terminal Block specifications*
Maximum wire size* Minimum wire size* Torque
1.3 mm
2
(16 AWG) 0.2 mm
2
(24 AWG) 0.5-0.8 N-m (4.4-7 lb.-in.)
*
Maximum/minimum sizes that the terminal block will accept - these are not recommendations.
Maximum control wire recommendations
Do not exceed control wiring length of 30 meters (100 feet). Control signal cable length is highly
dependent on electrical environment and installation practices.
To improve noise immunity, the I/O terminal block Common must be connected to ground
terminal/protective earth.
If using the RS485 (DSI) port, I/O Terminal 16 should also be connected to ground terminal/protective
earth.
