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.
Control Wire Types
Table 1.G Recommended Control and Signal Wire (1)
I/O Terminal Block
Table 1.H I/O Terminal Block Specifications
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.
I/O Wiring Recommendations
!
ATTENTION: Driving the 4-20mA analog input from a voltage
source could cause component damage. Verify proper configuration
prior to applying input signals.
