Input/output terminal wiring

All input/output terminal wiring for the EX2 module must meet the fol-
lowing requirements:
All wiring must be in accordance with the National Electrical Code
•
and local codes.
Use only 18–22 AWG, stranded, tinned-copper, shielded, twisted-pair
•
wire.
• Binary output wiring must not exceed 1,000 ft (300 m).
Binary input and 4–20 mA input wiring must not exceed 1,000 ft
•
(300 m).
Thermistor input, RTD input, and 0–10 Vdc input wiring must not
•
exceed 300 ft (100 m).
• Analog and 24 Vdc output wiring distances depend on the specifica-
tions of the receiving unit. Use shielding for analog and 24 Vdc
outputs.
Do not run input/output wires in the same wire bundle with ac-power
•
wires.
The EX2 module has four binary outputs, four analog outputs, and six
universal inputs.
