Wiring inputs and outputs

The Tracer MP581 enclosure is designed to simplify the wiring and con-
figuration of inputs and outputs by providing a large space for routing
wires and by eliminating the need to manipulate jumpers. Table 16 lists
Tracer MP581 inputs and outputs.

Input/output wiring guidelines

Input/output wiring must meet the following guidelines:
Wiring must conform with the National Electrical Code and local elec-
•
trical codes.
Use only 18 AWG twisted-pair wire with stranded, tinned-copper con-
•
ductors.
Binary input/output wires must not exceed 1,000 ft (300 m).
•
Analog input wires must not exceed 300 ft (100 m) for thermistors
•
and 0–10 Vdc inputs and 1,000 ft (300 m) for 0–20 mA inputs.
Analog output wires must not exceed 1,000 ft (300 m) for 0–10 Vdc
•
outputs and 0–20 mA outputs.
Do not run input/output wires in the same wire bundle with high-
•
voltage power wires. Running input/output wires with 24 Vac power
wires is acceptable, but the input wire must be shielded.
Terminate input/output wires before installing the main circuit board
•
(see "Installing the circuit board" on page 76).
