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 4 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 18–22 AWG (1.02–0.643 mm
2
), twisted-pair wire with
stranded, tinned-copper conductors.
• 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 Chapter 8, “Installing the circuit board”).
