5.2 Wiring for Detector Output

This wiring enables the converter to receive cell output from the detector, output from a

thermocouple and a reference junction compensation signal. Install wires that allow for

10 V of loop resistance or less. Keep detector signal wiring away from power wiring.

Separate the signal and the power wiring.

CAUTION

If shielded cables cannot be used between the detector and the terminal box, for ex-

ample, when heat-resistant wiring is used, locate the detector and the terminal box as

close together as possible.

5.2.1 Cable Specifications

Basically, PVC sheathed PVC insulated cable (six core) is used for this wiring. When

the ambient temperature of the detector exceeds 80°C, install a terminal box, and

connect with the detector using six-piece 600-V silicon rubber insulated glass braided

wire.
