Cable Specifications
Basically, cables (2 cores) that withstand temperatures of at least 80°C are used for this wiring.
When the ambient temperature of the detector exceeds 75°C, install a terminal box, and connect
to the detector using six-piece 600 V silicon rubber insulated glass braided wires.
5.2.5 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 Ω of
loop resistance or less. Keep detector wiring away from power wiring.
