Process Signal Wiring Standard
Process Signal Wiring Standard
(OP)
Does anyone know if there is a published standard that provides guidelines for routing process signal wires (4-20mA)? This would be as opposed to power wiring (e.g. route signal wire in separate conduit, separated by a distance...). Thanks.

What Voltage power, 120 VAC, 4160 VAC?
Constant Voltage power or 120 VAC control switching circuits?
Buried, pole lines or in tray?
Shielded or non-shielded 4-20 mA pairs with overall shielded cable, ...?
Cross perpendicular and separate power and mA by at least six inches. Use fiber optics.
