Condition

AS STATED BY SELLERS

New	1
Not stated	2

Most industrial listings do not state condition — treat unstated as unknown, not as new. Across 38 comparable parts in ControlLogix 1756, used and refurbished units list at 104% of new — condition is not a reliable discount signal for industrial parts, because refurbished stock from trade houses carries warranty and test reports.
