Ovento Systems carries the Allen-Bradley 1756-DHRIO as used and refurbished stock within our i/o & communication modules range, sourced through equipment liquidations, service company fleet upgrades and OEM trade-ins across North America and Asia.
Modules are seated in a live chassis and exercised channel by channel, communication modules are checked for connection count and port function, and any missing terminal blocks or keying are stated in the listing. Everything is tested before it is listed and ships from our Plano, TX facility, usually same day. We supply this model most often to maintenance departments holding critical spares, panel builders and system integrators. Tell us the quantity and the delivery date you are working to and we will confirm both.
