Important Application Note
CRBX01 is a communication/bus extension module, not a conventional I/O module. It is used in pairs to create a redundant fiber-optic remote link. ABB’s current documentation states that each remote link can support up to 60 HN800 devices, with up to 8 remote links per controller and a maximum link distance of 3.0 km using 62.5/125 µm multimode fiber.
Replacement note: No separate replacement model is specified. ABB’s current documentation continues to list the cRBX01 as an active component within the Symphony Plus SD Series remote I/O architecture.
