The ABB REF615C_C HCFFAEAGANB2BAN1XC is a terminal board used in the ABB Ability™ System 800xA® Select I/O system. It is designed as an interface component that provides field wiring termination and connection between field devices and Select I/O electronic modules. The TB867 belongs to ABB’s modular I/O infrastructure, supporting flexible, scalable, and service-friendly automation installations.

Unlike traditional I/O modules that combine electronics and field terminals in one unit, the Select I/O architecture separates the I/O electronics from the termination area. The TB867 provides a convenient termination point, allowing maintenance or module replacement without disturbing field wiring.
