Pepperl+Fuchs HiCTB16-YC3-RRB-AK-CC-DX32 H-System Termination Board

The Pepperl+Fuchs HiCTB16-YC3-RRB-AK-CC-DX32 is an H-System termination board specially designed for Yokogawa CENTUM VP DCS systems. It matches the 32-channel ADV151 digital input card and supports up to 16 isolated barrier modules to realize intrinsic safety signal isolation between hazardous field areas and safe control rooms.

This termination board adopts 24 VDC power supply, built-in reverse polarity protection and 4A fusing. It uses spring terminals for field wiring and a 50-pin system connector for DCS connection, widely stocked as spare parts for petrochemical and chemical explosion-proof control cabinet maintenance and renovation.
