ALP121-S00
Corporation for the CENTUM VP DCS platform. It functions as a PROFIBUS‑DP master, enabling high‑speed data exchange between the DCS and PROFIBUS‑DP slave devices such as PLCs, motor drives, remote I/O, and PROFIBUS‑PA devices (via DP/PA couplers). The module supports isolated RS‑485 communication and can be installed on AFV30/AFV40 field control stations, ANB10 ESB bus node units, or ANB11 optical ESB bus node units, making it suitable for process industries including chemical, power, oil and gas, and metallurgy.
