FAQs

Q: Can this board handle both voltage and current signals?
A: Yes, it supports standard 0–10 V voltage and 4–20 mA current inputs.

Q: How many channels are available?
A: The board is configurable for 8 or 16 analog input channels.

Q: Is it compatible with other ABB control systems?
A: It is specifically designed for MasterPiece 200/200/1 controllers and may not be compatible with newer ABB platforms.

Q: What makes it different from DSRF-series frames?
A: Unlike DSRF subrack frames, the DSTA121 functions as an active analog input board, processing field signals rather than providing structural housing.
