Features:
- CS31 remote digital I/O module operating at 24 V DC.
- Sixteen fixed inputs, eight transistor outputs and eight configurable channels.
- ABB documents 07DC91-AD as the replacement path.
The module exchanges binary field states with an installed CS31 control system.
Configurable channels derive their behavior from both wiring and the user program.
Migration review must preserve bus, terminal and logic relationships rather than only the channel count.
Apter Power supports exact-part quotation, technical-document requests and CS31 migration matching for ABB 07DC91 GJR5251400R0202.
