- Connects six isolated 4–20 mA current loops to a Genius I/O bus
- Provides individual transmitter excitation and configurable signal conversion
- Reports open-wire, alarm, overrange, and underrange conditions
IC660BBA026 is the 24/48 V DC member of GE's six-input current-source analog block pair.
Each channel supplies a field loop, converts current to controller data, and supports configuration of scaling, conversion time, alarms, fault reporting, and redundancy behavior.
Correct replacement requires Phase B system compatibility, the proper terminal and electronics assemblies, 24/48 V DC power, Genius network settings, and the saved block configuration.
Availability, condition, price, and shipping time for IC660BBA026 are confirmed during quotation.

- Confirm IC660TBA026 terminal and IC660EBA026 electronics assembly identities
- Check Phase B controller, software, and hand-held-monitor compatibility
- Do not interchange the block with the differently powered IC660BBA106
- Verify 24/48 V DC block power, polarity, grounding, and enclosure practice
- Land each transmitter loop on its documented excitation, input, common, and ground terminals
- Use IC660BSM021 only where the approved redundant-bus design requires it
- Restore device number, baud rate, reference address, and report-fault settings
- Reapply channel scaling, conversion time, alarms, and active-state selections
- Validate input current and controller engineering values channel by channel
- Remote acquisition of six isolated 4–20 mA process transmitters
- Genius I/O analog input on 24/48 V DC powered stations
- Redundant Genius bus analog measurement using the documented BSM arrangement
