More Information

Overview Manuals Assembly Match Loop Wiring Configuration Application
  • 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.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • 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
Description
IC660BBA026 is a GE Fanuc Genius I/O current-source analog input block powered from a 24/48 V DC source.

It accepts six isolated 4–20 mA input loops, supplies excitation for field transmitters, converts each signal to engineering data, and reports configurable input diagnostics.

Before replacement, confirm Phase B hardware, bus compatibility, terminal and electronics assemblies, device number, baud rate, input scaling, alarms, redundancy settings, and saved configuration.

Technical notes
IC660BBA026 requires Phase B compatibility, 24/48 V DC block power, correct TBA026/EBA026 assemblies, Genius address and baud settings, channel configuration, and BSM021 selection; confusing BBA106 can damage the installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the practical difference between GE IC660BBA026 and IC660BBA106?
Both are six-input current-source analog blocks, but IC660BBA026 uses 24/48 V DC block power while IC660BBA106 uses 115 V AC/125 V DC; they are not power-compatible substitutes.
Which removable assemblies belong to GE IC660BBA026?
GE documentation identifies IC660TBA026 as the terminal assembly and IC660EBA026 as the electronics assembly; match both labels before combining or replacing parts.
What should be saved before replacing GE IC660BBA026?
Save the Genius device number, baud rate, channel scaling, alarm limits, conversion times, fault reporting, CPU redundancy, BSM control, and the controller configuration.
Can GE IC660BBA026 be used on a redundant Genius bus?
Yes, when the documented IC660BSM021 24/48 V DC Bus Switching Module, wiring, block configuration, and controller redundancy design are present.
How should an open-wire alarm from GE IC660BBA026 be investigated?
Check transmitter power, loop polarity, excitation output, field wiring continuity, terminal seating, loop current, scaling, and the configured diagnostic threshold before replacing the block.
Why does the Phase B identity matter for GE IC660BBA026?
The GE manual lists IC660BBA026 as a Phase B product without a Phase A equivalent; confirm host controller, software, and hand-held-monitor compatibility with the actual hardware revision.
What is the main selection risk for GE IC660BBA026?
The main risk is confusing it with the 115 V IC660BBA106 or mixing incorrect terminal/electronics assemblies, power source, and saved block configuration.
