More Information

Overview Manuals Output Circuits Diagnostics Bus Redundancy Power & Loads

Features:

  • Provides six current-source analog outputs in one Genius I/O block.
  • Supports 4–20 mA on every output and voltage use on outputs five and six.
  • Reports underrange, overrange, and feedback errors by channel.
General Electric IC660BBA105 combines bus communication, loop power, conversion, and diagnostics inside a field-mounted block.

Output scaling and feedback checks are configured through Genius I/O rather than adjusted as separate external circuits.

The block's supply is isolated from the bus logic, separating the field-output path from controller communication.

The General Electric IC660BBA105 115 VAC/125 VDC Current-source Analog Output Block may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Six analog output paths

  • Current channels: All six outputs support 4–20 mA loops.
  • Voltage option: Outputs five and six can be configured for supported voltage ranges.
  • Loop power: The block supplies power to each output circuit.
  • Update path: Commands from the Genius bus refresh the outputs every 25 ms.

Per-channel supervision

  • Underrange: A low output condition can be reported to the controller.
  • Overrange: The block detects an output beyond its configured range.
  • Feedback error: Output feedback is compared with the commanded result.
  • Hold state: The configured last-state behavior applies during a communication interruption.

Genius bus arrangement

  • Bus interface: The block exchanges output commands and diagnostics over Genius I/O.
  • BSM control: A dedicated output can drive an IC660BSM012 Bus Switching Module.
  • Redundant bus: The BSM selects the available bus path in a redundant installation.
  • Configuration: Scaling, fault reporting, and feedback timing are stored with the block setup.

Supply and field limits

  • AC source: The documented supply range is 98–132 VAC at 47–63 Hz.
  • DC source: The block also accepts 105–145 V DC.
  • Current load: A current output supports loads from zero to 850 ohms.
  • Isolation: The block withstands 1,500 V between blocks for one minute.
Description
General Electric IC660BBA105 is a Genius I/O current-source analog output block with six control-loop outputs. The block receives output commands over the Genius bus and converts them into current signals for connected field devices.

All six channels on General Electric IC660BBA105 support 4–20 mA operation, while channels five and six can also be configured for voltage output. Each channel provides its own loop power and control, so no separate field supply is required for the standard current-loop connection.

Configuration data in General Electric IC660BBA105 links engineering-unit scaling, hold-last-state behavior, and output feedback checks to each circuit. Underrange, overrange, and feedback-error diagnostics allow the controller to distinguish a commanded value from an abnormal loop condition.

The 115 VAC or 125 V DC block supply powers the General Electric IC660BBA105 electronics and its output circuits. A dedicated output can control a Bus Switching Module, allowing the analog block to participate in a redundant Genius-bus 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.
How are the six outputs of General Electric IC660BBA105 used?
Every channel can drive a 4–20 mA loop, and channels five and six can instead be configured for supported voltage-output applications.
Does General Electric IC660BBA105 require separate loop power?
No separate loop supply is required for the documented current-source connection because the block powers and controls each output circuit.
Which conditions does General Electric IC660BBA105 diagnose?
The block can report output underrange, overrange, and feedback errors so the controller can identify abnormal loop behavior.
How does scaling work on General Electric IC660BBA105?
Configuration maps the output command to engineering units and can also define feedback timing and the state retained during a communication interruption.
Can General Electric IC660BBA105 be used on a redundant Genius bus?
Yes. Its dedicated BSM control output can operate the specified Bus Switching Module when the system is wired for redundancy.
Why can the lower-voltage Genius variant not directly replace General Electric IC660BBA105?
General Electric IC660BBA105 requires a 98–132 VAC or 105–145 V DC source, whereas the IC660BBA025 uses a different 24/48 V DC supply range.
