More Information

Overview Manuals Compatibility Environment Monitoring Calibration

Features:

  • IC600BF942 delivers four independently addressed -10 to +10 V outputs.
  • Twelve-bit conversion provides one-part-in-4096 resolution.
  • Revision B works in local or remote Series Six I/O racks.
IC600BF942 maps its four channels through 16 consecutive output references and updates the channel selected by the two-bit address field.

A BOARD OK indicator reports module access and controller or rack conditions without duplicating the individual voltage command.

Channel jumpers permit range assignment, while separate offset and gain adjustments support calibration at the installed operating temperature.

Rack and revision fit for bipolar output service

  • Platform: Install IC600BF942 in a Series Six I/O rack or the I/O section of a compatible CPU rack.
  • Series A: Use revision A only for local I/O applications.
  • Series B: Revision B supports both local and remote I/O locations.
  • CPU level: Confirm the documented minimum CPU serial level before placing the analog module in service.

Conditions for stable bipolar conversion

  • Operating range: Maintain 0 to 60 degrees C at the outside of the rack.
  • Storage range: The documented storage limits are -20 to 80 degrees C.
  • Humidity: Keep relative humidity between 5 and 95% without condensation.
  • Rack demand: Reserve 1.5 A from the 5 VDC I/O-rack supply.

Following channel data and module health

  • BOARD OK: The faceplate LED shows whether IC600BF942 is operating and being accessed.
  • Channel code: Output bits 13 and 14 identify which of the four channels receives new data.
  • Held value: An unselected channel maintains its last converted voltage.
  • Fault context: A stopped CPU, rack-supply problem, or board malfunction can remove the BOARD OK indication.

Restoring -10 to +10 V channel accuracy

  • Interval: Calibrate IC600BF942 every 90 days for maximum accuracy.
  • Equipment: Use a five-digit voltmeter and IC600MA508A calibration connector.
  • Low end: Apply the documented channel code with data 800 hex and adjust to -10.0000 V.
  • High end: Apply data 7FF hex and adjust the selected channel toward +9.9951 V.
Description
The General Electric IC600BF942 four-channel bipolar analog output module supplies isolated -10 to +10 VDC commands for Series Six process-control and motor-speed reference circuits.

For each selected channel, IC600BF942 converts twelve binary data bits at one-part-in-4096 resolution and holds the resulting level until the CPU writes that channel again.

An optically coupled data path separates IC600BF942 user-side voltage circuitry from the I/O bus. The four single-ended outputs share a common reference and can feed differential or single-ended receivers.

Revision and calibration details matter when applying IC600BF942 in an existing rack: Series A is limited to local I/O, Series B supports local or remote I/O, and the manufacturer specifies periodic channel calibration.

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.
Why does an IC600BF942 channel retain its previous command between CPU writes?
IC600BF942 stores the converted value for each selected channel and maintains that bipolar voltage until the CPU addresses and updates the channel again.
How is a channel selected when writing data to IC600BF942?
IC600BF942 uses output-status bits 13 and 14 as a two-bit channel code, while bits 1 through 12 carry the straight-binary voltage command.
Which IC600BF942 revision is suitable for a remote I/O rack?
IC600BF942B is documented for local and remote I/O; IC600BF942A should remain in a local I/O application.
What should be checked if an IC600BF942 receiver reads the wrong reference level?
IC600BF942 uses a shared user-side common, so receiver reference points should be tied together and kept at the same potential.
Can IC600BF942 tolerate an accidental output short circuit?
IC600BF942 is specified to sustain a continuous short circuit on all outputs, but the field wiring and rack condition should still be corrected before operation resumes.
What can turn the BOARD OK indicator off on IC600BF942?
IC600BF942 removes the BOARD OK indication for a board fault, rack-power problem, stopped or Run Disabled CPU, or lack of module access after those conditions clear.
How is periodic accuracy restored for IC600BF942?
IC600BF942 is calibrated channel by channel at normal operating ambient with a five-digit voltmeter and IC600MA508A calibration connector, on the manufacturer's 90-day interval.
