More Information

Overview Manuals Specifications Current Output Performance Diagnostics

Features:

  • Controls eight current-loop outputs from one external supply
  • Offers configurable zero or hold-last-state output defaults
  • Returns optional module and channel diagnostics to the BIU
IC670ALG330 can exchange up to eight analog output words, four bytes of diagnostic input data, and two bytes of fault-clearing output data with its Bus Interface Unit.

Channel activation controls both the physical output and alarm updates: an inactive IC670ALG330 channel goes to 0 mA, while existing diagnostic bits remain available to be cleared.

The available load is not a single fixed value across all conditions. Compare supply voltage, ambient temperature, and required loop resistance with the published derating information.

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.

Loop Command Structure:

  • Channel count: Eight single-ended outputs share the module external power source.
  • Command range: Normal operation covers 0 to 20 mA with additional overrange to about 20.48 mA.
  • Load envelope: User load may reach 1250 Ω only when supply voltage and thermal conditions permit.
  • Individual setup: Scaling, channel activation, and local default behavior are configurable per output.

Current Conversion Characteristics:

  • Converter resolution: The analog output path is specified at 16 bits with 14-bit magnitude data.
  • Current increment: Maximum-resolution operation corresponds to 0.3125 µA per count.
  • Output refresh: A channel updates in approximately 1.5 ms under normal operation.
  • Rated accuracy: Typical accuracy at 25°C is 0.05%, with a 0.1% maximum specification.

Stored Fault Information:

  • Module status: Diagnostic bits identify calibration, command, BIU timeout, and missing user-supply conditions.
  • Range alarms: Separate status bits report under- and overrange states for each output channel.
  • Loop continuity: Open-wire bits are available for all eight current outputs.
  • Clearing method: Optional discrete output commands clear stored alarm and diagnostic bits after the cause is corrected.
Description
The eight single-ended outputs of IC670ALG330 share an external supply and deliver commanded current from 0 to 20 mA, with overrange available to approximately 20.48 mA. Individual channels can be activated, scaled, and assigned output behavior independently.

If communication or backplane power is lost while user power remains present, IC670ALG330 can set its outputs to zero or hold their last values according to configuration. The hold-last-state path retains an output until new BIU data arrives or the field supply is removed.

Diagnostic data from IC670ALG330 covers supply, calibration, BIU timeout, range, and open-wire conditions. Load impedance must be checked against field-supply voltage and ambient temperature, and BIU revision 2.0 or later is required.

Technical notes
IC670ALG330 provides eight current-source outputs with 16-bit conversion, configurable scaling, and open-wire alarm reporting.

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 happens when a channel on IC670ALG330 is configured inactive?
An inactive channel on IC670ALG330 is driven to 0 mA and stops updating its optional alarm data.
Which current range and overrange apply to IC670ALG330?
IC670ALG330 provides 0 to 20 mA commanded output and supports overrange to approximately 20.48 mA.
Can IC670ALG330 maintain outputs after loss of BIU data?
Yes. IC670ALG330 can hold the last output value when configured to do so and when the user supply remains present.
How does load impedance affect IC670ALG330 operation?
IC670ALG330 permits up to 1250 Ω, but the acceptable load depends on supply voltage and temperature and must follow the manual derating curves.
Which faults can IC670ALG330 report to the BIU?
IC670ALG330 can report user-supply, calibration, BIU timeout, command, underrange, overrange, and open-wire conditions.
What external power is specified for IC670ALG330?
IC670ALG330 requires an 18 to 30 VDC external output supply in addition to power drawn from the BIU.
Which revision and replacement checks apply to IC670ALG330?
IC670ALG330 requires BIU revision 2.0 or later; replacement checks should include the full catalog number, load, field supply, defaults, scale, terminal wiring, and active-channel setup.
