More Information

Overview Manuals Specifications Loop Integrity Filter Tuning Product Applications

Features:

  • Two-loop acquisition: independent configuration for two current signals
  • Current ranges: 0...20 mA and 4...20 mA support
  • Diagnostic data: high/low alarms plus overrange and underrange status
1734-IE2C provides a compact two-loop current-input path with detailed per-channel configuration.

The notch frequency trades response speed against noise rejection, so it should be chosen from the real process and interference environment.

A durable service baseline records measured loop current, raw count, scaling, alarms, and return-path wiring for both channels.

Availability of 1734-IE2C is subject to Apter Power inventory and sourcing confirmation.

Separate process and circuit faults

  • Live zero: use 4...20 mA where the transmitter design requires fault visibility.
  • Loop power: measure supply and current at the terminal base.
  • Common: review non-isolated channel reference paths.
  • Status: interpret under/overrange before changing scaling.

Choose the two-channel response

  • Interference: identify mains or process noise frequency.
  • Notch: select the supported setting that meets response needs.
  • Scaling: retain signed-integer and engineering-unit mapping.
  • Verification: compare both channels with a calibrated source.

Supported product applications

  • Two-wire transmitters: acquire documented 4...20 mA process loops.
  • Current sensors: read 0...20 mA devices where live-zero detection is not required.
  • Machine skids: combine two analog feedback points in one remote slot.
  • Maintenance spares: replace a validated two-channel current-input position.
Description
1734-IE2C acquires two single-ended, non-isolated current loops in the POINT I/O family. The Series C module supports 0...20 mA and 4...20 mA ranges with 16-bit conversion across 0...21 mA and signed-integer data for the controller.

With per-channel notch filtering, scaling, alarm limits, and overrange or underrange status, 1734-IE2C can separate a process excursion from a loop or wiring problem. Its two-channel format suits applications where traceable loop-by-loop service is more important than maximum density.

Engineering a 1734-IE2C installation requires the correct terminal base, loop-power plan, common reference, shield path, range, filter, and controller profile. Replacement records should retain raw current and engineering-unit checks rather than relying on a copied analog-module template.

Technical notes
Use 1734-IE2C only after confirming the two current-loop references and the intended 0...20 mA or 4...20 mA ranges. Match Series C, terminal-base wiring, loop power, shield termination, notch filter, signed-integer scaling, alarm limits, update requirement, and overrange diagnostics; then inject known current to verify both controller channels.

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 can 1734-IE2C distinguish a low process value from a broken 4...20 mA loop?
Review raw current and underrange status, then measure loop supply and terminal current before deciding whether the transmitter or process is responsible.
Why does changing the notch filter on 1734-IE2C alter response time?
Higher noise rejection uses a different conversion timing, so validate the selected filter against both interference and the process change rate.
What causes both 1734-IE2C channels to drift together?
Investigate shared common potential, loop-supply stability, grounding, shield termination, cabinet temperature, and controller scaling before calibrating individual transmitters.
Can 1734-IE2C accept a voltage transmitter by changing software range?
No. It is a current-input catalog; use the correct voltage-input module or a manufacturer-approved conversion that respects every electrical limit.
Which data should be captured when commissioning 1734-IE2C?
Record range, notch, raw counts, engineering units, alarm thresholds, injected current, loop supply, terminal assignments, and status for both channels.
What should be included in a 1734-IE2C spare-module request?
Provide the Series, terminal base, two-loop ranges, controller project, quantity, condition, label photos, destination, and required delivery date.
