More Information

Overview Manuals Range Jumper Signal Quality System Fit Applications

Features:

  • Eight differential current-input pairs
  • Module-wide hardware selection for 4–20 mA or 0–20 mA
  • One analog data word returned for each channel
The General Electric IC200ALG262 catalog number denotes the eight-channel differential-current member of the VersaMax analog input range.

Paired conductors allow the module to reject voltage common to both input leads while reporting the measured loop current to the CPU or NIU.

The selected jumper state, controller scaling and transmitter supply must describe the same installation. Differential measurement does not provide channel-to-channel isolation, so the grounding plan still covers the complete input group.

The General Electric IC200ALG262 Current Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Carrier Link and Data Scaling

  • Open link: Leaving A18 and A17 unconnected selects the 4–20 mA live-zero range for all eight channels.
  • Closed link: Joining A18 to A17 selects 0–20 mA operation across the complete input group.
  • Range scope: The jumper changes the module as a whole and does not assign different spans to individual channels.
  • Controller conversion: Raw-count scaling follows the chosen range, including the manual's separate formulas for 4–20 mA and 0–20 mA.

Differential Reference Control

  • Common-mode window: Both conductors of every source remain within –10 to +10 V relative to module common.
  • Interference rejection: The differential inputs reject voltage shared by the two leads instead of treating it as loop current.
  • Group relationship: All eight channels belong to one input group and have no channel-to-channel isolation.
  • Shield termination: The cable shield connects by the method specified for the selected VersaMax carrier.

Power, Status and Host Exchange

  • Data map: The VersaMax CPU or NIU receives one analog input word for each of the eight physical channels.
  • Module power: Conversion electronics draw their operating supply from the VersaMax backplane.
  • Transmitter power: Connected field devices require a separate external source because the module does not energize their loops.
  • OK indication: The green OK LED requires backplane power, internal field power, valid configuration and host recognition.
  • Open-wire scope: Broken-loop reporting is available in the 4–20 mA range but not when zero current is a valid 0–20 mA reading.

Eight-Loop Differential Acquisition

  • Paired loop sources: Eight current transmitters can be measured through dedicated differential conductor pairs.
  • Live-zero supervision: The default 4–20 mA selection lets application logic distinguish a broken loop from a normal low measurement.
  • Distributed station: Placement through a VersaMax NIU keeps the input pairs near field wiring and delivers eight ordered data words to the controller.
Description
The General Electric IC200ALG262 provides eight differential current inputs and eight analog words for a VersaMax CPU or NIU. A carrier jumper selects one range for the complete module: no jumper for 4–20 mA or an A18-to-A17 link for 0–20 mA.

Differential pairs on General Electric IC200ALG262 operate within a documented ±10 V common-mode window and provide 70 dB common-mode rejection. The channels form one group without channel-to-channel isolation, so field wiring and shield termination must maintain a suitable shared reference.

Backplane power runs General Electric IC200ALG262, while external power is required for field transmitters. Open-wire reporting applies only to 4–20 mA operation, and controller scaling must match the physical jumper selection.

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 General Electric IC200ALG262 not report an open wire in 0–20 mA mode?
General Electric IC200ALG262 provides open-wire diagnostics in 4–20 mA operation. When the jumper selects 0–20 mA, zero current can be a valid measurement, so use application logic and wiring checks appropriate to the configured range.
Why do all channels on General Electric IC200ALG262 show the wrong scale after installation?
General Electric IC200ALG262 uses a module range jumper rather than independent software ranges. Verify whether A18 and A17 are jumpered for 0–20 mA and make the CPU or NIU scaling match that physical selection.
Why is General Electric IC200ALG262 energized but the field transmitters remain off?
General Electric IC200ALG262 receives its own operating power from the VersaMax backplane, but it does not provide transmitter loop power. Check the external field source, loop polarity and return wiring for every connected instrument.
How can noisy readings on General Electric IC200ALG262 be investigated?
For General Electric IC200ALG262, route shielded signal cable away from switching conductors, ground shields as shown in the VersaMax manual and check that common-mode voltage remains within the documented range before applying software filtering.
What should be checked when General Electric IC200ALG262 data is clipped near full scale?
General Electric IC200ALG262 uses different count scaling and clipping thresholds for 4–20 mA and 0–20 mA operation. Confirm the jumper, engineering-unit conversion and actual loop current before treating the result as a module fault.
Can General Electric IC200ALG262 replace an isolated-channel input without wiring review?
General Electric IC200ALG262 isolates the input group from logic and frame but does not provide channel-to-channel isolation. Review field references, grounding and common-mode conditions before replacing a module that isolated every channel.
