More Information

Overview Manuals Current Range Default Matrix Loop Capacity Applications

Features:

  • Eight current-sourcing analog outputs
  • Hardware selection for 4–20 mA or 0–20 mA
  • CPU/NIU-specific low-end response documented by event
The General Electric IC200ALG326 model number designates the eight-point current-output module in the VersaMax analog family.

Separate range and hold links define how controller counts become loop current and what each channel does after a stop or supply interruption.

Field-supply voltage, total loop resistance, grouped returns and the host-specific default table are verified together before the output bank is placed in service.

The General Electric IC200ALG326 Current Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
General Electric IC200ALG326 Current Output Module Manuals,Datasheets,Link 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.

JMP1 and Loop Scaling

  • Default span: The open range-jumper state maps controller data to 4–20 mA.
  • True-zero span: Installing JMP1 changes the complete module to 0–20 mA.
  • Project agreement: The host configuration is updated whenever the physical range link changes.
  • Step size: A 2.5 µA increment represents five counts in live-zero mode and four counts in true-zero mode.

Host and Event Dependence

  • Hold selection: An open JMP2 path preserves the last current command for supported interruption cases.
  • Low-end selection: Installing JMP2 requests the bottom of the configured 0–20 or 4–20 mA span.
  • CPU behavior: A stopped CPU can produce 0 mA in the 4–20 mA range even with low-end default selected.
  • NIU behavior: Loss of communications can leave an NIU-controlled 4–20 mA channel at 4 mA.
  • Field-power loss: Removing the external source drives the output to 0 mA regardless of jumper intent.
  • Table lookup: Final behavior is taken from the manual matrix for the exact host, range, jumper and event combination.

Supply Headroom and Load Check

  • Voltage source: The eight output circuits operate from an external +18 to +30 VDC field supply.
  • Resistance budget: Maximum loop resistance is calculated from field voltage and the 20.38 mA overrange value.
  • Dynamic limits: The connected load stays within the published capacitance and inductance boundaries.
  • Current demand: Supply sizing includes inrush and the all-channels-at-full-scale operating value.

Eight-Loop Process Commands

  • Live-zero actuators: Eight compatible valve or drive inputs can use 4–20 mA with a defined underrange region.
  • True-zero receivers: JMP1 adapts the complete bank for devices that interpret 0 mA as a valid command.
  • Distributed outputs: NIU placement moves the current-source channels closer to field loads while retaining host-aware default behavior.
  • Loop diagnostics: Field-power status and calculated load headroom support systematic troubleshooting of weak output current.
Description
Current-driving loads are served by eight sourcing outputs in the General Electric IC200ALG326. The default 4–20 mA range includes modest overrange to approximately 20.38 mA, while a field-terminal jumper changes the complete bank to 0–20 mA.

Loss behavior for General Electric IC200ALG326 depends on a second carrier link and the host arrangement. Outputs either retain their last state or move to the low end of the selected range; the manual's state table shows that the resulting 0 mA or 4 mA value can differ between CPU and NIU stations.

An external +18 to +30 VDC source energizes the field side of General Electric IC200ALG326, with published current limits for inrush, no-load use and all eight channels at full scale. Load resistance follows the available field voltage, and shielded pairs return through the grouped terminals shown for the carrier.

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 IC200ALG326 deliver 0 mA instead of 4 mA after a fault?
General Electric IC200ALG326 follows a state table that depends on selected range, hold/default jumper, event type and whether a CPU or NIU controls the rack. Check those four conditions before interpreting 0 mA as an incorrect setting.
How is the 0–20 mA range selected on General Electric IC200ALG326?
General Electric IC200ALG326 uses the field-terminal range jumper: no link selects 4–20 mA and JMP1 selects 0–20 mA. Remove field and backplane power first, then update the hardware configuration to match.
What limits the maximum load resistance for General Electric IC200ALG326?
General Electric IC200ALG326 bases the resistive-load ceiling on field-supply voltage using the manual's RL(max) relationship, with 800 Ω as the published maximum. Include wiring resistance and the receiving device in the calculation.
A channel on General Electric IC200ALG326 will not reach 20 mA; what measurements help isolate the cause?
General Electric IC200ALG326 needs adequate external field voltage at B18–B17 under load. Measure that supply, total loop resistance and commanded counts, then inspect the FLD PWR state before replacing the module.
Can General Electric IC200ALG326 hold output current when backplane power disappears?
General Electric IC200ALG326 can retain the last state with the hold jumper open, provided the external field supply remains available. The manual's CPU/NIU table should be checked for the exact loss event and configured range.
Where do negative controller commands go on General Electric IC200ALG326?
General Electric IC200ALG326 converts negative values to 0 mA in a VersaMax CPU rack. Under NIU control, negative commands go to the low end of the selected range, so application logic must account for the host type.
