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).

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.
