Features:
- Fifteen single-ended –10 to +10 V analog inputs
- Enhanced ±30 V input fault withstand
- Internal A/D path testing with a defined stop-scan response
The
General Electric IC200ALG265 catalog number identifies the enhanced-protection version of the 15-channel VersaMax voltage input module.
One carrier position converts a common-return group into fifteen ordered input words while the internal test circuit monitors the A/D path.
System design covers the shared A17 reference, external power for field transceivers, carrier-specific shield grounding and the selected response to lost module data.
The General Electric IC200ALG265 Voltage Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Known-Stimulus A/D Monitoring
- Reference check: The module applies a known internal signal to verify the A/D conversion path.
- Three-event rule: Scanning stops only after three consecutive test results differ from the expected value.
- Local warning: The OK indicator turns off when the conversion test produces an Internal Hardware fault.
- Recovery decision: A power cycle clears the reported state, while a recurring fault points to module replacement.
Reference and Shield Arrangement
- Common node: A17 carries the return for all fifteen single-ended voltage inputs.
- Extra terminations: An auxiliary strip or shorting bar can provide convenient connection points for multiple return conductors.
- Isolation boundary: The complete input group is isolated from logic and frame, but individual channels are not isolated from one another.
- Shield path: Grounding follows the terminal, compact or connector-style carrier used in the station.
- Source supply: Field transceivers receive power externally rather than from the analog input module.
Count Mapping and Loss Handling
- Word order: The CPU or NIU receives one signed analog word for each physical input.
- Voltage conversion: The published relationship uses 32,000 counts for 10 V across the bipolar span.
- Fallback choice: Configuration determines whether lost-module data changes to its default or retains the last value.
Dense Protected Voltage Acquisition
- Multi-source monitoring: Fifteen compatible bipolar-voltage devices can occupy one VersaMax carrier position.
- Accidental overdrive: Enhanced fault withstand offers additional protection where wiring errors can expose an input to more than the normal measurement span.
- Remote collection: A VersaMax NIU can return the ordered channel data and module status from a distributed cabinet.
- Maintenance isolation: The conversion self-test helps separate an internal A/D problem from a field wiring issue.
