Features:
- Sixteen single-ended or eight differential voltage inputs
- Per-channel selection of 0–10 V or ±10 V ranges
- Channel alarms and separate module/user-supply status indicators
IC693ALG222 gives Series 90-30 projects a choice between maximum channel density and differential noise rejection.
The selected wiring mode changes both channel count and scan update performance.
Power planning includes the logic rail and the isolated 24 VDC field-side demand.
The General Electric IC693ALG222 Series 90-30 16-channel analog voltage input module may remain available for quotation and installed-system support from Apter Power.

Single-ended and differential use
- Single-ended density: Sixteen channels share the field reference for the highest point count.
- Differential option: Eight paired inputs measure the voltage between two signal conductors.
- Range choice: Every active channel can be configured for 0–10 V or ±10 V.
- Update behavior: Approximate refresh time is 6 ms single-ended or 3 ms differential.
Alarm and status information
- Channel alarms: Configured limits let the application flag out-of-range process values.
- Module indicator: A front LED reports the module electronics status.
- Supply indicator: A separate LED identifies the presence of user-side power.
- Fault separation: Status indications help distinguish backplane, user-supply, and signal-circuit problems.
Electrical integration
- Logic demand: The module draws 112 mA from the 5 VDC backplane rail.
- Isolated demand: The field section uses 41 mA from the isolated 24 VDC source.
- Isolation barrier: Field circuitry is separated from logic to 1,500 V.
- System limit: Maximum module quantity is governed by CPU support and baseplate power capacity.
Supported voltage measurements
- Multi-sensor acquisition: Sixteen common-reference sensors can be concentrated in one rack position.
- Differential transducers: Eight floating or noise-sensitive voltage sources can be wired as differential pairs.
- Bipolar signals: ±10 V operation supports bidirectional position, speed, and command signals.
- Process supervision: Channel alarms can identify measurements that cross configured operating limits.
