Analog Output Hardware
- The module delivers eight 0–20 mA outputs with 18 V compliance for precise current control.
- Each output uses a 16-bit digital-to-analog converter driving a transistor amplifier stage.
- Each channel includes a mechanical normally open relay for safe enable/disable control.
- LED indicators show relay and output status during operation and diagnostics.
- A built-in temperature sensor monitors internal heat to ensure reliable function.
Current Feedback Hardware
- Each output features current feedback using a 16-bit ADC and a 50-ohm sense resistor.
- The feedback loop maintains precise current accuracy and improves control stability.
- Ambient temperature limitations depend on installation density and airflow availability.
Compatibility & Control Modes
- Compatible with TBAOH1C and STAO boards, not with DIN-rail DTAO boards.
- Simplex Mode: Uses one I/O pack, basic fault detection, economical choice.
- Dual Mode: Uses two packs in parallel for redundancy and automatic failover.
- TMR Mode: Uses three packs with two-out-of-three voting for maximum reliability.
Installation Guide
- Mount the IS220PAOCH1B, REV B into a compatible Mark VIe chassis or terminal board.
- Connect the DC-37 output plug to the matching terminal board and tighten screws evenly.
- Ensure minimum loop impedance per GE manual to maintain stable output control.
