Analog Output IOP Comparison
| Function | IOP Models |
|---|
| AO (8 points) | MC-PAOX03 |
| AO (16 points) | MU-PAOY22 |
| Specification | AO (8 points) | AO (16 points) |
|---|
| Number of Channels | 8 | 16 |
| Smallest ORU | IOP | IOP |
| Redundancy | Yes | Yes |
| Redundancy Method | Outputs Electrically Isolated via Field Replaceable Relay Switch Module on FTA | Parallel Outputs — Solid-State Switch in IOPs |
| Redundancy Bias | Yes | No |
| Output Condition on IOP Failure | Configurable | Unpowered |
| Output Condition on PMM Failure | Configurable | Configurable |
| Single Channel Failure Robustness | High | Medium |
| External Connection Check | Yes | Yes |
| Standby Manual | Yes | Yes |
Notes:
- Optimal Replaceable Unit (ORU): The ORU is an item that can be replaced in the field with minimal impact on system operation. The IOP is an example of an ORU.
- Failure Detection Coverage: The redundancy failure detection is equivalent for both models.
- Channel Robustness: The AO8 provides individual power systems and DAC circuits for each output, while the AO16 uses shared power supply and DAC per IOP.
