1. Overview
The Y331 fully isolated multi-range analog input modules belong to the YenGear Serial I/O Modules family. They provide 2, 4, 6, or 8 analog inputs for DC voltage and current acquisition.
Each input channel is isolated from the other input channels. Signal options cover millivolt, voltage, milliamp, and ampere ranges.
2. Ordering Information
2.1 Model Configuration
The four positions after Y331- follow DI / DO / AI / AO. Retain all four positions, including the final zero. Y331-0080 means 0 DI, 0 DO, 8 AI, and 0 AO.
| Model | DI | DO | AI | AO |
|---|---|---|---|---|
| Y331-0020 | 0 | 0 | 2 | 0 |
| Y331-0040 | 0 | 0 | 4 | 0 |
| Y331-0060 | 0 | 0 | 6 | 0 |
| Y331-0080 | 0 | 0 | 8 | 0 |
