1. Overview
The Y331 analog input/output modules belong to the YenGear Serial I/O Modules family. Each module provides 1, 2, 4, 6, or 8 analog inputs and the same number of analog outputs for acquisition and control.
Input and output channels are separate. The RS485 and CAN options provide communication isolation; channel-to-channel isolation is not specified for these models.
2. Ordering Information
2.1 Model Configuration
The four positions after Y331- follow DI / DO / AI / AO. Retain all four positions. Combined models use Y331-00NN, where N is the count for each function, not the total I/O count.
| Model | DI | DO | AI | AO |
|---|---|---|---|---|
| Y331-0011 | 0 | 0 | 1 | 1 |
| Y331-0022 | 0 | 0 | 2 | 2 |
| Y331-0044 | 0 | 0 | 4 | 4 |
| Y331-0066 | 0 | 0 | 6 | 6 |
| Y331-0088 | 0 | 0 | 8 | 8 |
2.2 Interface Options
| Interface | Configuration |
|---|---|
| Isolated RS485 | Default; Modbus RTU |
| RS232 | Optional |
| Isolated CAN | Optional |
Specify the interface with the model when ordering.
2.3 Input and Output Range Options
| Function | Voltage ranges | Current ranges |
|---|---|---|
| Analog input | 0-5 V, 0-10 V | 0-20 mA, 4-20 mA |
| Analog output | 0-5 V, 0-10 V | 0-20 mA, 4-20 mA |
State the input and output ranges when ordering. Availability of different AI/AO ranges or mixed channel ranges is unverified for these models.
3. Key Features
- Differential analog inputs
- Read analog inputs and write output setpoints
- Power and communication indicators
- Parameter reset button and hardware/software watchdogs

5.2 Wiring Guidelines
- Identify channels using the labels on the selected module.
- Connect voltage inputs across the signal source and current inputs in series with the measured circuit.
- Wire AO to a receiver that accepts the ordered output range. Obtain the output load limits before selecting the receiver.
See the Technical Manual for input jumper selection, RS485 wiring, and commissioning.
