Y301-0004, Y301-0006, and Y301-0008 are Modbus analog output modules for generating 0-10 V or 4-20 mA control signals. They are used when PLCs, SCADA systems, or edge controllers need to drive valves, actuators, inverters, lab devices, or process setpoints through a serial link.
Best Fit
- Analog setpoint output for valves, dampers, actuators, and drives.
- HVAC and process skids that need Modbus-controlled AO channels.
- OEM systems that need voltage or current output without redesigning the controller board.
Model Options
| Y301-0004 | 4AO for small HVAC and OEM retrofits. |
| Y301-0006 | 6AO for mid-size process skids. |
| Y301-0008 | 8AO for higher-density analog output panels. |
Key Specifications
- 14-bit DAC with 0.001 V / 0.001 mA output steps.
- Configurable 0-10 V and/or 4-20 mA outputs, depending on SKU.
- Modbus RTU/ASCII, address range 1-255.
- 12 to 30 VDC supply, opto-isolated RS485 plus optional RS232.
- Power-loss memory can restore the last analog output after reboot.
Before Ordering
Confirm the output type for each channel. Combo versions use internal jumpers, so channel planning should be settled before installation.
