Y301-220 and Y301-222 are compact Modbus RTU I/O modules with two digital inputs and two high-power relay outputs. Y301-222 adds two analog inputs for 0-10 V or 4-20 mA signals, so one module can collect status, switch loads, and read process values.
Best Fit
- Small pump, fan, lighting, and HVAC control panels.
- Equipment monitoring that needs both relay output and signal feedback.
- Projects that need two analog channels without adding a separate AI module.
Model Options
| Y301-220 | 2DI + 2DO, for equipment monitoring and relay control. |
| Y301-222 | 2DI + 2DO + 2AI, for control plus analog sensing. |
Key Specifications
- SPDT relay outputs rated 277 VAC / 10 A or 28 VDC / 10 A.
- Opto-isolated DI with pulse counting and configurable debounce.
- Y301-222 supports 0-10 V or 4-20 mA analog input, 16-bit resolution.
- Up to 4 local automation rules: follow, pulse, delay, schedule, cycle, threshold, and logic modes.
- 5 to 36 VDC input, hardware watchdog, Reload button, DIN-rail or screw mounting.
Before Ordering
Choose Y301-222 only when analog input is required. For digital-only control, Y301-220 keeps the wiring simpler.
