Product Description

Y301-440 and Y301-444 provide four digital inputs and four relay outputs for Modbus RTU cabinet expansion. Y301-444 adds four analog inputs, making it a practical choice when a control panel needs switch status, relay control, and process signal acquisition in one module.

Best Fit

Multi-zone lighting, fan, valve, and pump control.
Cabinets that need balanced 4DI + 4DO remote I/O.
Process control panels that also need 0-10 V, 0-5 V, or 4-20 mA input.

Model Options

Y301-440	4DI + 4DO, compact digital I/O node.
Y301-444	4DI + 4DO + 4AI, for digital control with analog sensing.

Before Ordering

If your project only needs digital points, choose Y301-440. If analog sensors are part of the same cabinet, Y301-444 avoids an extra module.
