Y401-99-L 9DI + 9DO LoRa Wireless Digital I/O Module

Product Description

Y401-99-L is a 9DI + 9DO LoRa wireless digital I/O module for remote switching, pump interlock, industrial equipment control and alarm signal transfer. A typical application uses two matched bidirectional units: each input state is transmitted to the corresponding relay output on the other unit.

Best Fit

• Multi-channel remote switching between separated control panels.
• Pump interlock, industrial equipment control and alarm systems.
• Projects using dry contacts or NPN open-collector signals without a SIM card or Internet connection.

Operating Logic

• A dry-contact closure or active NPN signal on Device A DI activates the corresponding Device B relay output.
• When the input opens, the corresponding remote relay resets.
• The same input-to-output mapping works in reverse from Device B to Device A.

Key Specifications

• 9 NPN or dry-contact inputs and 9 relay outputs per unit.
• LoRa point-to-point communication with a matched bidirectional pair.
• Up to 5 km in standard open-area conditions.
• Fast communication range up to 1 km; this is separate from the standard transmission-distance specification.
• AC 100-240 V supply and maximum 3 W power consumption.
• Relay rating: AC 250 V 5 A or DC 28 V 5 A.
• Dimensions: 56 x 109 x 160 mm; weight: approximately 910 g.
• Operating temperature: -20 to +85 C.

Before Ordering

Confirm that the field signal is a passive dry contact or NPN open-collector output. DI is not a voltage input. Confirm the relay load, installation distance, antenna position and whether motors, pumps or other inductive loads require an external contactor.

This product is normally used as two matched units. Please confirm whether your quotation requires one module or a complete matched pair.
